Abstract

The deployment of distributed energy storage on the demand side has significantly enhanced the flexibility of power systems. However, effectively controlling these large-scale and geographically dispersed energy storage devices remains a major challenge in demand-side management. In this paper, we propose a CPS-based framework for controlling a distributed energy storage aggregator (DESA) in demand-side management. Within this framework, a distributed power tracking control algorithm is designed to ensure both power tracking and state-of-charge (SoC) balancing among the energy storage units (ESUs) within the DESA. The proposed algorithm utilizes a distributed observation-based approach that relies solely on local communication. It is demonstrated that the algorithm achieves power tracking convergence within a fixed time, while asymptotically achieving SoC balancing when assuming a connected communication network among the storage units. To validate the theoretical analysis and demonstrate the effectiveness of the proposed control strategy, an example scenario comprising six ESUs is presented.

需求侧管理中基于 CPS 的分布式储能聚合器功率跟踪控制
在需求侧部署分布式储能设备大大提高了电力系统的灵活性。然而,有效控制这些大规模、地理位置分散的储能设备仍然是需求侧管理的一大挑战。在本文中,我们提出了一个基于 CPS 的框架,用于在需求侧管理中控制分布式储能聚合器(DESA)。在此框架内,设计了一种分布式功率跟踪控制算法,以确保 DESA 内各储能单元 (ESU) 之间的功率跟踪和充电状态 (SoC) 平衡。所提出的算法采用基于观测的分布式方法,完全依赖于本地通信。实验证明,该算法可在固定时间内实现功率跟踪收敛,同时在假设储能单元之间存在连接通信网络的情况下,可渐进地实现 SoC 平衡。为了验证理论分析并证明所提控制策略的有效性,本文介绍了一个由六个 ESU 组成的示例场景。
