Introduction: The microgrid system comprising of small-scale distributed generation system and loads can be promptly incorporated by means of the renewable energy sources [1-2]. Numerous researches have been conducted on the microgrid notion [3-5]. The performance of microgrid system is complex and irregular while some microsources are associated. In order to understand the behavior of a microgrid with several microsources, key issues such as microgrid control, stability and protection have to be considered in detail. Background: The increasing require of electricity, fast exhaustion of fossil fuels, diminution of CO2 emissions, in conjunction with the incapability and ineffectiveness of present electricity grid are motivating chief changes in electricity production, circulation and consumption guides around the globe. In recent times, smart electricity grid configurations comprised with interlinked small or medium dimension generators, energy storage elements as well as power electronic technologies have been germinated to find the key limitations of the conventional grid structure. Microgrids are major ingredients of these promising grid configurations. Even though microgrids are received as feasible solutions to power stability and quality topics in ac power systems, the ambiguity in the capacity of microgrids are to deal with serious changeable load and fault situation is the most important pertain in the function of these novel grid confi gurations. In the previous decennium, enormous attentions were elevated on the subject of distributed generation units, for instance solar photovoltaic panels, wind turbine generators, fuel cells, and so on. These Distributed Generations ... ...bjectives: The focus of this research proposal is to develop of a microgrid management system for reliable operation which will be incorporated with modeling, controlling, and power management of microgrid applications. Toward this proposal a theoretical investigation of the basic function of a feeble grid will be presented. A novel grid management strategy under changeable loads will be proposed for power management. Simulation work and experimental test will also carry out to demonstrate and validate the proposed control system for the operational improvement of the DG networks. The main objectives of this research project can be described as †¢ Development of novel control techniques, flexible and advanced, for system control improvement in a feeble power system. †¢ Improvement of power conversion efficiency. †¢ To examine how a feeble power system can be built up
