摘要
移动应急资源的优化调度已被证实是提升电网灾后恢复能力与韧性的"助推器".已有调度方法均将载体与其承载的功能模块"捆绑"为一体,低估了资源的实际效用.为此,该文提出移动应急资源的分体式调度方法,其特征在于将载体与功能模块"分解"为独立的调度单元,从而涌现出"一带多"与"载体共享"机制,以挖掘移动应急资源的利用潜力、探寻更优的调度效果.通过对载体、功能模块、电网三者间的交互行为进行分析,引入关键0-1变量,将实现分体式调度所需的各逻辑条件分别建立为线性约束条件;围绕电网灾后恢复场景,以最大化负荷供应为目标,并兼顾资源部署成本,建立计及移动储能、移动发电机、维修资源3类移动应急资源分体式调度的混合整数线性优化模型.最后,在IEEE配电系统上进行算例测试,结果表明,所提模型能够有效实现载体与功能模块间的灵活搭配与协同,并验证了分体式调度方法相对于传统方法的优势及其可扩展性.
Abstract
Optimal scheduling of mobile emergency resources has proved to be a booster of power system restoration ability and resilience.However,in existing studies,the carrier and the mounted functional module are"bundled"as one whole,leading to an underestimation of the performance of these resources.To bridge this gap,a component-separating scheduling method of mobile emergency resources is proposed,which is characterized by separating the carrier and the functional module into independent scheduled units.The mechanisms of"one carrying more"and"sharing carriers among resources"therefore spring up,making it possible to further tap the potential of mobile emergency resources and pursue better scheduling results.By analyzing the interactive behaviors among carriers,functional modules,and grids and introducing vital binary variables,the logical conditions to achieve component-separating scheduling are formulated as linear constraints.Then,for the post-disaster restoration case of power system,a mixed-integer linear programming model is built,involving the component-separating scheduling of mobile energy storage systems,mobile generators and repair resources,with the objective of maximizing energy supply to the demand while considering the cost of resources deployment.Numerical tests are finally conducted on IEEE test feeders and results show that the proposed model effectively realizes flexible collocation and cooperation among the carriers and functional modules.Besides,the advantage of component-separating scheduling method over other traditional ones and its scalability are verified.
