VOLTAGE STABILITY ENHANCEMENT BY OPTIMAL PLACEMENT OF STATCOM USING GENETIC ALGORITHM

Voltage security is a crucial issue in power systems especially under heavily loaded conditions. In the new scheme of rearrangement, voltage stability Issue becomes even more serious. Due to the increase of stability margins, Flexible Alternating Current Transmission System (FACTS) devices are the alternatives to mitigate voltage instability by reactive power flow and voltage control criteria. The main purpose of this paper is to identify the optimal Placement of Static Synchronous Compensator (STATCOM) to increase the power system voltage profile using Genetic algorithm. The proposed method established to improvement of voltage security margin. It is implemented to a modified Sample 5-bus system.
