Power planning 8 proposes 3 scenarios for power source development. The Institute of Energy (Ministry of Industry and Trade) has just released a report explaining the conclusions of Deputy Prime Minister Le Van Thanh on the national electricity development plan for the period 2021-2030 with a vision to 2045 (Planning for electricity development). electricity 8). In which, receiving opinions on reviewing the scale of power source development, reasonable power source structure compared to electricity demand in each period, especially in the period to 2030; In order to prevent unreasonable backup of power sources (such as the plan to develop the total installed capacity of 167GW of power sources by 2030, while the load demand is forecast at 86.3GW), the Consultant said Power planning. 8 proposed 3 scenarios for developing power sources to meet 3 scenarios of low load demand, base load and high load. The results of capacity balance of 3 selected scenarios show that renewable energy sources (wind and solar) have the proportion of 24% in 2020; 24-27% in 2030 and 38-42% in 2045 depending on the load scenario. The crude reserve ratio if including wind and solar is always high at 60-80%, but wind and solar power sources are variable renewable energy sources, contributing very little to power system redundancy, especially At the time of maximum load in the evening, there is no sun. Specifically, in the dry season, in the evening, when the national wind power occurs, it only reaches the guaranteed capacity (about 10% of the installed capacity for onshore wind and 20% of the installed capacity for offshore wind). ), at this time, the national crude reserve ratio of power supply will only reach 21% in 2020, 11%-14% in 2030 and 5%-8% in 2045 depending on the load scenario. The consultant said that in order to confirm the redundant or insufficient spare capacity, it is necessary to calculate the expected number of hours that do not meet the load demand. The calculation results show that the reserve scale as above ensures the reliability of the system’s power supply. The proportion of electricity from renewable energy sources (including hydroelectricity) in total electricity production of the selected scenarios all meet the objectives of renewable energy development in Vietnam’s Renewable Energy Development Strategy, reaching 32% in 2030 and 40.3% in 2045. According to the Institute of Energy, although the simulation of energy storage sources has been included, the minimum-cost planning model still chooses to cut a part of renewable energy to meet the flexible needs of the system instead. because investing in more storage resources, because investing in these resources will not be economically viable. The reduction rate calculated from the model is about 1.5% of renewable energy output/year (excluding cuts due to local transmission). The use of a partial reduction in renewable energy to meet flexible demand is used by countries around the world, and accepting a partial reduction in renewable energy is also one of the solutions. to develop renewable energy sources. At the request of ministries, agencies and appraisal councils, Power Master Plan 8 has included additional power source options that occur in addition to the above 3 scenarios to provide information for competent authorities to consider in determining the power supply. operating. In particular, the most difficult option to build power sources and grids is when there are risks of stacking, including high load growth and slow progress of thermal power sources (especially domestic gas exploitation sources). Accordingly, the proposal proposes to select the power source development scenario corresponding to the baseline load demand forecast, which is the selected scenario to calculate the design of the transmission grid, calculate economic and financial criteria. of Power Planning 8. At the same time, the project proposes a power source scenario corresponding to the forecast of high load demand to be considered for use in the management and development of power sources, ensuring to meet demand in the event that the national economy and electricity demand are met. load demand increased dramatically. In case of risk of stacking (high load, slow progress of coal-fired power sources, domestic gas-fired power sources), it will be necessary to add wind power, solar power, flexible power sources, etc. operate ICE to meet the demand for electricity and build more one-way lines from the South Central region to the North to transmit the capacity of power plants.

Bitcoin digital currency. (Photo: AFP/VNA) On May 28, British police said they had discovered a case stealing electricity large capacity to mine the digital currency bitcoin. Specifically, in a dismantling of a cannabis plant, the anti-narcotics police force in England suddenly discovered an organization Bitcoin “mining” using a large power source to steal from the national grid. The facility is located in an industrial area in Birmingham – the UK’s second largest city. Through inspection, the police discovered about 100 computers dedicated to “mining” bitcoin. At the time the police arrived, there was no one at the facility. The case is currently under investigation. The digital currency “mining” system consumes a large amount of electricity, so some lines specializing in “mining” cryptocurrency in the world often choose to steal electricity to reduce costs and increase profits. According to Deutsche Bank, “mining” bitcoin alone consumes the same amount of electricity as Switzerland consumes each year. On May 12, the world’s largest electric vehicle maker Tesla (USA) announced that it would stop using bitcoin in its car sales due to concerns about environmental issues. CEO (CEO) of Tesla, American billionaire Elon Musk states: “Tesla stopped using bitcoin car sales. We are concerned about the growing use of fossil fuels for bitcoin mining and trading, especially coal – the worst-emitting fuel.” Iranian President Hassan Rouhani has announced a four-month ban on all crypto-mining activities after many major cities suffered power cuts due to power shortages.

The study demonstrated a new approach to harnessing these frequencies, developing a new chip that can convert them into power for a small LED, possibly other small electronics and sensors. . Over the years, they’ve looked at a number of research projects aimed at capturing energy from radio waves, such as those generated by Wi-Fi, with some showing real potential. The idea is to turn the energy from these wireless networks so that it doesn’t go to waste and use it for power supply purposes. However, generating effective amounts of energy has so far been challenging. The researcher holding the chip has a series of small devices called torque oscillators that can power LEDs. The new technology, developed by scientists at the National University of Singapore (NUS) and Japan’s Tohoku University, uses a torque oscillator (STO). This is a relatively new class of micro-devices that are capable of generating microwaves, but have so far only resulted in low output power. Fusing multiple STOs together on a single chip is the way the scientists hope to increase this power output, but they have had difficulty determining the optimal configuration. Efforts are hampered by issues around distance and low frequency response. The authors of the new study designed and tested the new layout, where eight STOs are connected in a chain, which they say overcomes these problems. The new layout can take the 2.4 GHz radio waves generated by Wi-Fi signals and convert them into direct voltage signals. It will be fed into a capacitor and used to light up a 1.6 volt LED. Charging the capacitor for 5 seconds allows the LED to stay on for one minute, even after the power has been turned off. Study author Professor Yang Hyunsoo said: “We are surrounded by Wi-Fi signals, but when not in use to access the Internet, they will not work and this is a huge waste. The available 2.4 GHz radio waves become a source of green energy, thus reducing the need for batteries to power the electronic devices that we use frequently. In this way, small electrical devices and sensors can be powered wirelessly using radio frequency waves. With the advent of smart homes and cities, our work can create energy-efficient applications in communications, computers and neuromorphic systems.” The researchers will seek to enhance the energy harvesting capabilities of this technology by increasing the number of STOs in the chip. They will also explore how it is used to power other electronics and sensors. Huong Giang (via: New Atlas)

Term 2: Solve the quality management problem, electric vehicle regulations Electric vehicle charging station at AEON Ha Dong Shopping Center (Hanoi) – photo by Thanh Tung With more than 1 million electric scooters in circulation and thousands of electric cars handed over to customers by VinFast by the end of this year, the problem of quality management, registration, and charging station standards comes from The legal regulations in the circulation of vehicles for electric vehicles are in urgent need. Register like a traditional car At the end of March 2021, VinFast’s electric bus model was completed by the Vietnam Registry Department to verify design documents, vehicle safety testing and met the conditions of current automotive technical regulations. onions for mass production. Recently, VinFast has also announced to receive orders, produce an electric car model under 9 seats under the brand name VF e34, expected to hand over the car to customers in November 2021. In fact, electric cars have appeared in the country a few years ago and now there are 14 cars (all imported complete units, the Tesla brand). With the above trend, in the near future, the domestic market will have both imported CBU electric cars and domestically produced cars. Mr. Nguyen Van Phuong, Deputy Department of Motor Vehicle Quality – VAQ (Vietnam Registry Department), said that electric vehicles are quality controlled from the evaluation of vehicle design, safety testing to issue type certificates. and sample production. After the car is released, the circulation process, electric cars must be periodically registered as traditional cars. According to Mr. Dang Tran Khanh, Deputy Department of Motor Vehicle Inspection – VAR (Vietnam Registry Department), the biggest difference between electric cars and gasoline and oil cars is the energy source for the vehicle’s engine to operate. Therefore, the registry will apply the inspection of technical safety items according to the current national automotive technical regulations, except for the exhaust gas test, which will not be the same as gasoline or oil vehicles. “Currently, some countries like Singapore also test electric cars like conventional cars. However, the Vietnam Registry Department is consulting the experiences of countries and international automobile registration associations to take steps to research and prepare for the process of supplementing and completing the standards of cars, including cars. electricity ”, said Mr. Khanh. Which standard charging station? According to a recent study by the Research Group of the German International Cooperation Organization (GIZ), it is currently the beginning stage of the development of electric transportation in Vietnam. Imported electric vehicles including bicycles, electric scooters and four-wheeled passenger electric vehicles currently have more than 1 million vehicles. It is expected that by the end of 2021, there will be only electric cars produced domestically. About the current regulations applicable to electric cars, the representative of the Motor Vehicle Testing Center (Vietnam Registry Department) said that in-depth techniques for electric cars are electrical elements. There are a number of different research and development trends in the world. ” Electric car is still a manned car like a conventional internal combustion engine, so when the car is put into operation at present, there are no legal problems. Electric vehicle drivers, while participating in traffic in Vietnam, still comply with the current Decree 100 and the Law on Road Traffic
Decree 100 deals with the driver’s behavior more than the vehicle. And the current Law on Road Vehicle has regulations on vehicles, but in road motor vehicles, there is no regulation on engines. Therefore, the legal basis for electric vehicles is basically the same as conventional gasoline and oil vehicles, including procedures for vehicle registration and vehicle registration.
Mr. Khuat Viet Hung, Specialized Vice President of National Traffic Safety Committee ” Such as the standard of charging. Therefore, in this early stage, mainly based on the National Technical Regulation on technical safety quality and environmental protection for cars (QVN 09: 2015 / BGTVT) to test and evaluate. vehicle safety prices. At the same time, there is research to build appropriate standards for the development of electric cars in the country in the future. According to Mr. Nguyen Van Khoi, Director of the Department of Standards (General Department of Standards, Metrology and Quality), Vietnam currently has the standard TCVN 12241-3: 2018 on the secondary lithium-ion battery used for power transmission. for electric road vehicles. This International Standard specifies test procedures and acceptance criteria for the safety performance of batteries and masses of secondary lithium-ion batteries used to power road vehicles (EV). including battery electric vehicles (BEV) and hybrid electric vehicles (HEV). “However, we do not have a set of standards (required to apply) on charging stations and charging terminals. This is not even available in advanced countries. Just like the plug of household electrical appliances has not been agreed, where the power supply is 110V, where 220V, the device has a 3-pin or 2-pin plug, but the 2-pin plug is also each style. In addition, the structure of the electric vehicle charging station is also a technology secret issue, so no company wants to share it, so it has not been agreed to set which one is the standard. For example, the phone charger, until now it has been agreed, to buy any device, use the charger cord, the charger of that company, basically according to the original equipment manufacturer “, Mr. Khoi said. Just as a car powered by an internal combustion engine needs multiple gas stations, an electric vehicle (EV) also needs multiple public charging stations. The question is which technology standard charging station will Vietnam follow in order to be able to meet the maximum number of electric vehicles with different charging standards? According to Mr. Dao Cong Quyet, Head of the Public Relations Subcommittee of VAMA, there are currently 3 international charging standards for cars, including: Europe (CCS), Japan (CHAdeMO) and China (GB / T). ). If there are many electric car manufacturers, it is also necessary to have a common standard for the car manufacturers to plan to manufacture and import this type of vehicle for sale in Vietnam. Mr. Tran Quang Ha, Deputy Director of the Department of Science and Technology (Ministry of Transport), said that the charging standards of many basic companies according to Europe, but most of them do not have the uniformity of the common charging standard between the companies. Currently, road motor vehicles in Vietnam are basically all according to European standards. On the issue of waste disposal for electric vehicles, Mr. Ha informed that most countries have strict and strict regulations on waste product management. As for the discarded products containing harmful substances such as batteries and batteries, Vietnam has also had regulations but there are no sanctions. “When electric vehicles thrive, the problem of completing regulations on waste management and treatment such as batteries, batteries will be very hot. There should be clear sanctions “, Mr. Ha suggested.

Particularly Be Island – Bac An village. Binh (Ly Son) uses diesel power and solar battery system to supply electricity, the number of households with electricity reaches 99.68%. Commercial electricity output in 2020 will be 1,715 million kWh, up 10.6% compared to to 2019. In the first 2 months of 2021, reaching 324.5 million kWh, up 49% over the same period in 2020. The electricity industry always ensures safe, adequate and quality power supply for the above development needs. area “, Director of Quang Ngai Electricity Company Le Hoang Anh Dung said.

Before the impact of the early coming of the rainy season on the work of electricity safety, City Power Corporation. Ho Chi Minh City (EVNHCMC) has requested the affiliated power units to strictly respond 24/24 hours, at the same time, strengthen the inspection of preparedness and response when unexpected incidents occur. In particular, to ensure the safety of people and property, prevent and prevent electrical accidents that can occur when it rains, local flooding due to the influence of high tide or thunderstorms, high winds, trees. mortars fell … EVNHCMC gives warnings about electrical safety in the rainy season to the people of the city. Employees of EVNHCMC advise on safe and economical use of electricity in households Specifically, the city electricity industry. Ho Chi Minh City regularly and continuously propagates and propagates to customers who use electricity and people in the city understand and grasp the most basic contents of safe use of electricity in the rainy season. When detecting unusual phenomenon or loss of electrical safety, customers, people immediately call the hotline 1900 545454 (Customer care center of EVNHCMC) or phone number 114 – Fire department – Rescue, rescue city. Ho Chi Minh to be handled, prevented, and overcome in time. The electricity industry also recommends that, when it rains, people do not stay at the foot of the electric poles, under the eaves of the transformer station, do not directly touch the electric poles, ground wires, electric poles ligaments, electric meters, barrels. circuit breaker … In particular, do not go to the terrace, the roof where the power line crosses and do not manually repair the lines, outdoor electrical equipment. … Residents should disconnect the power supply (switch off the circuit breaker, CB) if the indoor area is flooded or the floor is wet by rain (splashing, leaking), wet from the electrical outlet, and wet with electrical equipment which can lead to the risk of local electric shock, likely to cause electric shock or fire, especially portable power tools such as hairdryers, vacuum cleaners … According to EVNHCMC, people should arrange places to install electric lines, power sockets, equipment using electricity in the house higher than the water level that is often flooded, wet; installing switchgear with appropriate anti-leakage (ELCB) function. In addition, people should cut off the power supply for electrical equipment installed outdoors (signs, billboards …) when it rains, strong winds. Especially, people need to stay away, warn everyone around them and set up barriers when it detects that electric poles have fallen (fallen), broken wires in roads, fields, lakes … Implement many measures to ensure electrical safety In order to ensure safety and prevent electrical accidents for people in the rainy season, EVNHCMC always gives top priority to grid safety. EVNHCMC has requested the heads of units to inspect and repair power grids in areas at risk of landslides, and even urgently move electrical works out of the landslide area to ensure safety. electrical works. In parallel, the city electricity industry. Ho Chi Minh City strengthened coordination with local authorities to carry out propaganda and warning among people not living, trading … near or below lines, power stations, electrical cabinets. At the same time, relieve cases of encroachment and encroachment on the safety corridor of high-voltage grid. In addition, EVNHCMC coordinates with the greenery management unit to promptly handle branches, branches, trees that can affect the safety corridor or may cause power grid problems when breaking or falling. , collision … At the same time, to strengthen the inspection of the power grid in order to promptly detect and resolutely not arise new points of violation of the high-voltage grid safety protection corridor that cannot be handled. The weather is becoming more and more complicated, besides the rain, there are often floods, so within the electricity industry, thoroughly grasp each officer, not letting subjective thoughts, neglect the object. with natural disaster prevention, fighting and response. EVNHCMC directs to bring into play the motto “4 on the spot” and the principle “3 ready” in preparing sufficient human resources, facilities, equipment and materials to be ready to respond when natural disasters occur unexpected incident. If there is any unexpected situation, it will ensure to re-establish electricity for production and daily life of customers in the shortest time.

Mr. Le Anh Duong – Deputy General Director of Hanoi Electricity Corporation (EVNHANOI) said that economical and efficient use of electricity is an important requirement in the context of a lack of power supply, especially at peak times. summer. Therefore, the propaganda on economical use of electricity has been deployed by the Capital’s electricity industry in many forms, such as through the online customer care system, organizing competitions, on the media … Meanwhile, the electricity industry implements technical plans, such as replacing all mechanical meters with electronic meters, combining daily metering database for each customer group …

Hanoi promotes efficient use of electricity

Specifically, in 2020, Vietnam Electricity (EVN) has built a website http://sudungdien.evn.com.vn, made a list of key energy users (customers with consumption rates). on average 3 million kWh / year or more) to monitor and recommend a reasonable and effective electricity use plan. As a result, in 2020, Hanoi has saved about 430.8 million kWh of electricity, equal to 2.15% of commercial electricity output, equivalent to about 870 billion VND.

In order to effectively implement the use of electricity economically, Ms. Nguyen Thi Thu Phuong – Head of Communication Department of EVNHANOI expressed, currently, the economical use of electricity still depends on consumers’ perception. One of the popular habits of people is not to turn off the lights when leaving the room or unplug the power plug when not in use. In fact, electronic devices, home appliances still consume energy when turned off but not unplugged. “The demand for air conditioning in urban areas is very high. Just each family can save about 10% of their electricity consumption by using equipment that applies new technology (such as inverter technology). the amount of electricity saved is not small, “said Nguyen Thi Thu Phuong.

Dr. Nguyen Quan, former Minister of Science and Technology, Chairman of Vietnam Automation Association, said that about 30% of electricity consumption is for lighting, including civil and public lighting. Saving half of the electricity used for this purpose is equivalent to not having to invest in building a power plant with a capacity of about 4,000 MW.

Focus on key solutions

Promoting electricity-saving solutions not only helps households, agencies and offices reduce costs, but also contributes significantly to ensuring electricity supply. Because now, Vietnam has to import coal for electricity generation and is expected to import liquefied gas by 2023. According to the report of the Ministry of Industry and Trade, with the scenario of an average growth of the gross domestic product of 7% / year, the energy demand by 2025 is 352 billion kWh and by 2035 is 506 billion kWh of electricity; which is equivalent to about 130,000MW of power capacity by 2030. This is a huge challenge facing the energy sector in Vietnam.

Information about the plan to implement the program of economical and efficient use of energy in 2021, Mr. Le Anh Duong said that EVN HANOI is continuing to synchronously implement propaganda measures to each household and operator. main career, production facilities … associated with technical solutions of operation, inspection and supervision. “For households, the electricity industry will coordinate with local authorities, launch the movement “Households save electricity, save energy”, striving for each district to have 500 households, each district has 300 households. typical household use of electricity. Currently, we are coordinating to organize Earth Hour campaign in 2021. This is an annual event that has the meaning of propagating extensively on energy saving.“, Mr. Le Anh Duong specifically stated.

In addition, the People’s Committee of Hanoi has issued the Plan No. 58 / KH-UBND on enhancing electricity saving in Hanoi city by 2021. Accordingly, the city sets a minimum saving target of 2, 2% of total power consumption. The City People’s Committee requires offices, offices, office buildings, schools, hospitals … to save at least 5% of the total power consumption annually. For restaurants, hotels, commercial service establishments, office complexes, apartment buildings, 50% of the capacity of advertising lighting, outdoor decoration must be reduced at night peaks as required by the establishment. local electricity authority …

The City People’s Committee also suggested that households use electricity in an economical and efficient manner, such as: Turn off electrical equipment when leaving the room, cut off the power if not using electrical equipment. The city encourages units and individuals to install rooftop solar power systems, hot water heating systems from solar energy to reduce electricity consumption …

For enterprises manufacturing, construction, the city proposed to give priority to the use of electrical equipment labeled with high efficiency energy; Use off-peak power reserve systems to use during peak hours. In addition, the installation of large-scale renewable energy systems is also a solution to reduce power consumption and even resell the power supply.

In addition, the City People’s Committee will provide technical assistance to the production, manufacturing, renovation and market conversion of vehicles, equipment, machines, production lines, construction works, and mats. public lighting, transportation, energy saving in households …; strengthening capacity for economical and efficient use of energy; Communication to raise public awareness about economical and efficient use of energy.
