Abstract

To meet the demand for rapidly growing load and reliably power supply from the consumer, the joint operation of distributed generation (DG), possessing advantages of saving investing and flexibility, with power grid brings tremendous variation for modern power system in economy and environment. But applica-tion of individual distributed generators can cause as many problems as it may solve. A better way to realize this is to take a system approach which views generation and associated loads as a microgrid. The microgrid concept assumes a cluster of loads and microsources operating as a single controllable system that provides both power and heat to its local area. This concept provides a new paradigm for defining the operation of DG. After concluding the research of DG and microgrid, this paper discussed the key problem, relevant references and expectation of distributed generation and microgrid.
