  • Interconnection of DG(Distributed Generation) into distribution systems and power quality are frequent subjects of discussion by distribution companies, regional electricity utilities and industrial customers. This situation makes many experts estimate a next generation of distribution systems which is composed of some micro-grids. But the proposed micor-grid is only mentioned as a small network with DG's, power quality compensators, communication and control equipments. In this paper, a decentralized coordination control algorithm of micro-grid which is able to supply the electric power with high reliability and quality, are proposed.

  • The concept of the Micro-Grid comprising Micro-Sources supplying both heat and power ranging from several [KW] to 1[MW] to local customers is proposed by CERTS(Consortium for Electric Reliability Technology Solutions). Micro-Sources adopt environmentally friendly and reliable power sources such as Fuel-Cell and Micro-Turbines. Micro-Sources adopt voltage source inverter with AC grid system in order to provide independent real and reactive power control for premium power quality. Thus Micro-Source needs series inductance for interfacing with AC grid system. With this reason, we propose a technique that can decide the optimal size of the inductor for effective transfer of the power into the grid.
