本文提出了一种基于动态博弈理论的网源协调的台风防御策略,减少线路加固成本,提高防御效率.该策略将台风设定为的理性博弈者(攻击),造成对电电网的最大损失,与电网规划者(防御)、黑启动电源规划者(防御)一起,构成“防御—攻击—防御”动态博弈模型的三方,并以此模型确定输电线的最优加固策略,以及黑启动电源容量与位置.本文采用2017年过境广东部分沿海地区的台风天鸽作为时间里,构建动态博弈模型,并通过仿真确定最优的输电线路加固位置,以及黑启动电源位置、容量.仿真结果显示本文所提出的台风防御策略有效使得电网负荷损失最小,证明了该策略的正确性与有效性.本文所提之方法亦可应用于不确定的大规模自然灾害防御.“,”A power source-power grid coordinated typhoon defense strategy is proposed in this study to minimize the cost of power grid anti-typhoon reinforcement measures and improve defense efficiency.It is based on multiagent dynamic game theory.This strategy regards a typhoon as a rational gamer that always causes the greatest damage.Together with the grid planner and black start unit(BSU)planner,it forms a multiagent defense-attack-defense dynamic game model naturally.The model is adopted to determine the optimal reinforcements for the transmission lines,black start power capacity,and location.Typhoon Hato,which struck a partial coastal area in Guangdong province in China in 2017,was adopted to formulate a step-by-step model of a typhoon attacking coastal area power systems.The results were substituted into the multiagent defense-attack-defense dynamic game model to obtain the optimal transmission line reinforcement positions,as well as optimal BSU capacity and geographic positions.An effective typhoon defense strategy and minimum load shedding were achieved,demonstrating the feasibility and correctness of the proposed strategy.The related theories and methods of this study have positive significance for the prevention of uncertain large-scale natural disasters.
