A district and county-oriented distributed power supply carrying capacity rapid evaluation model construction method and device
By constructing an initial model structure based on dual definitions of administrative jurisdiction and electrical affiliation, the main grid and distribution network models are automatically generated, and time-series power flow calculations are performed for verification. This solves the problems of unclear assessment boundaries and inaccurate constraint transmission in the assessment of distributed power carrying capacity at the district and county levels, and achieves rapid and accurate assessment results.

Abstract
The application is suitable for the technical field of distributed power supply, and provides a district and county-oriented distributed power supply carrying capacity rapid evaluation model construction method and device, which comprises the following steps: constructing a model initial structure comprising a target area substructure and an equivalent area substructure, obtaining multi-source data of the target area substructure and the equivalent area substructure according to the definition result of the model initial structure, loading the multi-source data into the model initial structure, and generating a full-voltage level evaluation intermediate model comprising a main network model and a distribution network model; performing time sequence power flow calculation verification on the full-voltage level evaluation intermediate model, judging whether the power flow section of the full-voltage level evaluation intermediate model converges in all time periods, and determining the full-voltage level evaluation intermediate model after correction and full-time period convergence as a full-voltage level evaluation target structure as a district and county-oriented distributed power supply carrying capacity rapid evaluation model. The application effectively improves the modeling efficiency and the model reliability.
