This article presents an efficient design architecture of an islanded and scalable DC microgrid comprising several power management units (PMUs) and a time slot‐based control interface. There are two primary sections in this manuscript—performance analysis of a microgrid design with phase shift modulation (PSM)‐controlled dual active bridge (DAB) converter‐based PMUs to charge Li‐ion battery energy systems and design of a time slot‐based control scheme to regulate the operation of PMUs for future applications. The batteries can act as the power sources in home energy management systems, transactive energy systems and so on. The PMUs are connected in parallel to a capacitive bus, which is supplied power by a photovoltaic (PV) energy source. There is a maximum power point tracking (MPPT) control block, which is constituted by a perturb and observe (P & O) algorithm and boost converter average model. For performance evaluations, the DAB‐based microgrid design is developed and tested in MATLAB/Simulink [textregistered]. In the second section, the control interface design is illustrated and explained with the constituent algorithms. © 2020 Institute of Electrical Engineers of Japan.

具有双有源桥式转换器的电源管理单元和基于时隙的控制接口的孤岛式DC微电网架构

本文介绍了一个高效的岛式可扩展DC微电网的设计架构，该微电网包括多个电源管理单元（PMU）和基于时隙的控制接口。本手稿包含两个主要部分-使用基于相移调制（PSM）控制的双有源桥（DAB）转换器的PMU为锂离子电池能量系统充电的微电网设计的性能分析以及基于时隙的设计控制方案，以调节PMU的运行，以备将来使用。电池可以用作家庭能源管理系统，交互式能源系统等的电源。PMU并联连接至电容性总线，电容性总线由光伏（PV）能源供电。有一个最大功率点跟踪（MPPT）控制块，由扰动观察（P＆O）算法和升压转换器平均模型组成。为了评估性能，开发了基于DAB的微电网设计并在MATLAB / Simulink [textregistered]中进行了测试。在第二部分中，使用组成算法对控制界面设计进行了说明和解释。©2020日本电气工程师学会。由John Wiley＆Sons，Inc.发布
