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)装置是指在电力系统中用来控制潮流和稳定电压的快速开关功率半导体装置。它们行动的分散性可能会在一个FACTS设备和另一个FACTS设备之间以及系统中FACTS设备和发电机之间造成有害的相互作用。目前普遍缺乏对如何通过对较快的FACTS装置以及较慢的发电机进行局部调制来系统地协调和稳定全系统动态的认识。非线性神经控制器提供了一个解决方案。这个项目将基于不同的自适应评论设计对多机电力系统上的两种不同类型的FACTS设备(一次一个)的神经控制器的初始应用进行评估。选择SGER形式的建议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建议，该建议将进一步研究传统控制的发电机和多个神经控制FACTS设备之间的相互作用。这项工作的意义在于：o研究好处：局部放置的神经控制FACTS设备可以提供系统范围内更好的电压支持和稳定性，从而使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关系到国家利益。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.
