研究了考虑多周期攻击的微电网防御资源规划与分配问题。基于多周期防御-攻击-防御模型，分别对防御输电线路和分布式发电机进行规划和分配，以减轻输电线路的多周期攻击损害，并使微电网的卸载负荷最小化。利用鲁棒优化技术对问题进行表述，形成两阶段决策过程：第一阶段，防御方提出防线规划和DG分配方案，以使攻击方损失最小；在第二阶段，攻击者以多周期攻击破坏微网系统的输电线路为目标，对微网系统造成最大的破坏，防御者则对剩余的微网系统进行潮流优化，使卸载负荷最小化。基于自定义的列约束生成算法开发了求解过程。数值实验验证了该模型和算法的有效性和优越性。此外，还对各种参数和设置进行了灵敏度分析。
This paper investigates a microgrid defense resource planning and allocation problem with the consideration of multi-period attacks. The defensive transmission lines and distributed generators (DGs) are, respectively, planned and allocated to mitigate the multi-period attack damage on transmission lines and minimize the shed loads for microgrid, based on a multi-period defender–attacker–defender model. Robust optimization technique is utilized for the problem formulation, resulting in a two-stage decision process: in the first stage, the defender proposes defensive line plan and DG allocation scheme for the purpose of minimizing the attacker’s damage; and in the second stage, the attacker disrupts the transmission lines of microgrid system aiming at the maximum damage by the multi-period attacks, then the defender reacts to optimize the power flow on the remaining microgrid system to minimize the shed loads. Solution process is developed based on the customized column-and-constraint generation algorithm. The effectiveness and superiority of the proposed model and algorithm are validated with numerical experiments. In addition, sensitivity analysis is also carried out with various parameters and settings.
