In modern era, the awareness of green energy technologies in the Microgrid (MG) is highly adopted in order to reduce the CO2 emission and for a clean environment. The distributed energy resources, such as solar photo voltaic (PV), solar combine heat and power (CHP), diesel engines, small wind turbines and fuel cell technologies are evolving within the power system. The control and maintenance of this power have great effect on power systems. For optimal use of electric power in MGs, the Multi-Agent System (MAS) technology is adopted and has certain applications in the power systems. This research article mainly focuses on MAS technologies used for the control of MG, its optimization and market distribution. A fully controlled architecture of MG using MAS with different optimization techniques applied to renewable energy sources has been deliberate. Moreover, comparison of centralized and decentralized approach of a MG is also discussed in this article.
