摘要:

分布式能源在建筑领域的渗透率不断提高,加上交通行业电气化政策的不断完善,对电网的成本效益和可靠运行提出了挑战。本研究利用基于混合博弈论的点对点(P2P)电力交易范式和传统的使用时间,对由考虑电动汽车(EV)的异构建筑社区组成的多微电网之间的电力交易进行比较研究 Peer-to-grid(P2G)范式下的分时电价(TOU)策略。首先,基于混合博弈的P2P框架,结合非合作博弈来确定代表不同建筑社区的多个微电网之间的内部电力交易和价格,并提出了合作博弈来确定同一微电网建筑物内的交易和收入分配。然后,该研究探讨了这种方法在微电网内实现高效和可持续电力交换的有效性。通过综合分析,考虑动态电力需求和技术经济因素,结果表明基于混合博弈论的P2P范式相较于在P2G范式下TOU策略具有显着优势。所提出的方法可以改善能源供需平衡,增加能源自主权,公平的收入分配,并减少对公用电网的依赖。同时,利用电动汽车和灵活负载作为能源灵活性资源,进一步增强系统的灵活性和对需求波动的响应能力。研究结果为通过促进能源共享和增强电网稳定性来提高能源效率和支持向更加分散和有弹性的电力系统过渡提供了参考。

Abstract:

The ever-growing penetration rate of distributed energy resources in the building sector, coupled with the ongoing improvements in electrification policies within the transportation industry, has posed challenges to cost-effectiveness and reliable operation of the utility grid. This study conducts a comparative study on electricity transactions between multi-microgrids comprising heterogeneous building communities considering electric vehicles (EVs), utilizing a hybrid game theory-based Peer-to-peer (P2P) electricity trading paradigm and a traditional Time-of-use (TOU) strategy under the Peer-to-grid (P2G) paradigm. Firstly, a hybrid game-based P2P framework, incorporating a non-cooperative game for determining internal electricity transactions and prices between multi-microgrid representing different building communities, and proposed a cooperative game for determining transactions and revenue distribution within the same microgrid's buildings. Then, the study investigates the effectiveness of this approach in enabling efficient and sustainable electricity exchange within microgrids. Through a comprehensive analysis, considering the dynamic electricity demand and techno-economic factors, the results demonstrates that the hybrid game theory-based P2P paradigm offers significant advantages over the traditional TOU strategy under the P2G paradigm. The proposed approach enables improved energy supply-demand balancing, increased energy autonomy, equitable revenue distribution, and reduced reliance on the utility grid. Meanwhile, utilizing EVs and flexible loads as energy flexibility assets further enhances the system's flexibility and responsiveness to demand fluctuations. The findings provide references for promoting energy efficiency and supporting the transition towards a more decentralized and resilient power system by fostering energy sharing and enhancing grid stability.
