摘要
针对电气化船舶充电可能引发配网潮流分布失衡的问题,设计了一种新型的港口配电网日前经济调度策略。首先,分析全电集装箱船(electric container ship,ECS)和冷藏集装箱(reefer container,RFC)的时空协同转移和弹性用电特性,提出2者能量时空协同响应配网功率调节需求的构想。在此基础上,充分考虑风力发电不确定性,计及ECS&RFC能量时空协同响应约束,以日运行成本最小化为目标,建立了港口配电网日前鲁棒经济调度模型,并采用Shapley值法"按劳分配"ECS和RFC需求侧响应收益。基于IEEE11节点配网和10条电动船舶的仿真结果表明,所提出的日前经济调度策略较于传统方案,港口配网年运行成本降低7.9%,具有可行性和合理性,同时基于Shapley值法的利益分配能够保证成员利益分配的公平、合理性。
Aiming at the problem that the charging for electrified ships may cause the imbalance of distribution network tidal current distribution,we designed a new type of port distribution network day-ahead economic dispatch strategy.First,we analyzed the temporal and spatial coordinated transfer and flexible power consumption characteristics of all-electric container ships(ECS)and refrigerated containers(RFC),and proposed a concept of coordinated response to the power regulation demand of the distribution network.On this basis,the uncertainty of wind power generation was fully taken into consideration,and the constraints of ECS&RFC energy spatio-temporal coordination response were taken into account,so that,a day-ahead robust economic dispatch model for the port distribution network was established with the goal of minimizing daily operating costs,and the Shapley value method"distribution according to work"ECS and RFC demand side response benefits were introduced.The simulation results based on the IEEE 11-node distribution network and 10 electric ships show that the day-ahead economic dispatch strategy proposed in this paper reduces the annual operating cost of the port distribution network by 7.9%compared with the traditional scheme,which is feasible and reasonable,and is based on the Shapley value method.The distribution of benefits can ensure the fairness and rationality of the distribution of benefits among members.
