Abstract

Microgrids are an active research field due to their integration of renewable and non-renewable energy sources alongside energy storage systems to supply both DC and AC loads. While existing studies extensively explore hierarchical control structures, focusing on algorithm design and optimization, practical implementation remains challenging due to system complexity. This paper presents the development of a low-power microgrid hardware platform based on power converters and controllers, enabling experimental validation of the second and third levels of hierarchical control. The platform enables real-time energy management using FPPT algorithms while providing an intuitive graphical interface for data visualization and system monitoring. Experimental results confirm the system’s capability of dynamically managing energy flows, ensuring stable operation under varying load conditions. The system demonstrates reliable operation handling loads of up to 100 W, with scalability to 200 W, providing an effective tool for testing and research in microgrid control strategies.

用于可再生能源和离网微电网教学和研究的灵活硬件

微电网是一个活跃的研究领域，因为它将可再生能源和不可再生能源与储能系统结合起来，同时提供直流和交流负载。虽然现有的研究广泛地探讨了分层控制结构，重点是算法设计和优化，但由于系统的复杂性，实际实施仍然具有挑战性。本文介绍了基于功率变换器和控制器的低功耗微电网硬件平台的开发，实现了二级和三级分级控制的实验验证。该平台使用FPPT算法实现实时能源管理，同时为数据可视化和系统监控提供直观的图形界面。实验结果表明，该系统具有动态管理能量流的能力，能够在不同负荷条件下稳定运行。该系统运行可靠，负载可达100w，可扩展至200w，为微电网控制策略的测试和研究提供了有效的工具。

期刊介绍： HardwareX is an open access journal established to promote free and open source designing, building and customizing of scientific infrastructure (hardware). HardwareX aims to recognize researchers for the time and effort in developing scientific infrastructure while providing end-users with sufficient information to replicate and validate the advances presented. HardwareX is open to input from all scientific, technological and medical disciplines. Scientific infrastructure will be interpreted in the broadest sense. Including hardware modifications to existing infrastructure, sensors and tools that perform measurements and other functions outside of the traditional lab setting (such as wearables, air/water quality sensors, and low cost alternatives to existing tools), and the creation of wholly new tools for either standard or novel laboratory tasks. Authors are encouraged to submit hardware developments that address all aspects of science, not only the final measurement, for example, enhancements in sample preparation and handling, user safety, and quality control. The use of distributed digital manufacturing strategies (e.g. 3-D printing) is encouraged. All designs must be submitted under an open hardware license.
