Reactive power control by using capacitors and implement the method of PSO

Reactive power control is a very essential and necessary strategy to maintain the safe and reliable operation of power systems. There are different methods available for optimization of reactive power. In spite of the advantages of power electronic devices, placement of the capacitors still remains technically viable and an economically affordable option for reactive power control. In this paper we have proposed a method of reactive power control by optimum sizing of capacitor with the help of particle swarm optimization. In this work we have presented a method to reduce the reactive and active power losses by having a coordinated and constrained optimization approach. To validate the proposed approach an IEEE 30 bus, test bus considered. At tool in the form of Graphical User Interface is also presented as part of this work.
