On the optimal design of wind-solar hybrid power system

A mathematical model for the optimal design of wind solar hybrid power system is presented in this paper.The object of the model is to minimize the initial investment cost with performance indices as constraints so that the optimal matched power and optimal control strategy can be found between turbines, solar cell arrays, batteries, diesels, inverters and loads. A practical example is calculated by using the model. The results show that the optimal design rules for the wind solar hybrid power system are quite different from those for the stand alone photovoltaic power system.So the optimal design rules for the wind solar hybrid power system is worth being studied further.
