| Popis: | With the large-scale development of wind resources, the problem of abandoning wind power is becoming increasingly serious. In order to improve the power supply structure and reduce wind abandonment, this paper configures thermoelectric power for long-distance high-voltage power transmission for wind farms. Based on historical data, it analyzes the output characteristics of wind-heat hybrid energy, proposes a method for determining the transmission capacity of wind-heat hybrid power generation based on confidence conception. The long-distance DC transmission evaluation index system of wind-heat hybrid energy and different transmission schemes are established. Finally, the schemes are comprehensively optimized based on the regret theory method. The example shows that the selection method proposed can effectively combine the source characteristics, economic and technical factors of the transmission grid to give the applicable scope of different transmission schemes. It provides a reference for the long-distance transmission planning of wind energy. |
