Evaluation of the Refined Shiftable Potential of User Load

In-depth exploration of the shifting potential of shiftable load is the basis of applying shiftable load as a kind of demand-side resources to participate in power grid dispatching. In this paper, a refined evaluation model of load shifting potential including four characteristic indexes is proposed. Based on the historical electricity consumption data of the user, it is suitable for the situation that the user load is regarded as a shiftable whole participating in the grid dispatching when it is difficult to accurately control the user's equipment. Firstly, the K-Medoids clustering method with good noise robustness was used to cluster the historical load of users, and the typical daily load curve of users was obtained. Secondly, the characteristics of typical daily load curve of users were analyzed, and four indexes were proposed to measure load shifting potential, and a refined evaluation model for load shifting potential was established. Finally, through the analysis of a commercial load in reality, the validity and practicability of the proposed model are verified, which provides a reference for the shiftable load to participate in the grid dispatching.
