Abstract

The invention discloses a photothermal photovoltaic combined power generation system and method, the system comprising: an endothermic working medium storage unit, comprising a first storage element (11), a second storage element (12) and a third storage element (13); the first storage element, the second storage element and the third storage element are configured to store the endothermic working mediums at different temperature stages; a concentrating heating unit (2) for transporting the endothermic working medium in the first storage element to the second storage element after concentrating and heating; an auxiliary electric heating unit (3) for electrically transporting the heat absorbing medium in the second storage element to the third storage element after being electrically heating; a photovoltaic power generation unit (4) for performing photovoltaic power generation and providing power to the auxiliary electric heating unit; a heat exchange unit (5) for heat exchange processing of the endothermic working medium and the power generation working medium, and transporting the endothermic working medium to the first storage element, and transporting the power generation working medium to the power generating unit; a power generating unit (6) configured to generate electricity by the power generation working medium output by the heat exchange unit. The present invention can avoid the problem of high heat loss of the photothermal collector under high temperature conditions, and simultaneously improve the operating temperature of the subsequent power generation cycle process, thereby improving the overall power generation efficiency of the power generation system.
