Problems solved by technology

However, under the existing conditions, due to the inconsistency between the network topology naming rules of the electricity consumption information collection system and the smart grid dispatching control system D5000, the data matching rate between the two is low, and it is difficult to use the bottom user power data to obtain the substation industry from top to bottom. constitute

Abstract

The invention discloses a method for obtaining the time-varying substation industry composition based on the daily load data of the bottom line of the EMS system and the daily load data of the special user, and adopts the method of longitudinal clustering and averaging to extract the typical daily load curve of each bottom line. ; Carry out horizontal clustering analysis on the typical daily load curves of all outgoing lines, and obtain the clustering situation of all bottom outgoing lines under the 220kV substation; finally, according to the industry affiliation of all bottom outgoing lines and special transformer users, aggregate from bottom to top to obtain the substation Industry composition ratio; the present invention analyzes based on EMS system data, can obtain substation industry composition ratio online, without manual statistical investigation; and can obtain time-varying industry composition ratio, which is beneficial to solve the time-varying problem of load modeling.

Description

technical field [0001] The invention belongs to the technical field of power system modeling, and in particular relates to a method for acquiring industry proportions of substations based on EMS data. Background technique [0002] The accuracy of the load model has an important impact on the power grid. An overly pessimistic load model will lead to excessive capital investment and serious waste; an overly optimistic load model will cause hidden dangers to the safe and stable operation of the power grid. There are two main methods to obtain the parameters of the load model. One is the overall measurement and identification method, which identifies the model parameters through the measured dynamic response, but this method is only effective for the fault moment, and the disturbance data is not easy to obtain; However, the actual load composition is complex, the statistical investigation is time-consuming and laborious, and this method is offline, so it is difficult to reflect ...
