The optimal dispatching research of the wind-hydro hybrid system

To improve the operation benefit and power output characteristics of a wind farm, and fully use the wind energy resources, the way using wind-hydro hybrid system can be adopted where there are some water resources to enhance the power quality and operation benefit of wind park. Considering the difference of peak and valley electricity prices in the electricity market, this paper rationally use the index of minimizing the wind power output fluctuation and maximizing the wind park operation benefits, and establish the Benefit-Gauss model ( i.e. ,B-G model) to optimize the dispatching of wind-hydro hybrid system. The model is executed for a typical operating condition of wind park by a refined genetic algorithm using probability search and local elastic search.
