Advanced Control Techniques for High-Power Power Converters

Abstract

This paper offers a comprehensive review of the advancements in the domain of Solid Oxide Fuel Cells and Electrolyzers for Green Hydrogen Production. The review encompasses the exploration of various advanced control methods that have emerged as alternatives to traditional cascaded linear controllers, specifically for power converters in distributed generation systems and microgrids. The significance and functionalities of voltage source converters (VSCs) in these systems are elucidated, followed by a discussion on the dynamic performance limitations of linear controllers. The paper delves into the most notable advanced control methods, shedding light on their implementation principles, merits, and demerits. Furthermore, the paper touches upon the application of modelling methods apt for control and simulation of power electronic systems, emphasizing the benefits of non-linear modelling for controller design. The review also covers the state-of-the-art integrated switchedcapacitor and inductive power converters, providing insights into the utilization of transistor technology and various control strategies. By drawing comparisons and categorizing different converter technologies, the paper aims to present a holistic view of the current landscape and potential future directions in the realm of Solid Oxide Fuel Cells and Green Hydrogen Production.
