Test Case: Modular SSSC and LCC-based HVDC Link Technical Synergies

Abstract

This paper assesses the technical benefits that series FACTS (Flexible Alternating Current Transmission System) devices can provide to support the technical challenges when LCC-based HVDC links are connected to weak nodes. A state-of-the-art Modular Static Synchronous Series Compensators (M-SSSC) application is studied in detail. The analysis is supported with a set of simulations in DIgSILENT PowerFactory®, comparing HVDC-LCC link performance with and without M-SSSC.
