Load Prediction of Electric Heating Cluster and Its Influence on Rural Distribution Network

Abstract

With the gradual advancement of the "coal-to-electricity" project, a large number of electric heating equipment are connected to the rural power distribution network, and a new typical daily peak load in winter appears, which brings challenges to the safe and stable operation of the power distribution network. Therefore, this paper proposes a load forecasting method for rural distribution network connected to electric heating cluster and its impact on distribution network. First, a load forecasting model for rural heating with electricity is built; then, peak-valley correlation, network loss, and voltage offset are proposed to evaluate electricity the influence of heating cluster load on rural distribution network; finally, the effectiveness of the electric heating cluster load forecasting method proposed in this paper is verified by a typical example, and the impact of the electric heating access on the distribution network is evaluated by the proposed indicators.
