Abstract

The article delves into the challenges of using high-voltage alternating current (HVAC) and high-voltage direct current (HVDC) technologies in offshore wind power transmission. It introduces low-frequency alternating current (LFAC) technology as a more efficient solution. The focus is on hexagonal converters, which combine the advantages of modular multilevel converters and matrix converters. The paper presents a Lyapunov control strategy to overcome the limitations of traditional PI control in these complex, multi-input multi-output systems. Experimental results demonstrate the superior performance of the Lyapunov control strategy in managing unbalanced grid voltage conditions. The paper also highlights the mathematical modeling and stability analysis of the hexagonal converter system, making it a valuable resource for researchers and engineers in the field of power systems and renewable energy.
