摘要
随着“双碳”目标的提出,微电网作为分布式电源利用的有效形式,受到能源管理应用领域的广泛关注。随着微电网数量增加,多微网端对端(peer to peer,P2P)能源交易有助于促进区域内能源的互联互济和清洁能源的就地消纳。在考虑微电网的碳排放特性和需求响应潜力的基础上,构建多微网P2P能源交易模型实现配电侧供需协同以及确定其最优交易策略。首先,提出了微电网运行优化模型,以运行费用最小化为目标鼓励微电网参与需求响应;其次,实现微电网内部购售电和储能充放电碳排放的量化,并计算微电网的碳排放成本;再次,基于广义纳什议价理论构建P2P能源交易模型并在模型中加入潮流约束,在保证电力系统安全稳定运行的基础上实现多微网的能源共享和收益分配。最后,基于IEEE-33节点系统进行算例分析。结果表明,考虑需求响应和碳排放费用的多微网P2P能源交易有助于促进微电网之间的能源共享和新能源消纳。
With the introduction of the“double carbon”target,microgrid is considered an effective form that integrates renewable power sources and improves energy utilization efficiency.In line with the increasing number of microgrids,peerto-peer(P2P)energy trading among multiple microgrids is regarded as an effective solution for energy sharing and integration of distribution generation.This study proposes a P2P energy trading model that accounts for demand response and carbon emission characteristics to achieve supply and demand coordination while determining the optimal operation strategy.First,the microgrid in the model solves an economic optimization problem by participating in the demand response.Second,by considering carbon emission factors,the model offers a great opportunity to reduce operation and carbon emission costs,accounting for energy transactions and energy storage scheduling.To incentivize energy sharing among multiple microgrids,a P2P energy-trading model based on generalized Nash bargaining was developed that enables energy sharing and revenue allocation.In addition,optimal power flow constraints were incorporated into the model to enhance the security of power system operations.Finally,a simulation of the IEEE-33 system demonstrates that P2P energy trading among multiple microgrids effectively reduces operating costs and promotes the integration of renewable energy sources.
