STATCOM Study: Voltage Stability Analysis
Advanced voltage stability enhancement through Static Synchronous Compensator technology for modern power systems
Project Overview
This comprehensive study addresses the challenges posed by the increasing complexity of interconnected power systems and the growing integration of renewable, non-synchronous power sources. These developments introduce significant difficulties in maintaining voltage stability and power quality. A sustainable solution to enhance voltage stability is the localized installation of a STATCOM. By improving grid voltage stability under varying network conditions, STATCOMs can enhance active power transfer capability. However, before implementing a STATCOM, its behavior must be thoroughly analyzed under specific network conditions at the point of interface. The main objective was to develop an RT model for the electrical power systems, structured into hierarchical blocks and configurations, to facilitate this analysis.
