本文提出了一种基于脉冲负荷集成的太阳能储能交直流混合微电网潮流控制新方法。该微电网以孤岛模式运行，同步发电机和光伏电站分别向系统的交流和直流侧供电。双向交直流逆变器通过控制交流侧和直流侧之间的有功和无功潮流，将交流侧和直流侧连接起来。光伏电站通过具有最大功率点跟踪（MPPT）功能的DC-DC升压转换器连接到直流总线。蓄电池组通过双向DC-DC转换器连接到直流母线。系统用连接到交流侧的脉冲负载进行测试。仿真结果验证了所提出的拓扑结构在孤岛模式下具有高效率、可靠性和鲁棒性，能够在临界负载下协调交流和直流侧的电源管理。
In this paper, a novel power flow control method for a hybrid AC-DC microgrid with solar energy, and energy storage is proposed for the integration of a pulse load. This micro grid works in islanding mode with a synchronous generator and PV farm supplying power to the system's AC and DC sides, respectively. A bidirectional AC-DC inverter is used to link the AC and DC sides by controlling the active and reactive power flow between them. The PV farm is connected to the DC bus through a DC-DC boost converter with maximum power point tracking (MPPT) functionality. A Battery bank is connected to the DC bus through a bidirectional DC-DC converter. The system is tested with a pulse load connected to the AC side. Simulation results verify that the proposed topology is coordinated for power management in both the AC and DC sides under critical loads with high efficiency, reliability and robustness in islanding modes.
