Time Series Regulation Model of Aggregate Load of Distribution Network Based on Characteristic Analysis

Considering the influence of factors like new energy access, flexible load regulation, virtual electrical field, and demand response on the operation of the distribution network, the ‘bottom-up’ modeling method is adopted to propose a quasi-steady-state mechanism model including flexible load, virtual electrical field, and demand response resource. Based on the mechanism model, we proposed the response timing characteristics, load characteristics, and complementary characteristics of different resources. Taking into account the uncertainty of distributed new energy output, we proposed a time sequence adjustment model by Monte Carlo, scene reduction, and other methods for the aggregated load of the distribution network, according to the analysis of the characteristics of the flexible load, virtual electrical field, demand response, and other resources.
