Shangdu million-kilowatt wind power base project full-capacity grid-connected power generation
Since the beginning of summer, high temperature weather has continued in many parts of the country, driving a surge in electricity load. Relevant departments and related enterprises are going all out to ensure the supply of electricity and ensure the demand for electricity.
Among them, with the continuous expansion of the installed capacity of power generation, the role of new energy sources such as wind power and photovoltaics in ensuring energy supply is becoming more and more obvious. In view of the randomness, volatility, and intermittency of new energy, some new energy projects have realized the complementarity between different energy sources to ensure the safe and stable operation of the power grid.
On June 30, Huaneng Shangdu million-kilowatt wind power base project, the country's first "wind and fire bundled" new energy large base project, was connected to the grid for power generation at full capacity. The project will build 5 wind farms, 5 220 kV step-up stations and 1 500 kV central collection station, which can deliver 6.5 billion kWh of clean electricity to the Beijing-Tianjin-Tangzhou area every year, which is equivalent to reducing carbon dioxide emissions by about 540. tons. The project adopts the "wind and heat bundling" delivery mode, relying on the thermal power of 3.72 million kilowatts of Shangdu Power Plant, to play the role of thermal power peak regulation, to realize the coordinated optimization of thermal power and wind power, to ensure the safe and stable operation of the power grid, and to help meet the peak summer power supply.
On June 25, the first phase of hydro-photovoltaic hybrid power station project of State Investment Group Yalong River Lianghekou Hydropower Station - Kela Phase I photovoltaic power station was connected to the grid for power generation, marking the official commissioning of the world's first mega-kilowatt hydro-photovoltaic hybrid power station. The power station realizes the "bundling" of photovoltaic power generation and hydropower transmission. The hydropower station can adjust the photovoltaic power station within a day, promote the consumption of new energy, improve the utilization rate of the transmission line, and add another "new force" to the power supply guarantee in Sichuan and Chongqing.
SPIC launched a new model of energy supply guarantee, promoted the development and construction of "integrated smart zero-carbon power plants", and realized the integration and regulation of various distributed energy sources, energy storage and loads. Since the beginning of this year, 1.815 million kilowatts of new energy has been realized. Among them, 41 "zero-carbon power plants" were started, and 48 projects were completed and put into operation, with an installed capacity of 622,000 kilowatts, an aggregated adjustable load of 103,000 kilowatts, a peak capacity of 219,000 kilowatts, and a peak-shaving capacity of 301,000 kilowatts. In Zhejiang, the newly added peak capacity in the first half of this year exceeded one million kilowatts, and will achieve a peak capacity of 2 million kilowatts within this year.
Bozhong B2 offshore wind power project full-capacity grid-connected power generation
Recently, as the first affordable offshore wind power project of China Energy Group, the Bozhong B2 offshore wind power project was fully connected to the grid for power generation. The total installed capacity of the project is 501.5 MW, and 59 8.5 MW wind turbines are installed, which can generate about 1.589 billion kWh of electricity per year, which can meet the annual electricity consumption of 1.72 million households in Shandong Province. Since the first batch of wind turbines were connected to the grid for power generation, the project has generated approximately 157 million kWh of clean electricity.
In addition to new energy sources such as wind power and photovoltaics, as of the end of June, China National Nuclear Corporation's daily clean energy power generation exceeded 600 million kilowatt-hours, and 25 nuclear power units in operation have achieved all peak output, ensuring power production and supply during the peak summer and meeting the needs of the people. Mass production and living energy demand. From June 20th to 30th, the two million-kilowatt-class nuclear power units of SPIC’s Shandong Haiyang Nuclear Power Plant continued to operate at full power. They have generated a total of 650 million kWh, which can meet the electricity consumption of about 270,000 households for a year.
In terms of hydropower, China Huadian Qianyuan Electric Power takes full advantage of the complementary advantages of water and light in the river basin, and uses the sending channel of the Beipan River Basin to make good use of every drop of water and every inch of light. State Power Investment Jiangxi Company has carried out work such as vacating storage in advance, storing flood tails, and cascade dispatching. This year, it has increased power generation by 43.15 million kwh. Wuling Power has cooperated with professional departments to artificially increase rainfall.
According to a report released by the China Electricity Council a few days ago, the country's highest power consumption load will be about 1.37 billion kilowatts in 2023, an increase of 80 million kilowatts compared to 2022. If there is a long-term and large-scale extreme climate, the national maximum power load may increase by 100 million kilowatts compared with 2022.
On June 30, the State-owned Assets Supervision and Administration Commission held a meeting to promote the energy and power supply of central enterprises. It was required to take the initiative to act based on the present, and do everything possible to ensure the safety and supply of the summer peak. Power generation companies should make full use of power, coal companies should make every effort to ensure the supply of coal, and power grid companies must resolutely guard the bottom line of electricity consumption for people's livelihood and safe production.
Li Chuangjun, director of the New Energy and Renewable Energy Department of the National Energy Administration, said at a press conference held by the National Energy Administration that he will coordinate the safe and stable operation of the power system, reliable power supply and new energy consumption and utilization, and comprehensively improve the regulation of the power system. Capacity and flexibility, to ensure that new energy can be "developed, supplied, and used well".
