Reliability Planning of Distributed Generation Considering Wind Power Fluctuations

In order to guarantee the scientificness and reliability of the distributed generation planning,the study for the siting and lectotype of distributed wind power is carried out. Weibull distribution is used to describe the characteristic of change in wind speed distribution,and combiming with the power curve equation of wind turbine the power output fluctuations model is built in this paper. And a cost model of fluctuations of distributed wind power is built on this basis. Based on minimizing the system cost,optimization scheme is proposed in order to provide the theoretical basis for sitting and lectotype of distributed wind power. According to situation analysis,it shows that the model and the optimization scheme can provide scientific theoretical basis for the sitting and lectotype of distributed wind power.
