Service restoration method considering multi-regional mutual assistance of mobile electricity and hydrogen resources

电-氢-交通协同可以提高灵活性并增强能源系统韧性。提出了一种考虑移动电氢资源多区互济的负荷恢复方法。针对分布在多个区域的电-氢耦合系统,提出在停电期间协同利用本地的分布式电源、储氢和移动电氢资源,快速恢复关键用户需求。通过基于交通地图系统的移动电氢资源调度,提出了负荷恢复和移动电氢资源调度集成的故障恢复决策框架。进而构建了移动电氢资源交通调度与负荷恢复的耦合约束,建立了移动电氢资源参与恢复的混合整数二阶锥规划模型,可以进行恢复与交通调度的统一决策。所提方法从时间和空间维度协调和分配电氢资源,最大限度地恢复关键用户的需求。通过构建的多区域电-氢耦合系统和相对应的交通系统,验证了所提协同恢复方法的有效性和优越性。

Electricity-hydrogen-transportation coordination can increase flexibility and enhance energy system resilience.A service restoration method considering multi-regional mutual assistance of mobile electricity and hydrogen resources is proposed.For the interdependent electricity and hydrogen system distributed in multiple areas,it is proposed to collaboratively utilize local distributed power,hydrogen storage,and mobile electricity and hydrogen resources during outage to quickly restore critical user demands.Through mobile electricity and hydrogen resource dispatching based on the transportation map system,a restoration decision-making framework integrating load restoration and mobile electricity and hydrogen resource dispatching is proposed.Then the coupling constraints of mobile electricity and hydrogen resource transportation dispatching and load restoration are constructed,and a mixed integer second-order cone programming model for mobile elec⁃tricity and hydrogen resources to participate in restoration is established,which can make unified decisions on restoration and transportation dispatching.The proposed method coordinates and allocates electricity and hydrogen resources from time and space dimensions to maximize the demand restoration of critical user.The effectiveness and superiority of the proposed collaborative recovery method is verified by the constructed multi-regional electricity-hydrogen coupling system and the corresponding transportation system.
