To address the increasing complexity of demand, conventional grids are incorporating communication technology like advanced metering with sensors, demand response, energy storage systems, and electric vehicles. Microgrids are proposed to maintain local energy balance and reliability, providing resilient operation and intelligent energy management techniques to control power exchange. This paper gives an overview of microgrids, their operations, energy management approaches, and the key role of energy management systems in maintaining balance and contributing to profit.
To sustain the complexity of growing demand, the conventional grid (CG) is incorporated with communication technology like advanced metering with sensors, demand response (DR), energy storage systems (ESS), and inclusion of electric vehicles (EV). In order to maintain local area energy balance and reliability, microgrids (MG) are proposed. Microgrids are low or medium voltage distribution systems with a resilient operation, that control the exchange of power between the main grid, locally distributed generators (DGs), and consumers using intelligent energy management techniques. This paper gives a brief introduction to microgrids, their operations, and further, a review of different energy management approaches. In a microgrid control strategy, an energy management system (EMS) is the key component to maintain the balance between energy resources (CG, DG, ESS, and EVs) and loads available while contributing the profit to utility. This article classifies the methodologies used for EMS based on the structure, control, and technique used. The untapped areas which have scope for investigation are also mentioned.
