基于两阶段算法的含SOP配电网多源协同随机恢复
Multi-source coordinated stochastic restoration for SOP in distribution networks with a two-stage algorithm
摘要
Abstract
After suffering from a grid blackout,distributed energy resources(DERs),such as local renewable energy and controllable distributed generators and energy storage can be used to restore loads enhancing the system's resilience.In this study,a multi-source coordinated load restoration strategy was investigated for a distribution network with soft open points(SOPs).Here,the flexible regulation ability of the SOPs is fully utilized to improve the load restoration level while mitigating voltage deviations.Owing to the uncertainty,a scenario-based stochastic optimization approach was employed,and the load restoration problem was formulated as a mixed-integer nonlinear programming model.A computationally efficient solution algorithm was developed for the model using convex relaxation and linearization methods.The algorithm is organized into a two-stage structure,in which the energy storage system is dispatched in the first stage by solving a relaxed convex problem.In the second stage,an integer programming problem is calculated to acquire the outputs of both SOPs and power resources.A numerical test was conducted on both IEEE 33-bus and IEEE 123-bus systems to validate the effectiveness of the proposed strategy.关键词
