Abstract
Flexible Alternating Current Transmission System (FACTS) devices are the best option to solve the voltage instability by reactive power flow and voltage control criteria. Among various FACTS controllers, in this paper we have considered Static Synchronous Compensator (STATCOM). Main objective is to find an optimal rating of STATCOM for minimization of reactive power loss and improve power system performance.We have used the Genetic Algorithm(GA) and Newton-Raphson method to find the optimal rating of STATCOM. To verify the effectiveness of algorithm, studies are carried out on IEEE-33, IEEE-30 and IEEE-9 bus systems with different loading conditions.
A program in MATLAB is developed for the purpose of calculations.
Keywords
STATCOM, genetic algorithm, Newton Raphson method.
