This paper describes reasonable methods by considering change of outdoor temperature into Customer Baseline Load(CBL) of Demand Resources in Smart Demand Resource Market, which controls peak power demand and maintains reliability of power system. The Smart Demand Resouce Market, which KPX(Korea Power Exchange) implement, is explained and then effects for CBL calculated by considering temperature correction factor are established. Finally, four methods for calculation of CBL are proposed and those results are compared and analyzed.

수요반응(DR : Demand Response)은 스마트 그리드(Smart Grid)를 구성하는 핵심 요소 중 하나이다. 본 논문에서는 스마트 그리드 환경 하에서 ISO(Independent System Operator)의 수요자원시장에 참여함과 동시에 말단 수용가들을 대상으로 다수의 DR 프로그램을 운영하는 LA(Load Aggregator)사업자의 DR자원 운영 시스템에 대한 전반적인 개념 및 흐름에 대하여 기술하였다. 또한, 스마트 그리드 하에서 LA사업자의 DR자원 운영 시스템 설계 중 LA사업자의 DR자원 최적배분 전략에 대한 개념 및 예시를 제시하였다.

Electricity industries throughout the world are undergoing unprecedented changes. As a result, these changes lead to the separation of traditional integrated utilities and the introduction of competition in order that increase efficiency in electricity industry. Direct load control (DLC) system in competitive electricity market has a hierarchical interactive operation system, therefore, its control logic is also applied by bilateral interactive method that interchanges information related to interruptible load between operation hierarchies. Consequently, load curtailment allocation algorithm appropriate for new DLC system is required, and based on interchanged information, this algorithm should be implemented by most efficient way for each operation hierarchy. In this paper, we develop the load curtailment allocation algorithm in an emergency for new DLC system. Especially, the optimal algorithm for load aggregator (LA) that participates in competitive electricity market as a main operator for load management is developed.
