Abstract:With the development and further maturity of power electronic equipment technology, the load characteristics on the end-user side show some new characteristics: (1) stronger randomness and uncertainty; (2) more significant short-term peak power; (3) more difficult to evenly distribute the three-phase load power. To help distribution network operators dispatch process and better serve end users, this article will use the real data information of smart meters in a 10kV distribution station area in Qingzhen for the whole year of 2023 to analyze. By analyzing the load power time series characteristics in different smart meters representing different types of terminal users, we established three different indicators to describe the load power and its phase power imbalance time series characteristics: ① load power curve fluctuation coefficient index; ② peak power duration proportion index; ③ load three-phase power imbalance index, etc., based on these three indicators, this paper will provide scientific guidance for the operation of distribution network and the design of power electricity market mechanism for end users.
