Abstract

This study is the central axis of the MG (Micro-Grid) configuration and it has the link through the modular hybrid power source and the DC bus, and it provides the function to detect and block the illegal connection by using the standard socket, And to achieve stabilization. Development of power conversion device, smart distribution panel, integrated control system and efficient demand management are required, and compatibility with MG whole system is urgent. This is a hybrid power generation system that is safe with a common power connection protocol and can be easily connected to anyone. This makes it easy to manage data and prepare for expansion of various manufacturers' systems.

본 연구는 스마트분전반 MG(;Micro-Grid) 구성의 중심축으로 모듈형 하이브리드 발전원과 DC버스를 통하여 링크를 갖으며 표준소켓을 사용하여 불법연결을 감지 차단하는 기능을 부여하고, 전력계통의 안정화를 달성함을 목적으로 한다. 전력변환장치, 스마트분전반, 통합제어시스템의 개발과 효율적인 수요관리가 필요하며, MG 전체시스템과의 호환성이 절실하다. 이는 공통 전력 연결 규약으로 안전하고 누구나 연결을 쉽게 할 수 있는 하이브리드발전시스템으로 데이터 관리가 용이해지고 다양한 제조사의 시스템 확대설치에 대한 대비가 가능하다.
