Control room of Ham Thuan factory with IP-based surveillance camera system Start digital transformation from equipment upgrade projects Concept “ Digital conversion ” has been widely used in the media in recent times. Since it is a new concept, each person can understand digital transformation in his or her own way. However, the basic thing of digital transformation is that the process of digitalization combined with the application of achievements of the Industrial Revolution 4.0 into practice has created many transformations. powerful changes in life. The application of digital technology (Digital technology) has been approved by the Company UD implemented since 2004 when implementing the Da Nhim Power System Restoration Project. Da Nhim hydropower plant was put into operation in 1964 with a control system based on analog signals with countless knobs, knobs, switches, switches… The system of bulky, power-consuming equipment is prone to breakdowns due to its long-term use, reducing reliability. After 40 years of operation, the equipment system needs to be replaced to meet the reliability and efficiency in power production. Operation room of Da Nhim hydropower plant before digitalization Da Nhim power system restoration project (2004 – 2006) was invested by Vietnam Electricity Corporation (now Vietnam Electricity – EVN) and assigned Da Nhim – Ham Thuan Hydropower Company – Da Mi (now Da Nhim – Ham Thuan – Da Mi Hydropower Joint Stock Company: DDD) is the Project Management Board. The project includes 3 main packages to renovate and replace Da Nhim’s equipment system, including: Package No. 1- Generator and electrical equipment; Package No. 2 – Water turbine and water pipeline equipment; Package 3 – Hydrological data collection system. In particular, Package 1 with the application of digital technology to electrical equipment and control systems has created a new and modern appearance for Da Nhim hydropower plant with a stable operating equipment system. , computer controlled high availability, replacing obsolete analog equipment system. The control system with Alstom’s ALSPA P.320 HMI interface combined with GE Fanus’ PLC has created a turning point in operation control. All operation of the device is done by clicking on the computer screen instead of turning the knob or pressing the mechanical button as before. OCC operation room of DHD Company – The first remote control model of power plants in the power industry Da Nhim Hydropower Plant Expansion Project (Operating Phase 1 with a capacity of 80MW in 2018) continues to apply the latest digital technologies to the control equipment system, creating a Da Nhim hydropower plant. more modern. Inheriting their knowledge and experience through the Da Nhim Restoration Project, the Ham Thuan – Da Mi Hydropower Project, from 2008 to 2010, the Company’s engineers UD has successfully researched, programmed and put into operation the DCS system of Song Pha hydropower plant with a combination of WinCC control interface and Siemens S7-300 PLC. With the new control system, Song Pha hydropower plant seems to be wearing a new shirt, the outdated analog control system has been completely replaced by digital equipment. Operation room of Song Pha hydropower plant in 2006 The memorable milestone of the application of Science and Technology 4.0 in power production operation was in 2013 when the General Assembly Company and the domestic contractors successfully installed and put into operation the Operation Control Center (OCC – Operation Control Center). Center). This is considered the first OCC center at power plants in Vietnam to remotely control power plants. Since the OCC Center came into operation, combined with the IP-based CCTV system, DHD Company has optimized its operation and improved labor productivity. With OCC’s remote control and monitoring capabilities, the number of operators at hydroelectric power plants is reduced from 5 to 2 to 3. The OCC model of AGM Company was then replicated to other units in the industry and brought many practical benefits. The operation room of Song Pha hydroelectric power plant is now with the control system designed and installed by DDH Company Combining digitization and industrial science 4.0 Responding to the digital transformation of Electricity of Vietnam (EVN) and Power Generation Corporation 1 (EVNGENCO1), the General Assembly Company applied the results of the Industrial Revolution 4.0 on the digital platform to create a remarkable transformation in production management and administration. On the digital platform that has been deployed at power plants, DDT Company has gradually upgraded telecommunications infrastructure to create a smooth connection between the OCC Center, power plants and dispatching centers for business purposes. operate production and offer electricity prices in the market with high efficiency. The application of IP-based surveillance camera system helps the operator to monitor lake water level, discharge status of water supply to downstream… creating many advantages in coordination between the Company and local authorities in the company. disaster prevention and search and rescue.

CleanMax will own and operate the above projects, while Facebook will buy electricity from the Indian grid. Facebook’s head of renewable energy, Urvi Parekh, said the tech company usually does not own the power plants, instead signing a “long term” power purchase agreement with the renewable energy company. According to her, this will help projects find the necessary capital. India is currently Facebook’s largest market in terms of users. Meanwhile, in Singapore, Facebook has also announced similar partnership arrangements with energy suppliers such as Sunseap Group, Terrenus Energy and Sembcorp Industries, which can generate 160 MW of solar power. Power from these plants will be supplied to Facebook’s first data center in Asia and located in Singapore, the facility expected to come online next year. Last year, the International Energy Agency (IEA) said data centers were causing technology companies like Facebook to consume about 1% of all global electricity. Tech companies like Amazon, Alphabet Inc and Microsoft have pledged to move towards zero carbon emissions and achieve zero net emissions, amid demand for digital data and services. ants will increase steadily. Facebook CEO Mark Zuckerberg on April 15 announced that the company’s global operations are now run entirely on renewable energy and have reached zero net emissions.

Solar power is Qatar’s strength

Huge solar power potential

Qatar and the GCC countries have the highest potential for harnessing solar energy, based on the annual amount of sunshine (including hours of sunshine and solar intensity). Not to mention, July, August and September every year is the time when the whole region has the highest amount of electricity consumption, due to the very high demand for air conditioning and also a strong solar irradiation time most of the year.

Therefore, the development of solar power technology is the most promising energy sector for Qatar. In early 2020, Qatar announced it would build a solar power plant with a peak capacity of 800 MW at Al Kharsaah, comprising 2 million two-sided photovoltaic modules (Bifacial technology) combined with tracking equipment. width over 1,000 hectares. Al-Kharsaah solar power plant will be built on 10km2 near the capital Doha, expected to be completed in 2022.

The Al-Kharsaah Solar Power Plant will reach maximum capacity when solar radiation peaks at noon – the time when the demand for electricity is highest during the day. With a two-sided photovoltaic module system incorporating a monitoring device to align the angle of sunlight absorption, the correlation between solar power production and electricity demand will be strengthened.

Total Energy (France) and Marubeni Trade and Investment (Japan) will sponsor the Al-Kharsaah Solar Power Plant Project, with a total investment of about 500 million USD (ie 0, USD 6 / Wp for Bifacial technology with tracker). This figure shows that the solar energy sector is on a constant and relentless trend of cost reduction. With the use of monitoring devices with a two-sided module, the load factor of a solar power plant can exceed 30% – an exceptionally high level in the solar sector, due to the home load factor. Average solar power in the world is only about 20%.

Fresh water is Qatar’s big problem in climate change

Electricity and water – Two main concerns

Solar PV can play a central role in meeting the growing demand for electricity and water in Qatar, as the two sectors are interrelated (large gas thermal power plants can produce water from desalination). However, the demand for water and electricity in summer is very high: Electricity peaks reach about 8 GW, double the capacity in winter; while the water demand is about 20% higher.

It should be noted, in recent years, electricity demand in Qatar has grown three times faster than the world average due to the country’s strong economic growth and infrastructure projects. giant. The high level of electricity consumption is also due to the government price subsidy that makes electricity prices almost “free” in Qatar, suitable for all purposes.

The demand for fresh water in Qatar is growing at a rate of 12% per year, mainly due to industrial development, population growth as well as increased irrigation in the agricultural sector and anti-desertification. Since then, the desalination process has been significantly accelerated, contributing to increased power consumption.

Qatar in the Global Energy Transition Race (Next and Out)

Increase the share of renewable energy

Qatar is implementing a series of measures to reduce greenhouse gas emissions and assert its position as a leader in the development of new technologies.

Domestically, Qatar aims to increase the share of renewable energy in electricity consumption to 20% from 2024. At the same time, the transformation of energy in Qatar is also the realization of the development of public transport systems. new projects, including electric taxis and compressed natural gas (CNG) buses.

Qatar has established official bodies to deal with climate change (for example the National Committee on Climate Change – the national body responsible for climate policy formulation). Moreover, Qatar has participated in the GHG reduction program of the World Bank (WB) and the Global Association for Reducing Gas Emissions (GGFR). More specifically, Qatar Petroleum National Petroleum Company sets a “zero gas emission” goal by 2030. This goal will help develop new insights for other gas producing regions. Qatar Petroleum is promoting carbon capture and storage projects as it sees customers increasingly opting for low-carbon resources.

Qatar will need to make efforts to invest in low-carbon energy technology, by developing goals for energy efficiency and carbon concentration. Thereby, the challenge of Qatar is the reconciliation of new goals in the fight against climate change with the development of the domestic energy sector, along with new and “cleaner” sectors.

In recent years, electricity demand in Qatar has grown three times faster than the world average due to the country’s strong economic growth and huge infrastructure projects. The high electricity consumption is also due to the government price subsidy that makes electricity prices almost “free” in Qatar.
