The paper presents variable structure simulation models for wind-solar hybrid power systems(WSHPS), including the hardware configurations of the power system and the calculation of output power of all system components. On the basis of the models, the software has been developed under C++ builder environment. A calculating example of WSHPS is provided. The results show that by the use of this software, the operation of the WSHPS with various structures can be simulated so that the main performances can be predicted, such as the matching degree between PV Array, wind generator, battery and loads, the rationality of control strategies, the system efficiency and so on.
