An Intelligent PI Controller-Based Hybrid Series Active Power Filter for Power Quality Improvement

The quality of power that is degrading day by an important issue for all the consumers. factor this harmonics in voltage and current waveforms which can be resolved use hybrid series active filter. combination consists a filter shunt passive connected parallel to load. method used paper purpose achieving good harmonic compensation reduced total distortion various types nonlinear loads as per standards IEEE 519. proposed HSAPF technique uses synchronous reference frame generating compensating signal with intelligent PI controller particle swarm optimization (PSO) obtain required gain values needed improve steady state response system. concept vigorous has been authenticated through MATLAB simulation analysis, results obtained validate accuracy different load conditions.
