Abstract—This paper proposes the meaning and essentiality of developing the hybrid power generation system with wind turbine, photovoltaic and electric storage, and expatiates the basic principle of the system. Then, this paper discusses the key technology of Wind-PV-ES ratio optimization algorithm, hybrid power generation system optimization integration, power estimation, integrated monitoring, and maintenance. Finally, the development and application outlook of the system in China is analyses and proved.

Index Terms—Wind-PV-ES, hybrid power generation, system optimization integration, integrated monitoring.
