For the wind-solar-thermal-storage complementary power generation system without conventional power supply support, coordinated planning of installed capacity is of great significance to improve the operation economy and utilization rate of the power generation system. A two-layer optimal configuration method is proposed. The upper layer determines the installed capacity of the system with the minimum levelized cost of energy and the abandonment rate as the goal. The lower layer aims to maximize the consumption of new energy power generation and solve the problem of power distribution. The system capacity configuration is obtained by iterative optimization. Then, the optimization results are selected through Nash negotiation. Finally, the simulation analysis is carried out with the data of Hexi area in Gansu Province. The results show that, the levelized cost of energy is 0.306 4 yuan under the optimal capacity configuration of the wind-solar-thermal-storage complementary power generation system. The optimal ratio of the installed capacity of the wind farm plus photovoltaic power station to the installed capacity of the photothermal power station is 6:1. Compared with the wind-solar hybrid power generation system with the same installed capacity, the wind-solar-thermal-storage complementary power generation system has higher stability.
