摘要: 在中国风电发展十分迅速、弃风问题严重的情况下,近期需要进一步挖掘现有系统的调节能力。其中,促进水电与风电联合运行是有效措施之一。介绍了风电在日内和日间的有功出力变化特点,从电量分布特征、调节速度等方面分析了水电与风电联合运行的基础,进而研究了水电与风电在日内和日间联合运行的原理,及其对促进风电消纳、提高火电效率的作用。通过具体算例,分析了在是否考虑水电风电联合运行2种情况下,系统在风电消纳、火电煤耗、火电启停费用、系统燃料总消耗等方面的差异,验证了水电与风电联合运行的效益。

Abstract: Along with the rapid development of wind power in China in recent years, wind discarding problem is becoming increasingly serious. Further improving the regulating capacity of existing power systems is therefore needed. Combined operation of hydropower and wind power is one of the effective measures in the near future. In this paper, the intraday and inter-day output characteristics of wind power were introduced. On the basis of an analysis of the basis for combined operation of hydropower and wind power in terms of seasonal features and regulation speed, the combined operation principles of wind power and hydropower, and the benefits for promoting wind power accommodation and enhancing the efficiency of thermal power were studied. In order to compare the differences, two cases were designed. In one case the hydropower and wind power operated jointly, and in another case they operated separately. The differences of the two cases were analyzed in terms of wind power accommodation, coal consumption per kWh, thermal power start & stop cost, and the total fuel consumption. The results verified the benefits of the combined operation.

Key words: hydropower, wind power, combined operation
