风光水火储多能互补能源基地电源容量规划研究OA

As the power supply structure gradually shifts toward a diversified pattern,the risk of regional renewable energy consumption increases.In order to maximize the utilization of the existing adjustment capacity of hydropower and thermal power and improve the consumption level of wind power and photovoltaic power,a multi-energy complementary energy base including wind power,photovoltaic power,hydropower,thermal power and energy storage is constructed,and the advantages of complementary power generation among wind power,photovoltaic power,hydropower,thermal power and energy storage compared to other power generation modes are analyzed.Based on 8 760 time series points throughout the year,a multi-objective power generation capacity planning model that takes into account system reliability,economic benefits,environmental benefits,and the consumption level of renewable energy is constructed,and multi-objective optimization is achieved through the linear weighting method of unit standardization of the objective function.Finally,the annual historical wind and solar data of a certain place are selected for simulation experiments.The results show that,compared with single-objective optimization,multi-objective optimization can effectively balance the equilibrium points among different optimization objectives,avoid the limitations of single-objective optimization,and by rationally adjusting the output of hydropower,thermal power and energy storage,the complementary coordination of wind power,photovoltaic power,hydropower,thermal power and energy storage on multi-time scales can be achieved.
