APPLICATIONS OF DISTRIBUTED FLEXIBLE AC TRANSMISSION SYSTEM (D-FACTS) DEVICES IN POWER SYSTEMS
Abstract
ABSTRACT
Distributed Flexible AC Transmission System (D-FACTS) devices offer many potential benefits to power system operations. This research examines the impact of installing D-FACTS devices by studying the linear sensitivities of power system quantities such as voltage magnitude, voltage angle, bus power injections, line power flow, and real power losses with respect to line impedance. Using these linear sensitivities, nonlinear problems such as real power loss minimization and voltage control may be solved; these applications are discussed in this project. The rapid development of power electronics technology provides exciting opportunities to develop new power system equipment for better utilization of existing systems. Such as enhancing the security, capacity and flexibility of power transmission systems. FACTS solutions enable power grid owners to increase existing transmission network capacity while maintaining or improving the operating margins necessary for grid stability. Supply of reliable, high-quality electrical energy at a reasonable cost is at the heart of the nation's economy. The electric power system is one of the nation's important infrastructures. The electric utilities provide pen access to the transmission system have mandated these changes. Several advanced methods are developed for maintaining a high degree of power quality and reliability under a deregulated environment. In the transmission system, a new method of achieving this control is through the use of power electronics based Flexible AC Transmission System (FACTS) devices. This paper provides a comprehensive guide to FACTS, covering all the major aspects in research and development of FACTS technologies. Various real-world applications are also included to demonstrate the issues and benefits of applying FACTS. The objective of this project is to create a multi-institutional power curriculum to address this new environment and technologies.
