摘要

能源转型正在成为近年来的主要挑战之一,它需要快速发现新的技术和解决方案,以便有效地将可再生能源纳入电力系统。在这种情况下,孤岛式交流微电网是最有前途的架构之一,但它需要智能和先进的控制系统,以便在所有可能的运行情况下都能快速、稳健地运行。在先进的控制技术中,电力转换器的高阶滑动模式控制是最有前途的解决方案之一,因为它能够应对模型和参数的不确定性,而不会产生不连续的控制动作。这项工作介绍了理论论文中提出的方法的实验验证,其中定义了频率和电压控制器,结合了一次和二次经典调节的优势。实验活动在尼什大学电子工程系微电网和智能电网研究实验室进行。实验结果表明,变流器在正常运行情况下的控制行为是正确的,而且可以在发电机组之间没有任何通信基础设施的情况下管理运行模式之间的转换。

Frequency and voltage communication-less control for islanded AC microgrids: Experimental validation via rapid control prototyping
The energy transition is becoming one of the main challenges in recent years and it requires a fast discovery of new technologies and solutions to effectively integrate renewables in the electricity system. In this context, islanded AC Microgrids represent one of the most promising architectures, but they require smart and advanced control systems to allow fast and robust operations in all the possible operating scenarios. Among the advanced control techniques, Higher Order Sliding Mode control for power converters is one of the most promising solutions due to its ability to cope with model and parametric uncertainties without generating discontinuous control actions. This work presents the experimental validation of the approach proposed in a theoretical paper in which frequency and voltage controllers were defined that combined advantages of primary and secondary classic regulations. Such experimental campaign has been conducted at the Micro-grid and Smart-grid Research Lab of the Faculty of Electronic Engineering, University of Niš. Results show the correct behavior of the converters control in normal operation scenarios and the possibility to manage transitions between operating modes without any communication infrastructure among the generating units.
