Microgrid architecture, control, and operation

Abstract With increasing concerns over environmental impact of conventional methods of power generation, thrust is shifting towards renewable energy generation schemes. Renewable energy solutions such as solar, wind, and other methods are commercially grown up and are being harnessed individually for electric power generation. The new challenge is to accommodate these small-sized renewable energy sources into existing power network. Search for suitable architecture and control schemes is an important area in research, with several people working to find an appropriate solution. AC, DC, and AC–DC hybrid microgrid are some of the architectures proposed in literature. With multiple renewable energy sources providing electrical energy simultaneously, the load sharing among different sources has to be controlled according to the individual capacities of sources. Both communication-based and without communication power sharing control schemes are proposed in literature.
