A Comprehensive Review on Energy Management in Micro-Grid System

Abstract

Since the last decades there has been a huge exploitation of non-conventional (renewable) energy resources which has increased significantly. A Micro-Grid (MG) presents an appropriate concept to integrate local resources of renewable energy with Storage System of Energy (SSE) and are synchronized to supply the customers' requirement in different circumstances. Apart from this, the Management System of Energy (MSE) has been analyzed for allocating the output power from the Distributed Generator (DG) units optimally. It also satisfies the local demand, regulates the voltage and frequency of the smart MG, and secures a flat switching between modes, connected to grid and mode of islanded operation. In this article the authors have made an outmost effort about the area of MG–MSE, evolved in the current framework, discussing the storage units and generation of MG, the importance of Electric Vehicles (EVs) as a backup unit, combined heat and power for supplying the thermal requirements, objectives function of MG-MSE and constraints of the systems and current algorithms of optimization. © 2021 Scrivener Publishing LLC.
