A Study on Development of Reliability based Demand Response Program for Jeju Power Systems

As the penetration rate of PV and wind power generation increases, the reliability of the Jeju Island power system is threatened. If system operator can operate a reliability based Demand Response Program that can be operated separately from the main land system, it will help to secure the reliability of the Jeju Island power system. This paper presents the design method of the reliability based Demand Response Program which can be operated independently in the Jeju Island power system. As Jeju Island system has slight amount of industrial customer and large amount of tourism-related customer like accommodation facility while main land system has opposite configuration rate, demand curves of each system are different and must be treated seperatly. The proposed method includes a method of calculating the DR program operation time using the Jeju Island demand pattern analysis considering BTM distributed resources and the load forecasting model. The results of case studies prove the effectiveness of the proposed method. Estimated response time of each demand response which is result of simulation can decide register requirement of demand resource in Jeju Demand Response Program. © The Korean Institute of Electrical Engineers.
