Bidirectional Power Control Strategy for Super Capacitor Energy Storage System Based on MMC DC-DC Converter

Also Available Domains DC - DC Converters

Project Code :TEPGPS565


The main objective of this project is to employ a bidirectional power control strategy for Super Capacitor Energy Storage System Based on MMC DC-DC Converter.


This paper focuses on a super capacitor energy storage system based on a cascaded DC-DC converter composed of modular multilevel converter (MMC) and dual active bridges (DAB). The cascaded converter is called MMC-DAB for short. This paper analyzes the topology and modulation strategy of the system in detail. Taking into account the shortcomings of the traditional bidirectional power control strategy, this paper proposes a control strategy where the DAB module of each branch independently controls the voltage of the sub-module capacitor. The mathematical models of the traditional and the proposed control strategy are established. The stability of the two control strategies is analyzed and compared. Finally, a MW-level engineering prototype of the MMC-DAB energy storage system is designed. The performance of the proposed topology is validated through the MATLAB-based simulations.
