摘要

高效利用多样化资源参与灾后供电并实现配电网负荷的快速恢复，是提升配电网弹性的重要问题。为此，提出了一种考虑分布式储能聚合与应急资源协同的负荷恢复协同方法。首先，分别构建了分布式储能的聚合模型与应急资源的时空调度模型。其次，以最大化负荷恢复量为目标，协调电力维修队和线路开关实现网络重构，同时利用移动储能和分布式储能联合为孤岛负荷供电，构建配电网灾后协同恢复优化模型。然后，采用McCormick包络法对模型中的非线性项进行线性化处理，进而将所提模型转化为混合整数线性规划模型。最后，通过修改的IEEE33节点和IEEE118节点配电网验证了所提方法在提升负荷恢复水平和求解效率上的有效性。

Abstract

Efficient utilization of diverse resources for post-disaster power supply and rapid load restoration is crucial for improving distribution network resilience. To this end

a load restoration method considering distributed energy storage aggregation and emergency resource coordination is proposed. First

an aggregation model for distributed energy storage systems and a spatiotemporal scheduling model for emergency resources including mobile energy storage (MES) and maintenance crews are developed. Second

with the objectives of maximizing restored load quantity and minimizing total restoration cost

power maintenance teams and line switches are coordinated to realize network reconfiguration

while MES and distributed energy storage jointly supply power to isolated loads

forming a post-disaster coordinated load restoration optimization model for distribution networks. Subsequently

the McCormick envelope method is adopted to linearize nonlinear terms in the model

converting the original model into a mixed-integer linear programming model. Finally

case studies on modified IEEE33-bus and IEEE118-bus distribution networks verify the effectiveness of the proposed method in improving restored load volume and reducing computational time.
