Dynamic Stability Improvement of PMSG-Based Wind Turbine Generators Fed to a Power System Using PID controller Based STATCOM

Abstract

This paper presents the stability-improvement results of four parallel-operated offshore wind turbine generators (WTGs) connected to an onshore power system using a static synchronous compensator (STATCOM). In this project have the fast advance of high-capacity power-electronics technology, large commercial wind turbine generators can be practically employed to contribute high generated power to power systems, where wind PMSGs with full back to-back converters have proven to be good choices for high-power WTGs. Basically, the grid side converter of the PMSG-based WTG can be operated as a STATCOM.
