Modelling and Simulation of DC microgrid

Abstract

DC microgrids have permeated the energy market in recent years due to the achievement of higher efficiency outputs during power distribution as compared to AC microgrids. Current DC microgrid technology relies on renewable energy sources (e.g. photovoltaic panels, wind turbines) and sub-systems to attain high efficiency while facilitating maximum power point tracking (MPPT) among charge controllers. The key component of a microgrid system is its energy storage system, which assists in mitigating power intermittency due to the deployment of renewables. This paper emphasizes on energy management and control of a DC microgrid system, whereby a simulation model of the proposed DC microgrid is developed in MATLAB/Simulink environment for electrification of a small town. The acquired simulation results have demonstrated feasibility of the proposed DC microgrid during operations.
