Adaptive MBPSS to Damp Electro Mechanical Oscillation of Grid Connected Microgrid

In the present work multi band power system stabilizers (MB-PSS) have been tuned by MDE-GWO and simultaneously employed to damp these electro mechanical oscillations of an AC micro grid. The grid connected AC micro grid consists up synchronous generator along with solar and wind sources. Electro mechanical oscillations may further excited by variation in solar and wind penetrations. The variations of solar and wind are taken in sudden and random manner with electric vehicle in different case studies. The modified Heffron Phillips model of this grid connected micro grid along with solar and wind sources been examined to impart electro mechanical oscillation in power system brought by variation in solar, wind sources and EV as load. The MB-PSS of the synchronous generators are tuned to damp these electro mechanical oscillations. The efficacy of MDE-GWO has been determined by comparing with both MDE and GWO.
