State Grid: Consumption of 90 million kilowatts of wind power in 2015

State Grid Corporation of China announced on April 15 that “The State Grid Corporation of China promotes the development of wind power”, and relevant persons of the State Grid stated that by strengthening the construction of cross-regional power grids and constructing the “Three Chinas” power grid, the nation’s capacity for absorbing wind power can be significantly increased. It is estimated that by 2015, the scale of wind power consumption in China will exceed 90 million kilowatts, and by 2020 it will reach 150 million kilowatts or more.

In spite of this, China's wind power development is also facing challenges from both the grid connection and consumption. Shi Lishan, deputy director of the New Energy and Renewable Energy Division of the National Energy Administration, said that the Energy Administration is stepping up efforts to formulate operational requirements for wind power companies and establish a strict and effective wind power operation system to promote sound development of the wind power industry.

The data on the improvement of wind power grid connection capacity shows that by the end of 2010, the nationwide wind power grid connection capacity was 29.56 million kilowatts, and the average annual growth rate of wind power grid connection capacity during the “Eleventh Five-Year Plan” period was close to 100%. In 2010, the average utilization hours of wind turbines nationwide was 2,097 hours, and the proportion of wind power generation in Mengdong, Mengxi, Jilin and Heilongjiang to local social power consumption reached 21.1%, 8.7%, 5.6%, and 4.6% respectively. Wind power utilization Has reached a higher level.

The relevant personage of Jilin Provincial Energy Bureau stated that Jilin Province is one of the eight wind power bases in the country and the wind power industry has shown rapid development. However, with the continuous increase in the proportion of wind power connected to the grid, the peak power of the local power grid is very low, which will affect the normal operation of the power grid. Therefore, it is imperative for the local government to speed up the construction of peaking power, such as pumped storage, and accelerate the development of UHV lines. Construction speed.

According to relevant sources from the State Grid, in terms of grid-connected technology standards, the State Grid has promoted the construction of a wind power grid-connected enterprise standard system and participated in the compilation of wind power national standards and industry standards. At the same time, in order to meet the demand for large-scale wind power grid connection to the system's peak shaving capacity, the company actively develops plans and constructions for pumped-storage power development.

For the future development plan of the wind power industry, authorities of the State Grid stated that the company will continue to accelerate the construction of UHV and cross-regional power grids, smart grids and pumped-storage power stations, and strengthen the early phase of wind power transmission projects, wind power grid-connected detection and priority dispatching of wind power, We will deepen the research on major issues and key technologies for wind power development, establish statistical information analysis platforms for wind power information and international cooperation and exchange platforms, and further promote the scientific development of the wind power industry.

Wind power operation will be institutionalized. Shi Lishan introduced that at present, China's wind power industry is experiencing rapid development, but it also faces many problems including grid connection, dispatching, and consumption. It requires governments, power grids, and wind power companies to cooperate and coordinate with each other to jointly solve problems. . The National Energy Administration will regulate all parties by formulating a set of strict and effective wind power operation systems.

He believes that when formulating wind power development plans, the government should pay more attention to the relationship between national wind power planning goals and local wind power planning goals, and handle the relationship between power grid construction and wind power project construction and operation. For grid companies, the grid needs to accelerate the construction of high-capacity grid lines across provinces and regions, and at the same time improve the level of intelligence in the grid to ensure that more wind power can achieve friendly access to the grid and optimize dispatch. In addition, power grid companies should also increase the efforts to build peak power supplies such as pumped storage.

For wind power enterprises, it is necessary to focus on improving the operation and management capabilities of enterprises and the forecasting and forecasting capabilities of wind power resources. At the same time, wind power equipment manufacturers must improve the reactive power compensation capabilities of wind power equipment.
