Abstract

The invention provides a photovoltaic-thermoelectric electricity generation power synthesis system, which comprises a collecting lens array, a photovoltaic cell, a thermoelectric engine, a direct-current motor and an alternating-current generator, wherein rotating shafts of the thermoelectric engine, the direct-current motor and the alternating-current generator are connected together; an output of the photovoltaic cell is connected with an input end of the direct-current motor; the direct-current motor is driven by power generated by the photovoltaic cell; and the power generated by the direct-current motor and the power generated by the thermoelectric engine are used for driving the alternating-current generator to generate electricity in common, and are conveyed into a power grid through a power distribution system. The invention provides a method for integrating photovoltaic output and power output of the thermoelectric engine. Therefore, high-quality power supply can be provided; the stability of solar electricity generation power is increased; the pressure to the power grid due to the instability of traditional photovoltaic electricity generation is reduced; and the actual access rate of solar electricity generation is finally improved.
