Evaluation Method for Regulation Performance of Hydropower Unit Integrated with Wind and Photovoltaic Power
In response to carbon peaking and carbon neutrality policy,the proportion of wind and photovoltaic power in the grid will increase.By 2050,the total installed capacity of wind and photovoltaic power is estimated to account for 70％of China's power supply.To ensure the stable operation of the grid after wind power integration,it is necessary to utilize hydropower resources for balancing.The volatility of wind and solar power requires frequent involvement of hydroelectric units for regulation,which changes the dynamic characteristics of hydroelectric unit regulation.To quantitatively evaluate the regulation performance of hydropower units integrated with wind and photovoltaic power,we established an evaluation system for the regulation performance of hydropower units.First,we constructed an index system that reflects the regulation performance of hydropower units.Subsequently,by using the fuzzy comprehensive evaluation method,we comprehensively evaluated the regulation performance of hydropower units integrated with wind and photovoltaic power.The proposed method in this paper provides theoretical support for the grid connection of wind and photovoltaic energy,and contributes to the development of hydro-wind-solar energy complementary integration.
