Multi-objective Optimization Control Strategy for Soft Open Point in Distribution Network with High Penetration of DG

doi:10.11930/j.issn.1004-9649.202405027

Abstract

Abstract:

A multi-objective optimization control strategy for distribution station SOP is proposed to enhance the distributed generation (DG) consumption capability of the distribution network by utilizing multi soft open point (SOP). By analyzing the access mode of SOP in the distribution network and considering its role in distributed power consumption and peak shaving, a multi-objective model was constructed to maximize the daily consumption of distributed energy, minimize control costs, and minimize the deviation of daily net load of feeder lines. Conduct simulation comparison and verification using an improved distribution network example. The results indicate that SOP integration is beneficial for improving the consumption of new energy and achieving load balancing.

Key words: soft open point, distribution network, distributed estimation, multi-objective optimization
