Collaborative Research: Computationally Efficient Solvers for Power System SimulationMariesa Crow, Electrical Engineering, Missouri University of Science & TechnologyMaggie Cheng, Computer Science, Missouri University of Science & TechnologyShuwang Li, Applied Mathematics, Illinois Institute of TechnologyAbstract: Several recent advances in computational methods in a variety of fields have brought the goal of real-time dynamic simulation within reach. Unfortunately, many power system analysis tools do not use algorithms that implement state-of-the-art solution techniques due to the time lag of results percolating from one field to another. Therefore, there is a need to bring together the best of the mathematicians, computer scientists, and power engineers to solve realistic problems. In this project, computationally efficient solution methods will be synergistically developed and applied to the problem of achieving real-time power system simulation. Specifically, recent advances in computational science and theoretical computer science will be extended to the problem of electric power networks. Intellectual Merit: Real-time simulation has long been considered to be a grand challenge in electric power engineering. A realistically sized electric power network problem can generate hundreds of dynamic state variables and 50,000+ algebraic states. The computational complexity of some power system simulations has kept time domain simulation from being used in on-line decision making. If simulations could run in real-time, then power system operators would have situational awareness and could implement on-line control to avoid cascading failures. This tool will assist the operator with proactive measures to limit the extent of the incident, and can significantly improve power system reliability. This project will exploit the expertise and advances in areas of linear solvers from a variety of physical fields and will adapt them for use in power system simulation.Broader Impact: This project will provide an opportunity for educating a diverse STEM workforce in electric power systems, computer algorithms and applied mathematics. The PIs, the graduate students, and the post-doctoral fellow will enter into a close mentoring relationship that will include one-on-one instruction not only in computational methods, but also ethical research practices, communication skills, and international awareness. The results of this research will be incorporated into multiple graduate classes: Computational Methods for Power Systems andApproximation Algorithms. The PIs will also develop undergraduate course material and pre-college hands-on projects.

协作研究：电力系统模拟的计算高效求解器，电气工程，密苏里州科学技术大学Maggie Cheng，计算机科学，密苏里州科学与技术大学的计算机科学，应用数学，伊利诺伊州技术学院的应用数学研究所，技术研究所：在计算方法中的几种进步，在各种领域的计算方法中都实现了实时的仿真目标。 不幸的是，许多电源分析工具不使用实现最先进的解决方案技术的算法，这是因为从一个字段到另一个字段渗透的结果的时间滞后。 因此，有必要将最好的数学家，计算机科学家和电力工程师汇集在一起​​，以解决现实的问题。 在该项目中，计算有效的解决方案方法将是协同开发的，并应用于实现实时功率系统仿真的问题。 具体而言，计算科学和理论计算机科学的最新进展将扩展到电力网络的问题。 智力优点：长期以来，实时模拟被认为是电力工程中的巨大挑战。 实际尺寸的电力网络问题可以产生数百个动态状态变量和50,000多个代数状态。 某些电力系统模拟的计算复杂性使时间域模拟无法在线决策中使用。如果模拟可以实时运行，那么电源系统运营商将具有情境意识，并可以实施在线控制以避免失败。该工具将协助操作员采取主动措施，以限制事件的程度，并可以显着提高电源系统的可靠性。 该项目将利用各种物理领域的线性求解器领域的专业知识和进步，并将其适应用于电力系统模拟的影响。Broader的影响：该项目将为在电力系统，计算机算法和应用数学中教育多样化的STEM劳动力提供机会。 PI，研究生和博士后研究员将建立紧密的指导关系，不仅在计算方法中，而且还包括道德研究实践，沟通技巧和国际意识。 这项研究的结果将纳入多个研究生类别：电力系统的计算方法和附属算法。 PI还将开发本科课程材料和预科实践项目。
