Research on optimal operation for long-term complementary power generation of wind-photovoltaic-hybrid storage system
摘要
Abstract
To investigate the long-term complementary regulation capability of hybrid pumped-storage power stations under the background of grid integration of large-scale wind and photovoltaic power,an optimal operation model for long-term complementary power generation of wind-photovoltaic-hybrid storage systems was developed.This model aims to maximize the utilization of wind and photovoltaic power generation in the joint operation of wind-photovoltaic-hybrid storage systems by minimizing the variance of residual load,and it was solved using a progressive optimization algorithm.The results of a case study show that compared with the wind-photovoltaic-hydro system without reversible pump-turbine units,the expected value of the utilization rate of wind and photovoltaic power in the wind-photovoltaic-hybrid storage system increases by 8.56%,and the expected value of the variance of residual load decreases by 99.38%.These results indicate that the hybrid pumped-storage power station can better play its role in regulating wind and photovoltaic power,and can improve the utilization rate of wind and photovoltaic power generation and the power generation capacity of the wind-photovoltaic-hybrid storage system while meeting the demand for tracking grid load.关键词
