A Very Short-Term Load Forecasting Method for Economic Load Dispatching Control

Abstract

This paper proposes a very short-term load forecasting technique in order to make Economic Load Dispatching Control (EDC) more effective. The controllable periodic term of EDC is made clear through power spectrum analysis of actual load and actual EDC outputs of the Kansai Electric Power Company. A real-time predictor is designed based on this result, and it can decrease the EDC error at almost the same level as the actual AR (Area Requirement: final error after EDC and LFC) through the year. In addition, it can be seen from the generation simulation by using this predictor that we can decrease the fuel cost and LFC margin.
