摘　　要：针对风电、光伏发电出力不稳定问题,提出水光风互补运行方式。选取金沙江上游典型水光风电站(岗托水电站、盐边万家山光伏电站、德昌风电场)进行出力特性及其互补性分析。在此基础上,采用Visual Basic 6.0编程,建立日内实时互补模型,进行金沙江上游典型电站水光风互补运行研究,即在电网总负荷、风电和光伏出力已知的情况下反推水库运用过程。研究表明:水电、光伏和风电出力在年内和日内具有一定的互补性,三者联合运行,能在一定程度上降低风电和光伏发电并网给电力系统带来的负面影响,这对改善环境条件,优化能源结构具有重要意义。To reduce the effect of instability in outputs of wind farm and solar power, complementary operation modes of them together with hydropower are presented in this paper. We chose three typical power stations on the upper Jinsha, namely the Dechang wind farm, Wanjiashan solar power station, and Gangtuo hydropower station, and analyzed their power output features and complementarity at time scales of a day, a month and a year. A real time model of complementary operation was developed and coded in visual basic and then applied to calculation of reservoir operation modes under the condition that the total power grid load, wind power output and photovoltaic output were all known. The results show that a complementary operation mode of merging three types of outputs before connected to the power grid can lower the negative impact of instable wind and solar power and improve power transmission efficiency, thus showing a great significance in improving the environments and energy structure.
