Based on the analysis and discussion about the findings, the authors summarized the library resource sharing system in satisfying users' information requirements, including its pros and cons. At last, further considerations have been provided on how to improve library resource sharing system in the region.展开更多
随着全国碳交易市场政策落地,为充分挖掘区域综合能源系统(regional integrated energy system,RIES)低碳减排能力,提高多区域综合能源系统接入主动配电网(active distribution network,ADN)的经济交互效益,提出了考虑灵活性资源与低碳...随着全国碳交易市场政策落地,为充分挖掘区域综合能源系统(regional integrated energy system,RIES)低碳减排能力,提高多区域综合能源系统接入主动配电网(active distribution network,ADN)的经济交互效益,提出了考虑灵活性资源与低碳交互结构的区域综合能源系统联盟参与配电网调峰调度的优化调度策略。建立了以主动配电网为主体,区域综合能源系统联盟为从体的主从博弈模型。主体以最大化交互效益目标制定分时电价策略,从体成员间通过联络线实现多能共享,考虑碳交易制度以供能与碳交易成本之和最小为目标,响应主体电价策略,建立了下层多区域综合能源系统联盟合作博弈优化模型。引入包含需求响应、储能和电动汽车在内的灵活性资源,配合碳捕集-电转气耦合机组优化联盟内部各系统的低碳供能策略,满足联盟负荷需求。基于纳什议价理论完成联盟成员合作收益的分配。通过算例验证所提策略能够有效减少各区域综合能源系统碳排放,并保障主从交互经济效益。展开更多
