📝 摘要(中文)

随着发电机在大规模电力系统中的分布,缺乏对发电机距离信息的考虑使得多发电机系统的协同操作面临挑战。本文提出了一种针对异构电池储能系统(BESS)的分布式逐步有限时间共识方案,能够在有限时间内实现协调共识,具有重要的电气工程应用价值。具体而言,所有BESS根据位置被划分为多个集群,每个集群有一个主动领导者负责外部信息接收。为协调多BESS,采用五个功能导向的输入实现能量水平平衡、功率共享及电压/频率同步。此外,通过引入虚拟领导者,实现了频率和电压恢复至主网的标称值。与集中式方法相比,该控制方案完全分布式,且对负载扰动和通信拓扑的插拔具有鲁棒性。最后,在修改后的IEEE 57节点系统上进行了仿真实验以验证所提方案。

🔬 方法详解

问题定义:本文旨在解决异构电池储能系统(BESS)在多发电机协同操作中因缺乏距离信息而导致的效率低下问题。现有集中式方法在信息传递和协调方面存在局限性,难以适应动态变化的电力系统环境。

核心思路:论文提出的分布式逐步有限时间共识方案,通过将BESS划分为多个集群并设定主动领导者,利用局部信息实现全局协调,确保在有限时间内达到共识状态。

技术框架:整体架构包括集群划分、信息接收与处理、功率共享与电压频率同步等模块。每个集群内的领导者负责信息的接收与协调,虚拟领导者则用于频率和电压的恢复。

关键创新:该方案的主要创新在于其完全分布式的控制策略,避免了集中式方法的局限性,使得每个BESS仅依赖自身及邻居的信息进行决策,增强了系统的鲁棒性。

关键设计:在设计中,采用了五个功能导向的输入来实现能量平衡和功率共享,确保系统在负载扰动和通信拓扑变化下的稳定性。

📄 摘要(原文)

As all generators are distributed in different areas among large scale power systems, the cooperative manipulation of the multi-generator system cannot be done well without consideration of the distance information of the generators, A distributed step-by-step finite-time consensus scheme for the heterogeneous Battery Energy Storage System (BESS) is proposed in this paper, where the coordinated consensus can be come into reality within a limited time, which is appealing for the electrical engineering community. To be concrete, at first, all BESSs are classified into several clusters according to their locations, and in each cluster, there is an active leader in charge of information receiving from outside. Then after, in order to coordinate the multi BESSs, five inputs, which are function oriented, were used to achieve energy level balancing, active/reactive power sharing, and voltage/frequency synchronization of the multi BESSs. To be further, the frequency and voltage restoration to the nominal values of the main grid was made possible by the introduction of a virtual leader, which is actually an external leader. Compared with the centralized methods, this control scheme is entirely distributed, and each BESS only utilizes the information of its own and its neighbors. Besides, this control is robust to the load perturbation and the plug-and-play of the communication topology. Finally, some simulation experiments are executed on the modified IEEE 57-bus system to verify the suggested scheme.
