초록

전력산업의 구조개편과 더불어 분산전원의 배전계통연계운용 및 전력품질이 전력회사의 배전사업자, 구역전기사업자, 전기공급 신뢰도와 밀접한 관계에 있는 산업용 수용가들에게 많은 관심을 불러일으키고 있다. 이러한 주변정세는 차세대의 배전계통이 다수의 Micro-grid들로 구성될 것이라고 하는 예상을 전문가들로부터 제기되기에 이르렀다. 그러나, 제안된 Micro-grid는 몇몇의 분산전원과 전력품질을 보상하는 기기, 그리고 통신제어설비와 부하들로 구성된다는 기본적인 내용에 지나지 않는다 따라서, 본 논문에서는 수용가에 고신뢰 고품질의 전력공급을 가능하게 하는 차세대 전력공급네트워크인 Micro-grid의 적정전압유지를 위한 자율분산협조 운용제어 알고리즘을 제안한다.

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.
