MICROGRID is one of the new emerging power distribution infrastructures with prominent potentials... more MICROGRID is one of the new emerging power distribution infrastructures with prominent potentials in modern civilization. The concept of microgrid has the potential to solve major problems arising from distributed generation in distribution systems. Microgrid is defined as the cluster of multiple distributed generators (DGs) that supply electrical energy to consumers without any shortage [1]. Renewable energy resources are becoming the fastest growing segment of the energy industry in which the technical issues and environmental impacts have to be studied and understood. According to the latest Indian scenario the grid losses from the transmission to the distribution system alone are 20-40% [2]. In remote villages and rural areas where grid connection is insufficient, the large number of small-scale components with their own characteristics is a big challenge for Microgrid modeling and planning. Especially in term of renewable energy, the power output might be seasonal and non-dispatchable. Microgrid plays an important role in utilization of renewable energies such as PV arrays, fuel cell and wind turbines [3]. A powerful simulator engine called HOMER developed by the U.S. National Renewable Energy Laboratory (NREL) to assistant in the design of micro-source systems to facilitate the comparison of power generation technologies across a wide range of applications. HOMER models a power system’s physical behavior and its lift cycle cost, which is the total cost of installing and operating the system over its life span. HOMER allows the modelers to compare many different design options based on their technical and economic merits. It also assists on understanding and qualifying the effects of uncertainty or changes in the inputs. To enhance renewable energy resources a case study of a Wind- PV-Diesel hybrid microgrid system with battery storage is built in HOMER to test and analyse. A powerful simulator engine is necessary to overcome these challenges.

The concept of microgrid has the potential to solve major problems arising from distributed generation in distribution systems. Microgrid is defined as the cluster of multiple distributed generators (DGs) that supply electrical energy to consumers without any shortage. The realization of demand response, efficient energy management, high capability of Distributed Energy Resources (DERs), and high-reliability of electricity delivery leads to a successful microgrid. In a microgrid network, total maximum load matches to the generated power. Large growth in electricity consumption and rise in number of sensitive or critical loads leads to increase in demand of electricity in daily life. A proper control strategy should be implemented for a successful operation of a microgrid and in utilization of renewable energies such as PV arrays, hydro, thermal and wind turbines. In this technical context an overview of microgrid has been carried out based on the reports from the literature present in past two decades.
