Methods on scheduling of hydro-photovoltaic complementary system

The hydro-photovoltaic complementarity is an important operation mode to promote the grid-connected absorption, and one of the main directions of solar energy development and utilization in the future. The paper expounds the principle of hydro-photovoltaic complementarity and the influence of the installed ratio on economy, also summarizes and analyzes the research results of hydro-photovoltaic complementary system operation scheduling methods. In view of the uncertainty of hydro-photovoltaic complementary generation, the paper proposes several suggestions and expectations for the study of hydro-photovoltaic complementarity, to provide ideas for improve the economy and reliability of short-term and large-scale hydro-photovoltaic complementary operation.
