摘要

随着分布式光伏和共享储能系统在用户侧的扩展,开发跨区域的能源共享机制对于充分利用当地可再生能源资源和最大化系统的整体经济效益至关重要。建立了考虑共享储能的多区域能源运营商(MREO)模型,建立了基于主从博弈的两层交易优化框架。最初,设计了一个交易系统来评估电网、MREO和最终用户的利益。其次,建立了一个优化模型,以捕捉MREO决策与用户响应之间的动态交互。顶层模型由MREO管理,重点关注区域间的能源共享,根据区域需求制定灵活的电价,优化共享储能的使用。同时,底层模型解决了用户需求响应问题,允许用户根据MREO提供的信息修改其能源消耗并选择更有利的交易区域。仿真结果表明,所提模型准确地评估了各方的收益,迭代平衡了各方的利益,提高了用户和MREO的经济回报。此外,拟议的方法支持更大的当地光伏能源消耗,减少电网负荷波动,并促进所有利益相关者的互利结果。

Multi-regional energy sharing approach for shared energy storage and local renewable energy resources considering efficiency optimization
As distributed photovoltaic and shared energy storage systems expanded on the user side, developing an energy-sharing mechanism across different regions became crucial for fully utilizing local renewable energy resources and maximizing the system’s overall economic performance. This paper established a multi-regional energy operator (MREO) model considering shared energy storage, and a two-layer trading and optimization framework based on a master–slave game was developed. Initially, a trading system was devised to evaluate the interests of the power grid, MREO, and end-users. Next, an optimization model was formulated to capture the dynamic interactions between MREO decisions and user responses. The top-layer model was managed by MREO and focused on energy sharing among regions, which is used to set flexible electricity prices according to regional demand and optimize the use of shared energy storage. Meanwhile, the bottom-layer model addressed user demand response, allowing users to modify their energy consumption and select more advantageous trading areas based on information provided by the MREO. Simulation results confirmed that the proposed model accurately evaluated each party’s income, iteratively balanced their interests, and increased economic returns for both users and MREO. Additionally, the proposed approach supported greater local photovoltaic energy consumption, reduced grid load fluctuations, and fostered mutually beneficial outcomes for all stakeholders.
