Power-Electronic-Dominated Microgrids for Electric Propulsion and Sustainable Energy Systems
“面向电力推进与可持续能源系统的电力电子主导型微电网”

The increasing penetration of renewable energy resources, energy storage systems, and electrified transportation is accelerating the development of power-electronic-dominated microgrids. In these systems, converters are no longer only energy conversion interfaces, but also key control elements that determine system stability, power quality, dynamic performance, and operational reliability. This Special Issue focuses on advanced power electronics, microgrid stability and control, and electric propulsion systems under a unified framework of converter-enabled microgrid technologies.
Modern microgrids, including shipboard microgrids, onshore-power systems, electric vehicle microgrids, more-electric aircraft power systems, and hybrid AC/DC distribution networks, rely heavily on coordinated converter and inverter control. The design of power converter topologies, modulation methods, grid-forming and grid-following control strategies, and protection mechanisms directly affects voltage and frequency regulation, transient response, fault ride-through capability, and resilience under disturbances. Therefore, innovative converter technologies are essential for maintaining stable and efficient operation in highly dynamic microgrid environments.
Electric propulsion systems embedded microgrid provide an important application scenario for such technologies. In electric ships, aircraft, rail transportation, electric vehicles, and other electrified mobility platforms, propulsion motor drives, energy storage interfaces, onboard generation units, and charging or onshore-power facilities are commonly integrated through microgrid architectures. These systems require high-performance power electronic interfaces, coordinated energy management, fault-tolerant control, and system-level optimization to satisfy demanding requirements on efficiency, stability and reliability.

可再生能源、储能系统和电气化交通的渗透率不断提升，正在加速推动以电力电子为主导的微电网发展。在这些系统中，变换器不再仅仅是能量转换接口，而是决定系统稳定性、电能质量、动态性能和运行可靠性的关键控制单元。本专刊以“变换器赋能的微电网技术”为统一框架，聚焦先进电力电子、微电网稳定与控制以及电力推进系统等研究方向。
现代微电网，包括船舶微电网、岸电系统、电动汽车电网、多电飞机电力系统以及交直流混合配电网络，均高度依赖变换器与逆变器的协调控制。功率变换器拓扑结构、调制方法、构网型与跟网型控制策略以及保护机制的设计，直接影响电压和频率调节、暂态响应、故障穿越能力以及扰动下的系统韧性。因此，创新型变换器技术对于维持高动态微电网环境下的稳定、高效运行至关重要。
嵌入微电网架构的电力推进系统为上述技术提供了重要的应用场景。在电动船舶、飞机、轨道交通、电动汽车以及其他电气化移动平台中，推进电机驱动系统、储能接口、车/船/机载发电单元以及充电或岸电设施通常通过微电网架构实现集成。这些系统需要高性能电力电子接口、能量管理协调系统、容错控制以及系统级优化，以满足效率、稳定性和可靠性方面的严格需求。
