可重构的复用电力电子设备（M-PEDs）能够为主动配电网中的应用提供更有效、更灵活的运行方式，从而缓解热约束和电压越限问题。迄今为止，这些M-PEDs的运行方法尚未被描述，而由于它们相对于传统PEDs的复杂性，这是一个重要问题。本文提出了一种基于状态机的控制理念，可用于管理M-PEDs的互斥选择器信号和电流控制信号。基于该理念描述了两种控制方法：一种适用于无时间关键网络约束系统的离线（Off-Load）方法；另一种是在必须最小化暂态影响时实施的热插拔（Hot-Swap）方法。仿真展示了背靠背电压源变换器拓扑中状态机的演变过程。结论表明，所提出的基于状态机的控制理念能够在管理这一有前景的变换器拓扑额外复杂性的同时，实现M-PEDs的运行。
英文摘要
Reconfigurable, multiplexed power electronic devices (M-PEDs) can provide more effective, flexible operation for applications in active distribution networks, enabling the mitigation of thermal constraints and voltage violations. To-date, operational approaches of these M-PEDs have not been described, a significant issue as a result of their relative complexity as compared to conventional PEDs. This work proposes a state machine-based control philosophy that can be used to manage the mutually exclusive selector- and current-control signals for M-PEDs. Two control approaches are described using this philosophy: an Off-Load approach, suitable for systems without time-critical network constraints; and a Hot-Swap approach, implemented when the impact of transients must be minimized. Simulations illustrate the evolution of the state machine for a back-to-back voltage source converter topology. It is concluded that the proposed state machine-based control philosophy enables M-PED operation whilst managing the additional complexity of this promising converter topology.
