In a hydrogen-based DC microgrid (MG), the integration of hydrogen subsystem increases the system complexity and flexibility. Effective power split, bus voltage stability and reliable operation become significant control issues of hydrogen-based DC MG. This paper proposes a simple and effective decentralized energy management strategy based on a mode-triggered droop scheme for an islanded PV/hydrogen/battery DC MG. In a decentralized manner, the proposed decentralized energy management strategy is implemented through two control steps: mode divisions and droop control. For practical implementation purposes of the proposed energy management strategy, the mode divisions scheme autonomously divides this DC MG into eight operating modes based on the system local information; the adaptive droop control method controls the distributed generation units based on their droop relationships under different operating modes. In addition, an islanded DC MG hardware-in-the-loop (HIL) RT-LAB simulation platform and a lab-scaled experimental platform are built to validate the effectiveness of the proposed decentralized strategy. The simulation and experiment results show that the proposed energy management strategy has an efficient power distribution ability without communication link under various operating modes.

用于孤岛混合光伏/氢/电池直流微电网分散能源管理的模式触发下垂方法

在氢基直流微电网(MG)中,氢子系统的集成增加了系统的复杂性和灵活性。有效的功率分配、母线电压稳定和可靠运行成为氢基直流MG的重要控制问题。本文提出了一种基于模式触发下垂方案的简单有效的分散式能源管理策略,用于孤岛光伏/氢/电池 DC MG。以分散的方式,提议的分散能源管理策略通过两个控制步骤实施:模式划分和下垂控制。为了所提出的能源管理策略的实际实施目的,模式划分方案根据系统本地信息自动将这个 DC MG 划分为八种工作模式;自适应下垂控制方法根据分布式发电机组在不同运行模式下的下垂关系进行控制。此外,还建立了孤岛 DC MG 硬件在环 (HIL) RT-LAB 仿真平台和实验室规模的实验平台,以验证所提出的分散策略的有效性。仿真和实验结果表明,所提出的能源管理策略在各种运行模式下都具有无需通信链路的高效配电能力。
