Voltage and Frequency Control of Microgrid Systems with Demand Response.

This paper describes and present the operation of a microgrid comprising photovoltaic, fuel cell and battery bank. Photovoltaic cells represent variable resources and fuel cell represent dispatchable resources. All these sources are coupled to grid through power electronic converter. The inverters are controlled by a decoupled control method. The frequency and voltage inside this Microgrid is controlled by performing fast demand response. The Microgrid and simulation study are performed in MATLAB/SIMPOWERSYSTEM. The simulation results show that fast demand response is capable in controlling the voltage and frequency inside a Microgrid. [ABSTRACT FROM AUTHOR]
