  1. 1. Modular Multilevel Converters for Heavy Trucks

    University essay from Linköpings universitet/Elektroniska Kretsar och System

    Author : William Moberg; [2020]
    Keywords : MMC; Modular Multilevel Converter; VSC; BESS; BMS; IGBT;

    Abstract : This thesis examines alternatives for power supply for a heavy truck application based on five different modular multilevel converter configurations that ultimately feed a 3-phase motor. Advantages and disadvantages of the different configurations are being discussed as well as other important factors that play a role in what configuration that is beneficial for the intended application.

  3. 2. Key Performance Indicators for the monitoring of large-scale battery storage systems

    University essay from KTH/Energiteknik

    Author : Emeric Brun; [2019]
    Keywords : ;

    Abstract : In the context of the fight against climate change, the electricity sector is experiencing a complete renewal. Power grids are undergoing a transformation from centralized and unidirectional systems to multilevel and more integrated networks with, among others, the insertion of intermittent Renewable Energy Sources (RES) on the production side and with the emergence of new consumer behaviors on the demand side.

  4. 3. Study of an Isolated and a Non-Isolated Modular DC/DC Converter : In Multi-Terminal HVDC/MVDC grid systems

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

    Author : Ranjithh Raj Ram Prakash; [2019]
    Keywords : High power high voltage DC-DC converter; Isolated non-isolated DC-DC converter; HVDC MVDC interconnection; HVDC HVDC point-to-point link; Modular multilevel converter; Transformer driven MMC; Steady state transient DC fault analysis; High Power DC DC-omvandlare med hög spänning; Isolerad och icke-isolerad DC-DC-omvandlare; HVDC MVDC-anslutning; HVDC HVDC-punkt-till-punkt-länk; Modulär multilevelomvandlare; Transformatorstyrd MMC; Stabilitet DC felanalys;

    Abstract : För sammankoppling av multi-terminala HVDC-system med punkt-till-punkt kopplingar ärDC-DC-omvandlaren den enda möjliga sammankopplingen. Därför genomgår problemenmed spänningsmatchning och likspänningsströmbegränsning i högspännings DC-systemomfattande forskning samt ligger i fokus för denna avhandling. READ MORE

  5. 4. Performance Evaluation of Modular Multilevel Converters for Photovoltaic Systems

    University essay from Linköpings universitet/Elektroniska Kretsar och System

    Author : Arvind Balachandran; [2019]
    Keywords : Modular Multilevel Converters; Converters; Power Converters; Photovoltaics; Photovoltaic systems; Half-bridge MMC; MMC; Full bridge MMC; Full bridge modulation;

    Abstract : Modular Multilevel Converters (MMCs), over recent years, have gained popularity in high-voltage(HV) and medium-voltage (MV) applications due to their high reliability. Also, with the rapid growth of solar photovoltaics (PV) and energy storage systems, there is a high demand for efficient and reliable power converter solutions. READ MORE

  6. 5. Optimization of the Product Allocation in Warehouses

    University essay from Umeå universitet/Institutionen för matematik och matematisk statistik

    Author : Nathalie Jakobsson; Josefin Rudälv; [2018]
    Keywords : warehouse; product allocation; buffer; placement; simulation; article saturation; multilevel storage;

    Abstract : The purpose of this project was to investigate if an improvement of the time consumed to move goods in a specific grocery warehouse can be made by changing and adding factors to the current allocation model. After analyzing raw data collected from the warehouse and constructing new models, the factors of interest could be evaluated. READ MORE
