Reactive power compensation by EPSO technique

2010 IEEE International Conference on Systems, Man and Cybernetics, 2010
This paper presents a methodology to address reactive power compensation using Evolutionary Particle Swarm Optimization (EPSO) technique programmed in the MATLAB environment. The main objective is to find the best operation point minimizing power losses with reactive power compensation, subjected to all operational constraints, namely full AC power ...

Dynamic reactive power compensator (DRPC) for unbalance load reactive power compensation

2013 IEEE 8th International Conference on Industrial and Information Systems, 2013
Unbalance in power system caused by the addition of single phase and dynamically varying loads are unavoidable. Due to this reason the load reactive power is no longer balanced, which causes voltage fluctuation, line overloading and high transmission line losses.

Clean reactive power compensator

IEEE 2002 28th Annual Conference of the Industrial Electronics Society. IECON 02, 2003
New method is proposed to compensate reactive power of fundamental current component. New clean reactive power compensator CRPC is presented. True sinusoidal voltage wave inverter is connected to the supply system through inductance. Connection to supply system by natural shaped voltage source does not produce additional distortion.
