Abstract

There are many types of power facilities such as transformers, switches, and energy storage devices in the micro grid environment. However, with the development of IoT technology, opportunities to acquire sensor information such as temperature, pressure, and humidity are provided. In the existing micro grid environment, the communication protocols such as MMS transport protocol in IEC 61850 standard is applied in accordance with the integrated operation between the power facilities and the platform. Therefore, to accommodate IoT data, a gateway technology that can link IoT data to a data collection device (FEP) based on IEC 61850 is required. In this paper, we propose IEC 61850 based IoT gateway platform prototype for microgrid operating system linkage. The gateway platform consists of an IoT protocol interface module (MQTT, CoAP, AMQP) and database, IEC 61850 server. For databases, We used open source based NoSQL databases, Hbase and MongoDB, to store JSON data. We verified the interoperability between the IoT protocol and the IEC 61850 protocol using Sisco's MMS EASY Lite.

마이크로 그리드 환경에는 변압기, 스위치, 에너지저장장치 등 많은 종류의 전력 설비가 존재하지만, IoT 기술의 발달에 따라 온도, 압력, 습도와 같은 센서 정보를 취득할 수 있는 기회를 제공하고 있다. 기존의 마이크로 그리드 환경에서는 IEC 61850 표준에서 정의하고 있는 MMS 등의 통신 프로토콜을 준용하여 전력 설비와 플랫폼 간 통합 운용되고 있다. 그렇기 때문에 IoT 데이터를 수용하기 위해서는 IEC 61850 기반으로 구성된 데이터 수집 장치(FEP)에 IoT 데이터를 연계해 줄 수 있는 게이트웨이 기술이 필요하다. 본 논문에서는 마이크로그리드 운영 시스템 연계를 위한 IEC 61850기반 IoT 게이트웨이 플랫폼 프로토타입을 제안하고자 한다. 게이트웨이 플랫폼은 IoT 프로토콜(MQTT, CoAP, AMQP) 인터페이스 모듈과 데이터베이스, IEC 61850서버로 구성되어 있다. 데이터베이스의 경우, JSON 데이터를 저장하기 위해 오픈소스 기반의 NoSQL 데이터베이스인 Hbase와 MongoDB를 이용하였다. IoT 프로토콜을 검증하기 위해 라즈베리파이 아두이노 인텔 에디슨 SoC 기반 전력 IoT 디바이스 시뮬레이터를 이용하였고, IEC 61850은 Sisco's MMS EASY Lite를 이용하여 IoT 프로토콜과 IEC 61850 프로토콜간의 상호호환성을 검증하였다.
