Abstract

The invention discloses a photovoltaic power generation current-stabilized energy supply method. The method comprises the following steps: electric energy of a photovoltaic power generation unit is converted to mechanical power; air is liquefied by the mechanical power to obtain liquefied air; the liquefied air is stored in a liquefied air storage tank; the liquefied air is provided to a heated fluid channel of a heat regenerator by the liquefied air storage tank to obtain pressure compressed air; the pressure compressed air is led into a combustion chamber, so that a working medium is obtained by a combustion chemical reaction between the pressure compressed air and fuel in the combustion chamber; the working medium is led into a turbine with more than two stages; the turbine pushes a generator to outwards output electric power; and the working medium discharged by the turbine is led into a heating fluid channel of the heat regenerator. The invention further discloses a photovoltaic power generation current-stabilized energy supply system. As the electric energy of photovoltaic power generation converts air into liquefied air and the liquefied air is stored in the liquefied air storage tank, the problem of instable energy supply caused by the weather factor can be solved.
