Design of Filters for Power Quality Improvement in Microgrids

Abstract:

This paper deals with the design of filters for power quality enhancement in microgrid. The voltage source inverters (VSI) fed from microgrid requires filter across them to detect the unbalance and harmonics in the system. The performances of various filters are compared and the improved negative sequence filter is found out to be the best solution. The stability of these filters are also studied and simulations are carried out to validate the results.
