As most distributed energy resources (DERs) are accessible in urban areas, interest has increased in regards to evaluating the potential advantages from introducing virtual power plants (VPPs) comprised of DERs into such areas. A VPP provides a solution for improving an energy self-sufficiency rate, as an alternative to expanding the capacity of a conventional power plant (CPP). This research proposed a comprehensive method for analyzing the feasibility of using a VPP to benefit both the plant and demand sides. First, the energy-saving potential of a VPP composed of a photovoltaic (PV) and energy storage system (ESS) was explored, based on historical monitoring data in a Japanese smart community called Higashida District (with a size of approximately 1.2 km2). Second, the economic performance of the VPP was evaluated based on a payback period and total life cycle cost analysis. Then, considering the imbalance of the benefits between the demand and plant sides, cooperative game theory was applied to explore the cooperation potential. The influence of government subsidy policies on both the plant and demand sides was a simultaneous concern. Finally, the profit of the alliance, comprising both the demand and plant sides was allocated, based on the Shapley value. This study highlights the excellent energy-saving potential from implementing a VPP. The results show that there is substantial economic cooperation potential between the demand and plant sides. In addition, both the plant and demand sides have better profits in cooperative games than with non-cooperation. This research provides policy guidance for the Japanese government to promote VPPs in the future, and provides a solution for coordinating the profit allocations of the plant and demand sides.

基于合作博弈的虚拟电厂需求侧与经济侧之间的经济效益评价

由于大多数分布式能源(DER)都可以在城市地区获得,因此人们越来越有兴趣评估将由DER组成的虚拟电厂(VPP)引入此类地区的潜在优势。VPP提供了一种提高能源自给率的解决方案,作为扩展常规电厂(CPP)容量的替代方案。这项研究提出了一种综合方法,用于分析使用VPP既有利于工厂又有利于需求方的可行性。首先,根据日本智能社区东田区(面积约1.2 km 2)的历史监测数据,探索了由光伏(PV)和储能系统(ESS)组成的VPP的节能潜力。)。其次,基于投资回收期和总生命周期成本分析来评估VPP的经济绩效。然后,考虑到需求与工厂双方利益之间的不平衡,运用合作博弈理论探索了合作潜力。同时考虑到政府补贴政策对工厂和需求方的影响。最后,基于Shapley值分配了包括需求方和工厂方的联盟利润。这项研究强调了实施VPP所具有的巨大节能潜力。结果表明,需求方和工厂方之间存在巨大的经济合作潜力。另外,在合作游戏中,工厂方和需求方都比不合作方具有更好的利润。
