The invention provides an integrated energy conversion and utilization system. A solar energy photovoltaic power generation system is directly connected with an electrical control system, a heat transfer medium of a solar thermal power generation system respectively enters into a high-temperature thermal storage system and an alkali metal thermoelectric direct converter integrated system after obtaining higher energy, then respectively enters into a condenser by a conductor temperature differential power generation system and returns to a solar thermoelectric system under the role of a pump, thereby forming a complete external circulation, wherein, the alkali metal thermoelectric direct converter integrated system and the semiconductor temperature differential power generation system are respectively connected with the electrical control system, and a valve is arranged on a pipeline which exits the solar thermal power generation system and enters the semiconductor temperature differential power generation system. The integrated energy conversion and utilization system carries out direct power generation by the solar energy photovoltaic power generation system and simultaneously utilizes the solar thermal power generation system for storing solar energy in the high-temperature thermal storage system by utilizing the heat transfer medium. The power generation is carried out through the energy cascade utilization way. The current direction of electrical energy is finally distributed by the electrical control system according to practical situations, thereby realizing the reasonable use of the electrical energy.
