China's wind power industry has developed rapidly in recent years. On the one hand, wind farms are staking the “wind†and blindly building. On the Other hand, because of the poor access to the grid, it is like the narrowness of vehicles and the phenomenon of abandoned winds and litters. This phenomenon is particularly prominent in the northeast, northwest, and north China where wind resources are abundant. How should the emerging energy industry emerge from the dead end?
"The relationship between the power supply and the power grid is like the relationship between the car and the road. If the road is not repaired well, it will cause 'congestion'." Zheng Taiyi, head of the dispatching communications center of Jilin Electric Power Co., Ltd., said that the wind power station in Jilin Province is located in a wide area. Lean, weak power grid, the maximum load is only about 900,000 kilowatts, and the current installed capacity of wind power is close to 2 million kilowatts, when the wind power is large, transmission lines often close to full load, had to take measures to abandon wind.
Disadvantages are unfortunate, but the main reason behind this is blind construction. Zhang Zhengling, spokesperson of the State Grid, said that the seriousness of the northeastern abandonment of wind is caused by the large-scale development of wind power to cause overcapacity. For example, the volume of Jilin wind power development does not match its own economic volume. Because the local thermal power units are mostly combined heat and power, When the winter heating, the minimum load of the thermal power unit can only be reduced to 90%, and wind power can only make concessions.
As China's wind power-rich region is far from the power load center, and the rate of increase in power generated by economic development speed is difficult to quickly increase in a short period of time, some people in the industry have proposed that we should speed up the use of ventilation and export channels to increase smart grid construction. Solve problems such as wind blowing. In addition, wind power planning should avoid blind expansion and fully consider the patency of power transmission channels.
Experts pointed out that the development of wind power can not only look at wind resources, must take into account the consumption and transmission costs of the power grid. China's wind power development plan focuses on resource planning and lacks specific plans for wind power transmission and wind power consumption. Relevant state departments should study the subsidy policy, direct more wind power investment to the correct and efficient places, and guide areas that can be connected to the network and can be eliminated, and solve grid connection problems at the source.
