SGER: Intelligent Adaptive Control of Flexible AC Transmission System (FACTS) Devices in a Distributed Power Network Containing Turbogenerators - Resubmission

“柔性交流输电系统”（FACTS）设备是指快速开关功率半导体器件，用于电力系统中控制功率流和稳定电压。它们动作的分散性质可能导致一个FACTS设备与另一个FACTS设备之间以及系统中的FACTS设备与发电机之间的有害交互。目前，人们普遍缺乏对如何通过对更快的FACTS设备和更慢的发电机进行本地调制来系统地协调和稳定全系统动态的了解。非线性神经控制器提供了一种解决方案。本项目将评估基于不同自适应评论器设计的神经控制器在多机电力系统中两种不同类型的FACTS设备（一次一个）的初步应用。选择SGER形式的提案是因为这是基于新想法的初步工作，如果成功，结果将用于生成常规提案，该提案将进一步研究传统控制的发电机和多个神经控制的FACTS设备之间的相互作用。这项工作的意义在于：o研究益处：局部放置的神经控制FACTS设备可以提供系统范围的改进的电压支持和稳定性，因此，允许整个电力系统以更小的稳定裕度更有效地运行。o对社会的好处：经济运行的可靠和安全的电力系统符合国家利益。当电力需求超过可用供应时，通过增加相对便宜的智能神经控制器，每安装兆瓦（和美元）的设备产生更多的电力将是有益的。

"Flexible AC Transmission System" (FACTS) devices refer to rapidly switching power semiconductor devices, used in power systems to control the power flow and stabilize voltages. The decentralized nature of their actions may cause deleterious interactions between one FACTS device and another, as well as between FACTS devices and generators in the system. Currently there is a general lack of understanding as to how to systematically coordinate and stabilize system-wide dynamics via local modulation of the faster FACTS devices as well as the slower generators. Nonlinear neurocontrollers offer a solution.This project will evaluate the initial application of neurocontrollers based on different adaptive critic designs to two different types of FACTS devices (one at a time) on a multi-machine power system. An SGER form of proposal is chosen because this is preliminary work based on novel ideas, and if successful, the results will be used to generate a regular proposal which will further investigate the interactions between conventionally controlled generators and multiple neurocontrolled FACTS devices.The significance of this work lies in:o Research Benefits: Locally placed neurocontrolled FACTS devices can provide system wide improved voltage support and stability, thus allowing the entire power system to be operated more efficiently with a smaller stability margin.o Benefits to Society: Economically operated reliable and secure power systems are of national interest. When electricity demand exceeds available supply, it would be beneficial to produce more electrical power per installed Megawatt (and Dollar) of equipment, with the addition of relatively cheap intelligent neurocontrollers.
