Analysis of Energy Management in Micro-grid with Distributed Generation System

The Energy management in Micro-Grid system is one of the most irrefutable issues in micro grid technology development. The Micro grid energy system consists on non-conventional resources, unit with storage energy and islanded or grid connected mode of operating loads. This tabloid presents a Micro-Grid energy management system for distributed generation connected MG with hybrid energy storage system. Hybrid energy storage system is achieved by combining the Ultra-capacitor and battery storage. The proposed energy management system in micro grid with hybrid energy storage system follows the two techniques, such as forecasting and optimization. Prediction of solar irradiance, load demand and temperature are coming under the Forecasting technique. For the economical operation in a grid connected micro grid the optimal day-ahead scheduling of power generation and load demand is performed by the optimization technique. The MG will absorb or deliver the prespecified amount of power. In this method MG connected to the power grid in large numbers are integrated. The main intension of the energy management system is power balancing in the micro grid. The MATLAB/Simulink environment has been used to analyzing the effect of Energy management in micro-gird with hybrid energy storage system. The simulation results will show the effective and stoutness of the proposed energy management method.
