2030년까지 한국에 Smart Grid를 구축할 계획을 가지고 추진하고 있다. Smart Grid는 지능형 전력망으로 기존의 전력망에 IT를 접목시켜 통신을 실시하여 양방향성을 가지게 된다. 기존의 전력망에 부가될 IT전기기기들은 기존에 IT가 지니고 있는 취약점들이 있어 기존의 Smart Grid공격에 노출되어 있다. 본 논문에서는 한국보다 먼저 구축되어서 활용되고 있는 미국의 Smart Grid에 대한 공격사례를 분석한다. 그리고 한국 Smart Grid에 대한 전기IT기기의 취약점을 분석하여, 한국 Smart Grid에 대한 예상 공격을 분석하고, 보안 대책을 제시한다. 본 논문은 한국 Smart Grid에 안정성과 보안성을 갖춘 기술 자료로 활용할 것이다.

Five smart grid projects was started with large scale at Jeju Island in South Korea from 2009, and smart-grid test-bed was started in Nov. 2010. The five projects are Smart Power Grid (SPG), Smart Renewable (SR), Smart Transportation (ST), Smart Place (SP) and Smart Electric Service (SES). Korea government constructed the smart grid public relations center at Nov. 2010 in Jeju Island and there will be continued the field operation and interface testing among five smart gird projects until May. 2013.

Recently, there is a rising interest in smart grid operating system which manages various types of distributed generation, smart meters, and electric vehicles with power grid. Considering the features of smart grid environment, the interoperability should be one of the important factors to build smart grid environment successfully. To secure interoperability, smart grid operating system should conform to some standards in terms of the data representation and communication. CIM and OPC-UA are the international standards widely used in smart grid domain for enabling interoperability. They provide common information model and the unified architecture for communicating between each systems or applications. In this paper, we illustrate a smart grid operating system that we have developed to secure interoperability between not only applications but also numerous legacy systems(applications) by implementing CIM based information model and OPC-UA based communication interface services.

Many countries are increasing their investments in smart grid technology to enhance energy efficiency, address climate change, and trigger a green energy revolution. In addition to these goals, Korea also seeks to promote national competitiveness, prepare for the growth of the renewable energy industry, and export industrialization through its strategic promotion of the smart grid. Given its inherent representativeness for Korean implementation of the smart grid and its growth potential, Jeju Island was selected by the Korean government as the site for smart grid testing in June 2009. This paper presents a new design for the electricity market and an operational scheme for testing Smart Electricity Services in the Jeju smart grid demonstration project. The Jeju smart grid test-bed electricity market is constructed on the basis of day-ahead and real-time markets to provide two-way electricity transaction environments. The experience of the test-bed market operation shows that the competitive electricity market can facilitate the smart grid deployment in Korea by allowing various demand side resources to be active market players.
