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.

EVNCPC strengthens the inspection and repair of the power grid to ensure that customers do not cut off electricity during the holidays of April 30 and May 1 this year. (Photo: Tel). Mr. Nguyen Thanh – Deputy General Director of EVNCPC said that on the occasion of April 30 and May 1 this year, employees are entitled to 4 days off, so EVNCPC forecasts the demand for electricity for domestic activities and public holidays. This will also increase. In order to ensure safe and continuous electricity supply to over 4.3 million customers in the Central region – Central Highlands, in addition to focusing on power sources for political events in 13 provinces and cities in the region, EVNCPC has a specific plan to not cut the power from 0:00 to 24h00 on April 30 and May 1, 2021. At the same time, from the time before the holiday, 13 Electricity Companies under EVNCPC have also actively worked with the local authorities to grasp the time and venue of festivals, festivals, and arrange the mode of power supply. reasonable for safe operation, reliable power, grid under normal conditions and flexible switching in fault situations. In particular, the units give priority to electricity assurance at the locations where the local political and cultural activities take place. With venues where major and important political and cultural events take place, in addition to the national grid, EVNCPC also directs its affiliated Power Companies to consider and arrange backup diesel generators; re-established the duty shift at 110kV substations without personnel on duty. The units strengthen inspection, detect and promptly handle defects of source equipment, power grids, unmanned 110kV substations, SCADA systems, luminescence to ensure safety of the corridor to prevent incidents. in electrical system operation. During this time, the units throughout EVNCPC arranged to strengthen the organization of leaders, mobile operators, operation, power repair, troubleshooting of private telecommunications network system. ; At the same time, fully preparing supplies, backup equipment, fuel, communication systems and vehicles, ready to quickly handle damage and incidents. EVNCPC requires its affiliated Power Companies to promote propaganda among the people to prevent kites flying near electric lines, metal-coated paper fireworks and throwing objects on the line causing violations. grid safety corridor; coordinate with localities and information agencies in organizing propaganda and widely dissemination of measures to use electricity safely, economically and effectively to customers using electricity. Especially on this occasion, the Center for Customer Care in Central Vietnam strengthened the call center force 19001909 to receive and well handle information related to the power supply in the area, promptly responding to requirements and problems of customers./.

Illustration. TASS. Igor Pshenichnikov, responsible for the Amur-LNG project, said Russian experts are developing a reusable methane rocket engine for the Amur boosters that can redirect carriers. off the launch pad in the event of take-off malfunction. “We are planning to deploy a hot backup and guidance system in the Amur boosters,” he said. If one of the motors fails, it will be turned off while the operation of the other thrusters will be accelerated. The lead expert explained: “In this situation, the quest continuation option would be considered.” If damage occurs during takeoff or near the ground, the missile will not be able to launch due to its large mass. That is why the missile is diverted to a safe distance so as not to damage the launcher. Russian State Space Corporation Roscosmos and Progressive Space Missile Center signed a contract in October 2020 for the design of a space missile system concept with reusable methane-fueled rockets. The first Russian Amur application. The missile will be launched from Vostochny aerospace in the Russian Far East at a stage of reuse. In February, Dmitry Baranov – Director of the Advanced Space Rocket Center (a division of Roscosmos) said work on the conceptual design of the methane Amur fuel missile will be completed by the third quarter of 2021. . Amur is a commercial missile carrier. With the reuse phase, it will be able to put the payload of up to 10.5 tons into orbit as low as Earth, compared with the 8.5 tons carried by the Soyuz-2 rocket.
