Energy infrastructure resilience is a high priority research area as highlighted by recent and wide-spread power grid disruptions in the United States. This CAREER proposal aims to advance the study of chaotic grid disturbances and their mitigation through a deeper understanding of their underlying physics and characteristics considering high volumes of renewable energy. A major technical barrier to achieving truly sustainable and reliable power grids of the 21st century are the unknown electromagnetic incompatibilities from combining renewable energy technologies with fundamentally archaic, yet vital infrastructural components such as transformers and rotating machinery. Solid-state power converters are an enabler for many green technologies such as wind and solar power. However, when their volatile operation becomes entangled with certain types of grid disturbances, complex and chaotic fault signatures are likely to undermine grid operations. The project will 1) pioneer new analytical tools to reveal overlooked disturbance signatures influenced by renewable energy activity, 2) develop advanced protection and grid stabilization techniques to mitigate the impacts of chaotic disturbances and 3) reinvigorate much needed STEM-oriented educational resources to stimulate participation of K-12 and minorities into electrical energy related fields. This CAREER proposal will focus on two types of destructive and chaotic disturbance phenomena that have periodically occurred but have not been studied in a renewable energy rich environment: ferroresonance and geomagnetically induced currents. The project will answer fundamental questions of (i) how chaotic electromagnetic disturbances change their signatures and damping mechanisms in a high converter-based renewable energy environment, (ii) how to determine new safe operating limits of critical network components such as electrical machines and transformers, (iii) what system protection improvements can be made to correctly detect and suppress disturbances, and (iv) what grid design modifications should be done to reduce disturbance severity and outage risks. The study will first develop novel numerical models and analytical tools to explore, characterize and predict these disturbances under the largely ignored influence of solid-state converter dynamics. Secondly, numerical results will be validated through a small-scale experimental hardware model of a representative power grid with solid-state converters. Thirdly, new system protection technologies will be prototyped for enhanced disturbance detection and suppression. Ultimately, this project is aimed at de-risking the integration of sustainable energy technologies to realize a more robust, resilient and self-healing energy infrastructure for greater economic prosperity, health and living standards for societyThis award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

能源基础设施的弹性是高优先研究领域，正如美国最近和广泛的电网中断所强调的那样。 这项职业建议旨在通过更深入地了解其基本的物理学和特征来推动对混乱的网格障碍的研究及其缓解，考虑到大量可再生能源。实现21世纪真正可持续性和可靠的电网的主要技术障碍是将可再生能源技术与根本古老而重要但重要的基础设施组件（如变形金刚和旋转机械）相结合，而不是已知的电磁不兼容。固态电源转换器是许多绿色技术（例如风能和太阳能）的推动者。但是，当它们的挥发性操作与某些类型的网格干扰纠缠在一起时，复杂和混乱的断层特征可能会破坏网格操作。该项目将1）先驱新的分析工具，以揭示受可再生能源活动影响的被忽视的干扰特征，2）开发先进的保护和网格稳定技术，以减轻混乱干扰的影响，3）重现了众所必需的Stem型干扰性教育资源，以刺激K-12和少数族裔与电能相关领域的参与。这项职业建议将集中于已定期发生但尚未在可再生能源丰富的环境中进行研究的两种破坏性和混乱的干扰现象：Ferroresonance和Geomagnet诱导的电流。 The project will answer fundamental questions of (i) how chaotic electromagnetic disturbances change their signatures and damping mechanisms in a high converter-based renewable energy environment, (ii) how to determine new safe operating limits of critical network components such as electrical machines and transformers, (iii) what system protection improvements can be made to correctly detect and suppress disturbances, and (iv) what grid design modifications should be done to reduce disturbance严重性和中断风险。该研究将首先开发出新颖的数值模型和分析工具，以探索，表征和预测这些干扰在固态转换器动力学的影响下，在很大程度上被忽略的影响下。其次，数值结果将通过具有固态转换器的代表性电网的小规模实验硬件模型进行验证。第三，将对新的系统保护技术进行原型型，以增强干扰检测和抑制。 最终，该项目旨在使可持续能源技术的整合降低，以实现更强大，韧性和自我建立的能源基础设施，以实现更大的经济繁荣，健康和社会生活标准，这反映了NSF的法定使命，并通过基金会的知识优点和广泛的影响来评估NSF的法定任务，并通过评估有价值。
