Optimization Strategy for Black-Start Partitioning of Active Distribution Network to Minimize Customer Outage Cost

doi:10.11930/j.issn.1004-9649.202001032

Abstract

Abstract: When power system blackout occurs, the active distribution network with high penetration of distributed generations can realize fast parallel restoration through zone partitioning. An optimization strategy for black-start partitioning of active distribution network is proposed. With the minimum customer outage cost as objective, a mixed integer linear programming model is established for black-start partitioning of active distribution network, and the restoration operation sequences inside each partition are integrated into the partition model through the restoration constraints of distributed generations, lines, buses and loads. The linear programming solver ILOG CPLEX is adopted to solve the model, and then the partition restoration scheme of distribution network is obtained. The effectiveness of the proposed model and strategy is verified by the modified IEEE 69-bus distribution system.

Key words: black-start, partitioning, parallel restoration, active distribution network, mixed integer linear programming, customer outage cost
