전력제어시스템은 외부망으로부터 보호하기 위하여 망분리를 해야 하지만 부득이하게 외부망과 연결을 필요로한다. 이러한 이유때문에 망연계 구간에서 보안을 강화할 수 있는 다양한 보안솔루션들이 개발되고 있다. 이 논문에서는 제어시스템에서 사용하고 있는 PI시스템과 제어망으로의 접속을 원천적으로 차단하는 물리적 일방향자료전달시스템 연계를 위한 구성과 그에 따른 에이전트 구현방법을 소개한다.

This study examines the determinants of net export of electricity among 30 European countries sharing electricity grid during the period of 1990~2014 by separating the sample period before and after 2005 in which ETS was introduced in Europe. The empirical method used in this study is generalize least squared one considering both heterogeneous and serial correlation in the balanced panel data. According to the empirical results, after 2005 introducing the ETS, holing energy resources, concentrating only on few electricity generation resources, and nuclear electricity generation had played more important role in net export of electricity, while renewable energy had negative effect on net export of electricity and coal and gas generation have no effect on net export after introduction of ETS in Europe probably because of high environmental cost. The policy implication of the results would be that reconsidering each country's optimal generation mix strategy and its role in case freely trading electricity.
