Optimal Location And Sizing Of Distributed Generators In Distribution System.

This paper presents an approach for Distribution expansion planning by taking distributed generators into account. In order to supply electric power to consumers in a reliable and economic manner, distributed generators is considered to be one of the best solution. Distributed generators are also called on-site generators or dispersed generators. It generates electricity from small energy sources. DG has the advantages of power loss reduction, voltage improvement, increasing reliability, environmental friendliness. In order to reduce the cost and power loss of the system, DG unit size and location should be optimal. In this paper genetic algorithm is used as the optimization technique for finding optimal size and location of DG for reducing the power loss. To reveal the validity of GA standard IEEE 5 Bus system, 16 Bus system, and 30 Bus systems are examined.
