A review on issues, challenges and various optimization techniques in microgrid

Abstract

A drastic change in the increase of carbon emission and green-houses gases has increased the demand of the use of Renewable Energy Sources (RESs). The integration of renewable energy in a power system network is due to the fact that the available natural resources are depleting at a faster rate. Microgrid with different configurations along with the development of smart grids ensures a paradigm shift from centralised to decentralized control. The installations done at the demand side of distributed generation marks change in the forthcoming years in the electricity markets both at the generating and distribution end. With the introduction of Microgrid the hedging of investment is done in different sectors of the electric industry such as generation operations, etc., easily. This review paper gives an idea about fundamental definition of a Microgrid (MGs); classification of Microgrid, issues, and challenges associated and optimization techniques for the overall stability and security of the grid.
