Control of Modular Multilevel Converter(MMC) based HVDC application under unbalanced conditionsProject description: The main objective of the project was to develop an advanced control strategy, which was able to control both positive and negative sequence grid-injected current independently as well as an efficient modulation, capacitor balancing and circulating current control was developed for the MMC-HVDC during unbalanced grid conditions. Energy controllers were proposed in order to eliminate the unequal energy distribution among the converter.A systematic approach was introduced for the effective reduction of the sum capacitor voltage ripple.Finally, a small prototype was built to validate the designed simulated model with 2 published IEEE conference papers.
