【摘要】 中国南方台风多发地区的电网防风加固等防灾资源分配与建设是大电网安全防御的关键问题之一,通常将其建模成防御者-攻击者-防御者(D-A-D)的动态博弈模型进行求解,但是现有的D-A-D模型没有考虑攻击者攻击顺序以及运行方式调整的动态过程。提出考虑攻击者攻击顺序以及潮流调整动态过程的多阶段动态博弈模型,并将其转化成可用列与约束生成算法(C&CG算法)求解的改进D-A-D模型,得出最优防御资源分配结果。在IEEE39节点系统上进行了所提的模型与算法的仿真,仿真结果表明,所提出的模型更加符合电网的实际情况,求解算法也更高效。更多还原

【Abstract】 In the typhoon-prone areas in southern China, the allocation of disaster prevention resources such as windproof reinforcement of power grid, is one of the key issues in the security defense of large power grid. The dynamic game model of defender-attacker-defender(D-A-D) is usually established to solve the problem. However, the existing D-A-D model does not consider the dynamic process of attacker’s attack order and operation mode adjustment. A multi-stage dynamic game model is thus proposed with consideration of the dynamic process of attacker’s attack order and dynamic process of power flow adjustment, and is transformed into an improved D-A-D model that can be solved by the column and constraint generation algorithm to obtain the optimal allocation of defense resources. The simulation results of the proposed model and algorithm on the IEEE39 node system show that the proposed model is more in line with the actual situation of power grid and the algorithm is more efficient.更多还原
