光伏-光热联合基地最优储热容量规划与经济性研究OA

To promote the complementary and collaborative development of photovoltaic and solar thermal power generation and enhance the economic efficiency of the combined system,an optimization study on the storage capacity is carried out.A mathematical model of the combined system is constructed,and an operation strategy of'photovoltaic priority,solar thermal peak shaving,and storage shift'is established.An optimization model for storage capacity based on minimizing the levelized cost of electricity(LCOE)is established,and a simulation is conducted using a certain base station in Northwest China as the research object.The results show that there is an optimal storage duration(8 h)in the system,which results in the lowest LCOE.Sensitivity analysis indicates that the investment cost of solar thermal power and the discount rate are the most sensitive factors affecting the optimal configuration.
