Abstract

Taking the integrated project composed of photovoltaic power generation and tower solar thermal power generation （hereinafter referred to as photovoltaic thermal integration project） as the research object, taking advantage of the low cost of photovoltaic power generation and the low cost of solar thermal energy storage, solar thermal power station is equipped with electric heating equipment, photovoltaic power generation priority to meet the demand for heat storage capacity, and stored electricity is issued in the evening peak hours. Ensure the power supply, through the calculation and analysis of the peak capacity and heat storage capacity utilization of photovoltaic thermal integration project in the evening peak hours, and determine the optimal configuration scheme of electric heating device with the minimum demand for on-grid electricity price of solar thermal power station in peak hours as the goal. The results show that the photovoltaic solar-thermal integration project is eqvipped with a reasonable scale of electric heating device, which can improve the peak capacity of the integration project after complementary operation, get the biggest profits in the future power market.
