GOALI: Optically Modulated Switching Transition and Switching Sequence Based Power Electronics Control for Next-Generation Power Systems

项目概述：该项目的目标是合成下一代电力系统的电力电子控制，该控制基于光调制有源门控制（OAGC），用于调制功率半导体器件（PSD）开关动力学和基于序列的控制，用于调制PSD开关序列的演变。我们的方法是双重的：制定一个集成OAGC和SBC的联合最优框架，用于动态控制下一代高频功率变换器在瞬态和稳态条件下的电磁（EM）发射、开关损耗、dv/dt和di/dt应力，同时确保稳定界下的调节；通过规模实验验证和详细仿真来研究控制方案的有效性。在光学器件外延和制造方面，芝加哥伊利诺伊大学将得到GOALIE工业合作伙伴的支持。结合OAGC和SBC，可在设备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，通过将电力系统和电力转换器系统级性能和可靠性问题（例如效率，EM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顺序要求来实现的。综合这种实时联合最优控制方法是一个关键的挑战，考虑到被控制的动力学范围很广。所提出的控制适用于FACTS， HVDC，微电网/DG， EM发射系统，固态发电站，电动船舶，光控，脉冲电源系统和故障控制，电机驱动，EV/HEV。研究结果将整合到两门动力课程中。该项目将包括2名（支持）博士，1名中学生和6名高级设计本科生。

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.
