摘    要:船舶电力系统故障重构通过改变系统供电路径来恢复重要负载的供电,对增强系统的存活性有着重要意义。在多智能体(agent)架构的基础上,构建船舶电力系统博弈重构模型并提出求解方法。该模型以船舶电力系统中不同区域的agent作为博弈参与者,将船舶电力系统的重构问题转化为各agent之间的合作–竞争问题,从而保证重要负载的恢复供电。论文进一步提出该模型的求解算法,该算法首先判断博弈模式的合作与非合作属性,之后通过agent或agent联盟之间的博弈过程,计算各agent所属的负载/发电机的投切及转移策略。仿真算例表明,该算法能够快速有效地求解船舶电力系统重构问题,最大程度保证系统的存活性。

关 键 词:船舶电力系统  博弈论  合作/非合作博弈  多智能体系统  重构算法

Abstract:The reconfiguration process for shipboard power system(SPS) reroutes the electric power to restore the power supply for vital loads,and is central for the survivability of the system.Based on the multi-agent structure,this paper presented the game theory model of reconfiguration and its algorithm.The model,which considered the agents of different zones of SPS as the players of the game,transferred the reconfiguration problem of SPS into cooperation-competition problem of different agents in order to ensure the restoration of vital loads.This paper then gave the algorithm of the game model.The first step was to calculate the mode of the game which could be classified into the incooperative game or the cooperative game.The second step was to calculate the strategy of each agent for the load/generators’ switching and transferring by game process between agents or the coalitions of agents.Case studies show that this algorithm could solve the reconfiguration problem of SPS swiftly and effectively and the survival of the ship could be ensured as far as possible.
Keywords:shipboard power system  game theory  cooperative/incooperative game  multi-agent system(MAS)  reconfiguration algorithm
