Abstract:

Generating capacities of wind power and solar energy are affected by their conditions. Therefore, their outputs are highly unstable, intermittent and random. Largescaled gridconnecting of wind power and solar energy may cause considerable impact on the safety, stability and economic operation of the power grid. It is found out that hydropower, wind power and solar energy are complementary to each others by characteristic analysis. There is abundant hydropower ,wind power and solar energy of SichuanTibet section in the Jinsha River upper reaches, so it is possible to build a hydrowindsolar complementary renewable energy station since hydropower is of great regulating capacity. Utilization models of the renewable energy was explored based on cascade hydropower system of SichuanTibet section in the Jinsha River upper reaches. The coordinated development concept of the hydrowindsolar complementary system proposed can provide reference for the similar projects in other areas.
