Role of Multi-Band Stabilizers on Grid Connected Microgrid

With the increase in demand of electrical energy, there is a need of an environment friendly generation. With the conventional energy generation systems various environmental and economical issues are concerned. In order to have an economically and environmentally beneficial generation, Microgrids have been introduced. A microgrid basically comprises of various DERs and various renewable energy sources to feed its loads. In this work various different types of power system stabilizers (PSSs) like CPSSs Delta Omega Power system stabilizer and Delta Pa PSS, multi-band PSS (MB-PSS4B and MBPSS-2B) have been compared in controlling the grid connected microgrid. With the help of different PSS's the stability and active - reactive power contribution of different DERs have been controlled. In this paper, Matlab/Simulink software is adopted to simulate an AC microgrid using different control strategies.
