This CAREER proposal aims to develop the foundations of a new research branch, namely, long-term electromagnetic-transient (EMT) simulations. Classically, EMT simulations have been employed to study the dynamic response of legacy grids for a few seconds. The new challenge is to simulate restoration processes of electric grids powered by converter-based resources (e.g., wind and solar) which can last from minutes to hours. This project will bring transformative advances to accelerate long-term EMT simulations by engineering special dynamic models and numerical approaches for converter-based electric grids. These advances are instrumental to address modern reliability requirements for EMT simulation tools. The intellectual merits of this proposal include the engineering of EMT models of transmission lines and renewable resources as well as a special numerical integration approach and its implementation using parallel computing. The broader impacts of the project include the development of 3D animations and virtual-reality representations of EMT phenomena, which will facilitate communication with the public, continuing education courses for industry, and engaging activities with high-school students. To accelerate EMT simulations, this project will achieve three research objectives. The first is to model three-phase transmission lines using lumped sections of non-uniform length which will be adjusted to minimize simulation errors with respect to a solution to the wave equation in time and space. The second is to engineer a state-variable numerical integration algorithm to solve differential algebraic equations (DAEs) while exploiting the linear and non-linear nature of the modeled transmission lines and converter-based resources, respectively. The third is to implement the DAE solver by exploiting graphics-processing-unit computations and a novel decomposition technique for the system dynamics. The education plan of this project consists of three objectives. The first is to develop 3D animations that have a positive impact on learning. The second is to leverage virtual-reality technology for personalized real-time interaction with EMT animations. The third is to disseminate the advances of this project via social media, continuing education courses, and interaction with high-school students.This 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.

该职业建议旨在开发一个新的研究部门的基础，即长期电磁透射式（EMT）模拟。从经典上讲，已经采用了EMT模拟来研究传统网格的动态响应几秒钟。新的挑战是模拟由基于转换器的资源（例如，风能和太阳能）提供动力的电网的恢复过程，这些电网可以持续时间为几分钟到几个小时。该项目将通过工程特殊的动态模型和基于转换器的电网格的数值方法来加速长期EMT模拟，从而加速长期EMT模拟。这些进步有助于满足EMT模拟工具的现代可靠性要求。该提案的智力优点包括传输线和可再生资源的EMT模型的工程，以及使用并行计算的特殊数值集成方法及其实施。该项目的更广泛的影响包括开发EMT现象的3D动画和虚拟现实表现形式，这将促进与公众的沟通，为行业的继续教育课程，以及与高中生的活动。为了加速EMT模拟，该项目将实现三个研究目标。首先是使用不均匀长度的集体截面对三相传输线进行建模，该截面将进行调整以最大程度地减少时间和空间中波动方程的解决方案的模拟误差。第二个是设计一种状态变量的数值集成算法来求解差分代数方程（DAE），同时分别利用建模传输线和基于转换器的资源的线性和非线性性质。第三是通过利用图形处理单元计算和针对系统动力学的新型分解技术来实现DAE求解器。该项目的教育计划包括三个目标。首先是开发对学习有积极影响的3D动画。第二个是利用虚拟现实技术来与EMT动画进行个性化实时互动。第三个是通过社交媒体，继续教育课程以及与高中生的互动来传播该项目的进步。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子和更广泛影响的评估评估标准通过评估来获得支持的。
