Abstract

This paper presents an overview of the STATCOM as a solution for voltage quality problems related to the interconnection of fluctuating renewable energy sources to the power network. Stationary, dynamic and transient modes of operation with emphasis on low voltage ride-through (LVRT) operation are described and simulation examples are presented to illustrate the role of the STATCOM as the grid interface solution using the example of a wind farm. Experimental results verify the validity of the simulation results indicating that the STATCOM is a good candidate for grid interface of renewable energy sources with induction generators.
