Effect of Distributed Generation on Economical and Environmental costs of Electrical Networks

Abstract

This paper aims to study the influence of D. G. implication on the power loss in Electrical Distribution Networks of 20 KV.

A P. V. system is taken as D.G. in the considered Distribution Network.

To calculate the power loss in Electrical Distribution Networks, the power flow in the network lines must be known, so it is necessary to use a suitable algorithm that can calculate the power flow and consequently the power loss in the Distribution Network for both cases: before and after the D.G.(P.V.) implication.

A part of Damascus Suburbs network is considered a case-study.

The effect of P.V. placement and its penetration ratio on the loss reduction are also investigated.
