Design of a Short-Term Load Forecasting System for Small Hydropower in the Context of Electricity Market

Abstract

On the basis of the analysis of influencing factors on small hydropower generation load, considering the characteristics of small hydropower load, this paper presents a short-term load forecasting system for small hydropower in the context of electricity market. It is composed of the following components: information collection and processing, load forecasting, information monitoring. The system uses a method to segment and cluster the load curves, then wavelet decomposition is applied to load data, and a complex forecasting model is taken. Meanwhile, fulfill feedback control through the part of information monitoring, and extended short-term load forecasting is introduced. The system can improve the overall level of short-term load forecasting for small hydropower.
