摘要
针对社区型能源互联网中用户群体具有较高的社会聚集性特点,用户间社交关系对各自的负荷曲线、购能成本及交易决策等均有直接影响,文章提出了一种考虑社交网络关系的区域型综合能源交易模式。利用社交联盟内用户间转移可平移负荷消纳冗余的间歇式能源(光伏)出力特点,提出了含用户结盟的社区型能源互联网交易机制;构建了考虑社区综合能源运营商与多用户及联盟利益冲突的主从博弈模型,并采用分布式遗传算法对该模型进行求解。仿真结果表明:用户结盟不仅对提升间歇式能源出力消纳有积极作用,且能增加参与主体收益;用户结盟力度越强,运营商盈利空间越狭窄,但系统社会效益越大,特别在用户负荷峰值时段能显著降低电网侧电量,有利于缓解电力系统供能负担,为未来社区型能源互联网运营提供参考。
In view of the high social aggregation of users in the community-based energy internet,and the direct influence of users’social relations on their respective load curves,energy purchase cost and transaction decision,a mode of regional comprehensive energy transaction considering social network relations is proposed.Since load transfer among users in the social alliance is helpful to absorb the redundancy of intermittent energy(PV)output,a community-based energy internet trading mechanism with user alliance is proposed.A master-slave game model considering the conflict of interests between community comprehensive energy operators,multi-users and alliance is constructed and solved by distributed genetic algorithm.Simulation results show that user alliance not only has a positive effect on promoting intermittent energy consumption,but also can increase the income of participants.The stronger the user alliance is,the narrower the operator’s profits gains,however,the larger the social benefits of the system will be.Especially in the peak period of user load,it can significantly reduce the grid-side power load and alleviate the power supply burden of the power system.Thus,this mode can provide reference for future community-based energy internet operation.
