Abstract

In this paper, we present a smart grid monitoring system connected with electric vehicle charging system using anti-islanding method. Electric vehicles can be charged through remote control of smart grid monitoring system and the charging process may be more stable and more efficient by wireless communication between the Local Area Module and End Modules. It is illustrated by some experiments that electric vehicle charging process may not be interrupted without any serious fault even though the islanding phenomena occurred in the grid if the presented monitoring system was applied to the smart grid system.

본 논문에서는 무선 센서 네트워크를 활용하여 스마트그리드와 전기자동차의 충전 시스템 연계과정을 효과적으로 파악하고, 안티아일랜딩 기능을 적용하여 전기자동차 충전계통과 연계된 스마트그리드 모니터링 시스템을 제안한다. 스마트그리드 모니터링 시스템은 지그비(ZigBee)통신을 통해 무선으로 전력 모니터링 데이터를 수신하며, 별도의 물리적 연결 없이 원격 제어를 통해 전기자동차의 충전제어가 가능하다. 또한, 그리드 내 독립전원에 아일랜딩 현상이 발생하면, 아일랜딩 현상이 발생한 독립전원을 즉시 감지하여 차단하고 다른 독립전원으로 대체하여 그리드의 안정적인 운용을 하도록 하며, 실험을 통하여 스마트그리드 모니터링 시스템의 성능을 확인한다.
