In order to make better use of wind resources and reduce abandoned wind and improve capacity of grid accepting wind power ,this paper studies the feasibility of storing abandoned wind based on using the PHS(Pumped Hydro System). The paper has constructed model of Wind – PHS co-generation system based on operating characteristics of various types of power. Under the constraints of system demands and the technical characteristics of various types of power, the model use the minimum total operation cost of the system as the objective function, then use real coding genetic algorithm simulation to solve the problem. The results show that the use of pumped storage power station can not only reduce the abandoned wind, and the economic benefits of storage abandoned wind are better than the economic benefits of without wind abandoned. At last with evaluation and factors influencing the analysis, the conclusion that the optimal capacity of pumped storage power station in the system is expected to providing a reference which can help for the rational allocation of resources. |
