FUTURE LOAD CURVE SHAPING BASED ON SIMILARITY USING FUZZY-LOGIC APPROACH

Load forecasting has always been essential to efficient power system p lanning and operation. In this paper, the authors propose the fuzzy lo gic approach for next-day load curve shaping based on similarity. The proposed approach has the advantage of dealing not only with the nonli near part of the forecast load curve but also with load forecasting ir respective of day type. In addition to these advantages, the proposed method is useful in situations where accurate forecasting models are d ifficult to design. The fuzzy logic approach is used to modify the loa d curves on similar days to shape the next-day load curve. The suitabi lity of the proposed approach is illustrated through an application to actual load data of the Okinawa Electric Power Company, Japan.
