Optimal Dispatch of AC/DC Hybrid Low-voltage Distribution Network Based on Multi-mode Flexible Interconnection
The transformation for the distribution network by the flexible interconnection device can realize the flexible and efficient interaction between source
grid
load and storage
and solve the problems of load imbalance and power quality caused by the large number of distributed generators. Aiming at the flexible interconnection in low-voltage transformer area
an optimal dispatch model of AC/DC hybrid low-voltage distribution network based on multi-mode flexible interconnection is proposed. First
considering the networking forms of back-to-back and hybrid AC/DC low-voltage flexible interconnection devices
the low-voltage model of the flexible interconnection device and the PV-storage-charge-load element is established. Then
based on the low-voltage model
taking multi-level load imbalance degree
network loss and operation cost as optimization objectives
an optimal dispatch model of AC/DC hybrid low-voltage distribution network based on multi-mode flexible interconnection is proposed. Convex optimization theory is also used to convexize and linearize the model
and Gurobi solver is called to obtain the global optimal solution of the model. Finally
the effectiveness of the proposed model and the solution algorithm is verified by the case of AC/DC hybrid low-voltage distribution network.
