“…In order to enhance network performance and flexibility, the rapid development of flexible interconnection technology based on SOPs realized flexible interconnection between feeders. Ebrahimi H (2024a) proposed that SOPs can be installed in the end feeders of the distribution network to improve network performance. Harmonic distortion, voltage imbalance, and active power loss can be minimized through active and reactive power control and selective harmonic current injection.…”

The optimization dispatching problem of the regional distribution network (DN) interconnection with the microgrid (MG) is studied in this paper. By installing flexible interconnection devices based on the soft open point (SOP) at the boundaries of DNs, the flexible interconnection can be achieved between distribution networks, and the distribution zoning model is established. A multiobjective DN–MG system optimization dispatching model for multi-area DNs considering distributed resources is established based on the distribution zoning model. By introducing intermediate coupling variables, the optimization dispatching problem of the DN–MG system is decomposed into MG sub-area optimization problems and DN sub-area optimization problems. On the basis of the above, a method based on the alternating direction method of multipliers (ADMM) is proposed to solve the optimization dispatching model. Finally, simulation verification shows that by application of the proposed method, the economic efficiency of the DN–MG system is improved effectively.
