10 KV STATIC LOAD MODEL PARAMETER IDENTIFICATION METHOD BASED ON SIMILAR DAILY LOAD CURVES

摘要

A 10 kV static load model parameter identification method based on similar daily load curves. The method comprises: on the basis of a large number of daily load response characteristic curves, according to a static load model structure and a constraint condition, and according to two basic assumptions about a load theory, proposing a static load model parameter full-period optimization identification model; by means of optimization solving, giving 10 kV load full-period static voltage model parameters, obtaining change rules of load active and reactive power at each time point with changes in voltage, and obtaining change rules of load components. The method has good applicability, is suitable for static model analysis of large-scale 10 kV loads, and meets actual requirements.
