Energy management in DC microgrid

Microgrid is the combination of distributed energy resources (DER), distributed storage (DS) and load. The growing need of electrical energy can be fulfilled by harnessing energy from renewable energy sources (RES) along with conventional sources of energy. By understanding need of electricity and available energy sources and storage, energy management can be done. The task of EMS is to manage the energy between source and load. This paper presents the simple model of dc microgrid with energy management system. The simulation model is developed in MATLAB/Simulink containing photovoltaic array, wind turbine generator (PMDC generator), battery storage, grid and energy management block. The simulation results are presented with variable load and variable generation conditions.
