Development of Local Renewable Management System in Regional KEPCO System

This paper introduces the Local Renewable Management System (LRMS), developed to evaluate static stability and optimize renewable energy source (RES) output within local power systems in Korea. While the central Energy Management System (EMS) manages RES connected at the transmission level, LRMS specifically targets high-voltage distribution networks. By leveraging weather forecasts, LRMS accurately predicts RES generation, assesses system stability through real-time monitoring, and applies necessary control actions, including preventive voltage adjustments and renewable curtailment. A detailed case study from the Jeju power system demonstrates LRMS’s efficacy in enhancing renewable integration while ensuring system stability.
