GOALI: Optically Modulated Switching Transition and Switching Sequence Based Power Electronics Control for Next-Generation Power SystemsPROJECT SUMMARY: The objective of this project is to synthesize a power-electronics control for next-generation power systems based on optically-modulated active-gate control (OAGC) for modulating power-semiconductor-device (PSD) switching dynamics and sequence-based control for modulating evolution of PSD switching sequences. Our approach is twofold: Formulate a joint optimal framework integrating OAGC and SBC for dynamic control of electromagnetic (EM) emission, switching loss, and dv/dt and di/dt stresses of next-generation high-frequency power converters under transient and steady-state conditions while ensuring regulation under stability bound; Investigate the effectiveness of the control schemes using scaled experimental validation and detailed simulation. University of Illinois, Chicago will be supported in this approach, with regard to optical device epitaxial and fabrication efforts, by the GOALIE industrial partner. Combining OAGC and SBC, yields a radical and transformative systems control at device level while achieving complete isolation between the low-voltage control and the high-voltage power stages. This is achieved, using photonic control, by translating power-system and power-converter system-level performance and reliability issues (e.g. efficiency, EM noise, device stress) along with regulation and stability requirements into precise switching-transition and switching-sequence requirements. Synthesis of such a real-time joint optimal-control methodology is a key challenge considering the wide scale of the dynamics being controlled.The proposed control has applications for FACTS, HVDC, microgrid/DG, EM launch systems, solid-state power stations, electric ships, fly-by-light, pulse-power systems and fault control, motor drives, EV/HEV. Results of the research will be integrated into two power courses. The project will include 2 (supported) Ph.D., 1 middle-school, and 6 senior-design-undergraduate students.

目标：下一代电力系统的基于光调制开关转换和开关序列的电力电子控制项目摘要：该项目的目标是综合基于光调制有源栅极控制的下一代电力系统的电力电子控制（ OAGC）用于调制功率半导体器件（PSD）开关动态，以及基于序列的控制用于调制 PSD 开关序列的演变。我们的方法有两个：制定一个集成 OAGC 和 SBC 的联合最优框架，用于动态控制瞬态和稳态下下一代高频功率转换器的电磁 (EM) 发射、开关损耗以及 dv/dt 和 di/dt 应力。状态条件同时确保稳定约束下的监管；使用规模化实验验证和详细模拟来研究控制方案的有效性。伊利诺伊大学芝加哥分校将在光学器件外延和制造工作方面得到 GOALIE 工业合作伙伴的支持。将 OAGC 和 SBC 相结合，可在器件级实现彻底的变革性系统控制，同时实现低压控制和高压功率级之间的完全隔离。这是通过使用光子控制将电源系统和电源转换器系统级性能和可靠性问题（例如效率、电磁噪声、器件应力）以及调节和稳定性要求转化为精确的开关转换和开关序列要求来实现的。考虑到所控制的动态范围很广，综合这种实时联合最优控制方法是一个关键挑战。所提出的控制可应用于 FACTS、HVDC、微电网/DG、EM 发射系统、固态发电站、电动船舶、光传操纵、脉冲电源系统和故障控制、电机驱动、EV/HEV。研究结果将被整合到两门电力课程中。项目包括（资助）博士生2名、中学生1名、高设计本科生6名。
