Real-Time Frequmency and Voltage Control of an Islanded Mode Microgrid

In this paper, we investigated the necessity and effects of optimal control methads in the stability and performance of a micro-grid that operates in is landed mode. The micro-gird is consisted of a combine heat power (CHP), a capacitor bank (CB), photovoltaic panel (PV) as power generation sources. In addition, battery and the building electritiy and thermal load are placed on the load side. A simple comprehensive model is assumed for each component of the micro-gird and the dynamic behavior of micro-grid voltage and frequency is studied in details. Since the micro-grid operates in islanded mode, the fluctuations in the buillding load act as disturbanced and could cause the instabilitiy in the voltage and frequency. So it is necessary to design a controller to regulate the voltage and frequency. Particle swarm optimization (PSO) is used as a method to realize the optimal controller in the micro-grid. Simulation resultuctuations.s showed the effects of proposed controller on the reduction of voltage and frequency fl
