Optimal placement of static var compensators in power system for stability improvement

Abstract

This paper presents a new method which applies the application of Genetic Algorithm as meta-heuristic optimization method for power system problems in distribution substations. With increase in load, any power system model suffers from disturbances. These disturbances effect the overall stability of the system. Criterias like voltage profile, power flows, losses tell us about the state of the system under study. Load flow analysis under study is capable of providing the insight of the system. Static var compensator is one of the methods and can be applied to obtain a system with least losses, increased power flow and healthy voltage profile. Number, location and size of Static var compensator are the main concerns and they can be optimized to a great extent by Genetic Algorithm. Use of Static var compensator in system has shown considerable increase in voltage profile and power flows while decrease in losses.
