An Integrated Approach to Enhancing Inter-Area Power Transmission in AC-DC Power Systems through FACTS and HVDC Integration

Abstract

It’s presents an integrated approach for optimizing power transmission in inter-area networks by effectively employing Flexible AC Transmission Systems (FACTS) and High-Voltage Direct Current (HVDC) technologies within AC-DC hybrid power systems. As the demand for efficient and reliable power transmission grows, the synergy between FACTS and HVDC becomes crucial to enhance system stability and transfer capability. This study proposes a unified strategy that combines the capabilities of FACTS devices, such as phase-shifting transformers and static var compensators, with the advantages of HVDC transmission, including long-distance transmission and independent control of active and reactive power. By strategically placing FACTS devices and HVDC links, the proposed approach aims to improve power flow control, voltage stability, and transient stability while minimizing transmission losses. The effectiveness of the unified strategy is demonstrated through simulation studies on a representative inter-area power system. The results highlight the potential benefits in terms of enhanced power transfer capacity, reduced line congestion, and improved system resilience. This research contributes to the development of advanced solutions for the optimization of inter-area power transmission in modern AC-DC hybrid power systems.
