The application of phase change energy storage technology in the utilization of new energy can effectively solve the problem of the mismatch between the supply and demand of energy in time and space, and significantly improve the utilization rate of new energy. This paper mainly studies the application progress of phase change energy storage technology in new energy, discusses the problems that still need to be solved, and propose a new type of phase change energy storage - wind and solar hybrid integration system. The advantages and disadvantages of phase change materials are compared and analyzed. Summary of the application of phase change storage in photovoltaic, light heat, PV / T and wind energy, and the principle of operation of phase change energy storage - wind and solar hybrid integration system is introduced.
