Abstract

Abstract: In order to effectively evaluate the energy-saving potential of active distribution network, the evaluation method of energy-saving transformation scheme of distribution network is studied.The K-means clus-tering method is employed to extract typical scenarios of distribution network, and the forward push back method is used to calculate the power flow in typical scenarios, then energy-saving transformation schemes are for-mulated according to the power flow calculation results.A comprehensive energy-saving potential evaluation index system with multiple indexes is constructed, and a comprehensive evaluation method with hybrid decision-making model is proposed. The effectiveness of the proposed method is verified by a simulation example.

Key words: distributed generation, output power uncertainty, K-means clustering method, energy saving potential evaluation
