Application of microgrid in distributed generation together with the benefit research

Microgrid technologies are highly developed in low voltage networks, improving the power supply reliability and energy efficiency. Therefore, in this paper, the concept, including the configuration, principle and operation of microgrid, will be specified, comparing the microgrid with the prior distributed generation. Additionally, in order to justify the feasibility, the economical benefit analysis of the application will be identified via some methodological viewpoints which are advised to regulate the operation of the microgrid in an economical approach. At the end, the costs, benefit and the share of the microgrid and micro-generation are discussed by analyzing the test case.
