Solar energy and wind energy are widespread,and they are two types of renewable energy which are easy to obtain.In wind&solar hybrid power systems,how to make full use of the two types of renewable energy and meet the requirements of power flow in the systems is critical in practical applications.In this paper,through power flow analysis of the wind&solar hybrid systems with battery in two operation modes,the corresponding energy control strategy and implementation method as well as the work state switching logic are given.These ensure the maximum use of electric power from the renewable energy systems and the reliable power supply to loads.
