Power Management Strategy and Control of Islanded DC Micro-Grid System

This article demonstrates power management and controlling strategy for proposed Islanded DCMG system, based on solar PV, PMSG-WECS, fuel cell, and battery storage systems. PV and wind usually use maximum power point tracking (MPPT) for delivering continuous power to load under solar insolation and wind speed variation. The DC microgrid connects to loads of resistive load and constant power load (CPL). Proton Exchange Membrane Fuel cell (PEMFC) delivers continuous power to load during the unavailability of solar and wind. The energy management strategy proposed and results are presented based on the MATLAB-Simulink.
