Optimal Location of STATCOM for Voltage Security Enhancement via Artificial Intelligent

Voltage security is a crucial issue in power systems especially under heavily loaded conditions. In the new scheme of restructuring, voltage stability problem becomes even more serious. Due to the increase of stability margins, FACTS devices are the options to mitigate voltage instability by reactive power flow and voltage control criteria. The main purpose of this paper is to identify the optimal location of Static Synchronous Compensator (STATCOM) to enhance power system voltage security by using an artificial intelligent technique. The proposed method demonstrates the improvement of voltage security margin. It is implemented to a modified IEEE 14-bus system.
