区别于传统电池储能系统,动态可重构电池储能系统中众多状态各异的电池模组利用电力电子开关组合在一起,通过开关控制各模组接入方式,实现灵活的电池系统内部拓扑动态重构,调整各模组运行状态,保障电池系统的安全、高效运行。不同拓扑重构方式下的电池系统能够与外界交互的电气量(包括电压、电流和功率)不同,进而对外界的支撑能力也呈现明显差异。为了充分发挥动态可重构电池储能系统灵活运行优势,同时最大程度支撑用能主体,文中提出一种动态可重构电池网络与储能变流器双向交互协同运行策略,将可重构电池网络与储能变流器运行需求分为6种典型工况,通过两者信息互联互通和状态柔性协同,实现每种工况下的最佳性能匹配。基于MATLAB/Simulink搭建了详细仿真模型,验证了所有工况下所提控制策略的有效性。
Different from traditional battery energy storage systems
the dynamic reconfigurable battery energy storage system (DRBESS) consists of numerous battery modules with varying states
which are connected via power electronic switches. By controlling the access mode of each module via switches
flexible dynamic reconfiguration of the internal topology is achieved
thereby adjusting the operating condition of each module and ensuring safe and efficient system operation. Under different reconfiguration topologies
the battery system exhibits different exchangeable electrical quantities (including voltage
current
and power)
leading to significant variations in its external support capability. To fully leverage the flexible operation advantages of the DRBESS while maximizing support to the energy-consuming entities
this paper proposes a bidirectional interactive coordinated operation strategy between the dynamic reconfigurable battery network (DRBN) and the power conversion system (PCS). The operational requirements of the reconfigurable battery network and the PCS are classified into six typical operating conditions. Through information interconnection and flexible state coordination between the two sides
optimal performance matching under each condition is achieved. A detailed simulation model is built based on MATLAB/Simulink
and effectiveness of the proposed control strategy under all operating conditions is verified.
