太阳能和风能等可再生能源为减少对传统发电的依赖并提高电力系统的可靠性和质量提供了有效的解决方案。本文介绍了一种实验室规模的太阳能微电网信息物理系统（CPS）的设计和实现，该系统以无线数据监测作为工程技术课程的教学工具。在该系统中，太阳能电池板、电池、充电控制器和负载构成物理层，而传感器、通信网络、监控和数据采集系统（SCADA）以及控制系统构成网络层。物理层与由控制和通信组成的网络层无缝集成。目标是创建一个强大的 CPS 平台，并利用该系统提高大学生对可再生能源的兴趣和知识。实验结果表明，最大功率点跟踪（MPPT）充电控制器为负载提供来自太阳能电池板的电力，并使用额外的电力为可充电电池充电。通过该系统，学生学习并掌握了多学科领域的关键概念和知识，包括数据采样和采集、模数转换、太阳能、电池充电、控制、嵌入式系统和软件编程。它是学生学习CPS可再生能源的宝贵教学资源。
Renewable energy sources such as solar and wind provide an effective solution for reducing dependency on conventional power generation and increasing the reliability and quality of power systems. Presented in this paper are design and implementation of a laboratory scale solar microgrid cyber-physical system (CPS) with wireless data monitoring as a teaching tool in the engineering technology curriculum. In the system, the solar panel, battery, charge controller, and loads form the physical layer, while the sensors, communication networks, supervisory control and data acquisition systems (SCADA) and control systems form the cyber layer. The physical layer was seamlessly integrated with the cyber layer consisting of control and communication. The objective was to create a robust CPS platform and to use the system to promote interest in and knowledge of renewable energy among university students. Experimental results showed that the maximum power point tracking (MPPT) charge controller provided the loads with power from the solar panel and used additional power to charge the rechargeable battery. Through the system, students learned and mastered key concepts and knowledge of multi-disciplinary areas including data sampling and acquisition, analog to digital conversion, solar power, battery charging, control, embedded systems and software programing. It is a valuable teaching resource for students to study renewable energy in CPS.
