如今，传统电力系统正在向现代智能电网发展，其中互连的微电网可能在配电系统中占据主导地位，可再生能源和储能系统的渗透率很高。具有直流和交流电源/负载的混合交直流系统被认为是未来最有可能的配电甚至输电结构。对于这种混合交流/直流微电网，电源管理策略是最关键的运行方面之一。本文概述了交直流混合微电网系统的功率管理策略，包括不同的系统结构（交流耦合、直流耦合和交直流耦合混合微电网）、不同的运行模式、对稳态和瞬态条件下各种功率管理和控制方案的深入研究，以及功率管理和控制策略的示例。最后，对进一步研究的电源管理策略进行了讨论和建议。
Today, conventional power systems are evolving to modern smart grids, where interconnected microgrids may dominate the distribution system with high penetration of renewable energy and energy storage systems. The hybrid ac/dc systems with dc and ac sources/loads are considered to be the most possible future distribution or even transmission structures. For such hybrid ac/dc microgrids, power management strategies are one of the most critical operation aspects. This paper presents an overview of power management strategies for a hybrid ac/dc microgrid system, which includes different system structures (ac-coupled, dc-coupled, and ac-dc-coupled hybrid microgrids), different operation modes, a thorough study of various power management and control schemes in both steady state and transient conditions, and examples of power management and control strategies. Finally, discussion and recommendations of power management strategies for the further research are presented.
