Comparative analysis of SRF based Shunt Active Filter using Grey Wolf and Eagle Perching Optimization

Power electronic devices play a vital role in manufacturing process, research and development because it provides high efficiency, low cost, rapid operation, and optimal size of the system. In recent years, power electronic devices have become widely employed in a variety of fields. Application of power electronic devices leads to harmonic generations which have a substantial impact on power systems. The main sources of harmonics are nonlinear loads and energy conversion devices such as static converters, choppers, cyclo-converters, battery charging systems and heating elements etc. To reduce harmonics, different kind of filters are introduced, shunt active power filter is one of the most significant and effective filter. In this research the performance of a shunt active power filter based on synchronous reference frame theory is described and it is tuned for significant performance employing Grey Wolf Optimization and Eagle Perching Optimization techniques.
