摘　　要：随着可再生能源渗透率的提高以及能源转型进程的推进,能源系统在保证调度策略鲁棒性的同时,也要考虑系统的绿色性和低碳性.针对含碳捕集机组的社区型能源系统中各社区在风电功率不确定性下的最优决策问题,提出一种非合作博弈模式下的分布鲁棒优化方法.首先,以运行成本最低为目标,构建各社区的两阶段调度模型.其次,将风电功率的分布信息纳入到两阶段模型中,考虑各社区之间的非合作博弈关系,构建分布鲁棒博弈模型.最后,利用线性决策理论及对偶原理求解模型.仿真结果表明,所提分布鲁棒博弈方法可以保证博弈策略的鲁棒性,同时也克服了鲁棒优化强保守性的问题.With the increasing penetration of renewable energy and the requirements of energy transition,green and low-carbon operation of energy system should be considered while ensuring the robustness of scheduling strategy.In this paper,a low-carbon robust scheduling method is proposed for community energy system which takes the uncertainty of wind power and the game relationship among multi-decision makers into consideration.Firstly,a two-stage scheduling model for each community is constructed.Secondly,the distribution information of wind power is incorporated into the two-stage model and the non-cooperative game relationship among communities is considered.Finally,the linear decision theory and duality principle are used to solve the model.Result shows that the proposed method can obtain the strategy with high robustness and overcome the strong conservatism of traditional robust optimization.
