  1. 6. Design and Control of Bidirectional Converters for DC Microgrids

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Gustav Eckerbom; Villiam Petermann; [2023]
    Keywords : ;

    Abstract : This study aims to summarize the design of two common types of bidirectional DC-DC convertersfound in microgrids, as well as use two distinct control methods for each converter and validate theirperformance. Microgrids are decentralized, small-scale power systems that can operateindependently of the main power grid and are an important solution in order to integrate moreintermittent energy sources, such as solar and wind power, into the energy mix.

    Abstract : One third of Sweden's total annual greenhouse gas emissions originate from the transport sector today and great changes are thus needed in order to reach the net zero emission target by 2045. One of the most important measures discussed is an increased electrification of the transport sector and a solution with potential to contribute to this transition is electric road systems (ERS), where vehicles are charged dynamically.
