Abstract

Energy balancing of the alternate arm converter (AAC) is one of the major challenges due to the absence of continuous circulating current. Overlap period-based circulating current control methods are the most common methods for AAC energy balancing. In practical applications, component parameter variations of modular power electronics converters occur due to tolerances, component aging, and internal faults. Component parameter variation is a key consideration for energy balancing of all sorts of modular converters but has not been addressed in the existing literature for the AAC. This paper investigates the energy balancing capability of overlap period-based circulating current control methods in high-voltage direct current (HVDC) applications and proposes a compensation method to improve the energy balancing performance of the AAC under parameter variations. The effectiveness of the proposed compensation method is demonstrated through real-time simulation results based on an AAC HVDC model derived from the CIGRE benchmark modular multilevel converter model.
