This paper presents the development of gateway for smart grid for the interoperable communication between IEC 61850 station leveled devices and one of legacy Modbus, DNP3, and IEC60870-5-101/104/103 communication protocol devices of bay level in substation or for the exchange of information between IEC 61850 substation and SCADA control center. The data-mapping model is designed for the exchange of information and the gateway configuration tool is developed for generating meta-data based on XML Schema. this paper is mostly concerned with the design and realization of gateway system for the interoperable data communication between a legacy protocol device and IEC61850 based devices or systems.

Demand for distributed source by new and renewable energy has been gradually increasing recently. For the characteristics of distributed generation, distributed source is located near the distribution system and customers' buildings and can be operated in standalone mode or in interface mode with distribution system. When the distributed sources are interfaced with distribution system, the standard for interfacing distributed source with existing distribution system and operation manual should be updated with revisions in order to manage the distributed source effectively and operate the distribution system stably because how to operate the interfaced system is different from that of existing distribution system. In this paper, the FEP(Front End Processor) using the international standard protocol IEC-60870 for interfacing with distributed resources was designed. The designed system was verified via the test result using main control system for distributed generation and RTU(Remote Terminal Unit) for interface with distributed power generating.

현재 서부아프리카 지역의 경우, 대부분의 발전원은 수력과 화력에 의존하고 있으며 서부 아프리카경제공동체(ECOWAS) 15개 회원국의 전력수급률은 매우 낮은 수준일 뿐만 아니라 국가별 에너지 불균형 또한 심한 상태이다. 이에 서부 아프리카 전력공동체(WAPP)는 지역 간 에너지 불균형 해소 및 국가 간 전력망 연계를 위한 전력거래센터(ICC)의 구축을 추진하고 있다. 본 논문은 향후 WAPP ICC에서 본격적인 전력거래기능을 수행하기에 앞서 각 지역제어센터(CAC)의 전력 정보 수집, 분석 및 공유를 위한 자료연계 방안에 대해 서술하였으며 센터간의 자료연계를 위한 통신 프로토콜은 IEC 60870-6(ICCP) 프로토콜을 이용하였다.
