Analysis of Factors Influencing Photovoltaic Generators Optimal Installation in Distribution Network

The installed capacity generation and the load distribution effects on the optimal location and sizing of photovoltaic generators in the distribution network are analyzed in this article. A genetic algorithm estimates the optimal location and sizing of photovoltaic generators. The calculation of the feeder annual energy losses, which are the objective function of the optimization problem, is performed by the backward/forward method. The complete feeder's annual active load duration curve is segmented into three levels. It is assumed that the load curves in all buses are identical to the feeder and the irradiance and ambient temperature are invariant to the average value for each load level. The analysis is based on scenarios created for a 69-bus test system.
