Reactive Power Contribution of Multiple STATCOM using Particle Swarm Optimization

S. Uma Mageswaran, Dr.N.O. Guna Sekhar

Abstract


Reactive power is vital for reliability, power quality, transmission line loss and voltage stability. Rapid industrial development makes the power system is stressed. This stressed power system has more loss and low voltage profile, generator has its limitation and could not generate sufficient reactive power, to overcome this situation Flexible AC Transmission System (FACTS) devices are used. This paper makes use of one such FACTS device namely STATCOM to relief power system stress by injective adequate reactive power. Particle Swarm Optimization (PSO) technique is used to optimize the STATCOM location and reactive power injection. PSO algorithm provides best location for the STATCOM and amount of reactive power to be injected in the location. In this papers first only one STATCOM is connected then two STATCOM and finally three STATCOM are connected to the system to know best number of STATCOM to be connected and best location and amount of reactive power injection. Test case IEEE-30 bus system is considered for the simulation.

Keywords
