Abstract

A transformless static synchronous compensator based on a modular multilevel converter is presented. Its principle of operation, dc link capacitors voltage balancing technique and control system are described in detail. To demonstrate the suitability of the proposed STATCOM and its effectiveness in medium/high voltage applications where converters with higher number of levels are required, several operating scenarios are considered, including reactive power support and flicker mitigation of offshore wind farms connected to the grid through ac submarine cable.
