摘要
针对能源互联配电网故障恢复的问题,采用主从博弈理论进行建模,所建立的能源互联配电网故障恢复模型计及了多个能源子网之间的多能互补协调。以发生故障后电能子网开关状态为主体博弈者的策略,以能源互联配电网故障恢复后系统的失电负荷量最小为主体博弈者的支付;以包括电能子网、热能子网、气能子网以及交通子网在内的各能源子网优化运行计划调整为从体博弈者的策略,以系统在故障期间综合运行成本最小为从体博弈者的支付,并计及各能源子网运行的必要约束。主体博弈者在提供故障发生后开关状态的同时从体博弈者对能源互联配电网的优化运行计划进行调整。仿真算例表明,能源互联配电网相比于传统配电网,系统在故障恢复之后的运行经济性以及可靠性均更高。
To solve the post-contingency recovery problem of distribution energy networks,a master-slave game theory-based approach is developed. The post-contingency recovery method of distribution energy networks considers multi-energy complementary and coordination. The strategy of the master problem is to adjust the post-contingency switch state of distribution network,which aims at minimizing the electricity shedding after the recovery of distribution energy networks. The operation strategies of subenergy networks including electricity,heat,natural gas,and transportation sub energy networks are adjusted in the slave problem. This problem minimizes the post-contingency total operation cost of multi-energy networks,and the necessary operational constraints of each sub energy network are considered. Hence,the master player adjusts the post-contingency switch state,while the slave player adjusts the operation strategy of distribution energy networks. Simulative results show that the distribution energy network provides more economic and reliable post-contingency operations in comparison with the traditional distribution network.
