Multi-Objective Reconfiguration of Wind-Integrated Distribution Network Considering Network Resiliency

Network resiliency refers to the connectivity performance and ability to withstand damage. This paper introduces network vulnerability as a new objective to describe the network resiliency in distribution network reconfiguration (DNR), which effectively quantifies topological reliability. The method utilizes weighted edge values and modified node importance to calculate network vulnerability. Additionally, the approach accounts for the randomness and intermittency of distributed generation (DG) and adjusts the index values for the access position of DGs. A multi-objective model is established for DNR with DGs that considers network vulnerability. Through Pareto optimal concept and improved harmony search algorithm, a set of valuable and practical solutions is provided. The efficacy of the model and algorithm is demonstrated through case studies.
