Abstract

This study introduces a hierarchical interaction model between a shared energy storage system (ESS) operator and self-interested ESS users, referred to as the shared ESS energy trading game (EET game). In the EET game, the ESS operator sets time-varying energy selling and buying prices to regulate energy trading among ESS users. Meanwhile, the ESS users make decisions regarding their energy selling (charging energy to the shared ESS) and buying (discharging energy from the shared ESS) schedules. We model the EET game as a generalized Stackelberg game (GSG) and define a generalized Stackelberg equilibrium (GSE) to identify the optimal strategies for both the ESS operator and ESS users. Within the EET game, we prove the existence of a variational Stackelberg equilibrium (VSE), which is a GSE. To compute this equilibrium, we utilize a gradient-based algorithm that incorporates an implicit gradient. Finally, we validate our model by simulation studies using residential households’ energy demand data and show the effectiveness of our approach in reducing both total energy cost (EC) and the peak-to-average ratio (PAR).

共享ESS能源交易博弈的激励设计

本文引入了共享储能系统（ESS）运营商与自利用户之间的分层交互模型，称为共享储能系统能源交易博弈（EET博弈）。在EET博弈中，ESS运营商设定随时间变化的能源买卖价格，以规范ESS用户之间的能源交易。同时，ESS用户对他们的能源销售（向共享ESS充电）和购买（从共享ESS放电）计划做出决策。我们将EET博弈建模为广义Stackelberg博弈（GSG），并定义了广义Stackelberg均衡（GSE）来确定ESS运营商和ESS用户的最优策略。在EET对策中，我们证明了变分Stackelberg均衡（VSE）的存在性，即GSE。为了计算这种平衡，我们使用基于梯度的算法，该算法包含隐式梯度。最后，我们通过使用居民家庭能源需求数据的模拟研究验证了我们的模型，并展示了我们的方法在降低总能源成本（EC）和峰均比（PAR）方面的有效性。

期刊介绍： The IEEE Transactions on Control Systems Technology publishes high quality technical papers on technological advances in control engineering. The word technology is from the Greek technologia. The modern meaning is a scientific method to achieve a practical purpose. Control Systems Technology includes all aspects of control engineering needed to implement practical control systems, from analysis and design, through simulation and hardware. A primary purpose of the IEEE Transactions on Control Systems Technology is to have an archival publication which will bridge the gap between theory and practice. Papers are published in the IEEE Transactions on Control System Technology which disclose significant new knowledge, exploratory developments, or practical applications in all aspects of technology needed to implement control systems, from analysis and design through simulation, and hardware.
