  1. 1. Impact of power quality on PV performance of grid connected systems

    University essay from Högskolan Dalarna/Energiteknik

    Author : Ozaveshe Momoh; [2022]
    Keywords : Power quality; Power quality monitoring; Electricity grid transmission; Power quality and PV production; Power quality in developing countries; Reactive power; Grid connected systems; Power measurement;

    Abstract : The problem with the implementation of the PV generators is that majority of the UNDP offices are in developing and underdeveloped countries. Majority of these countries experience various problems with the power quality from the national electrical grid. READ MORE

  3. 2. Comparative Analysis of Several Designs of Modular Multilevel Converters with Interleaved Half-Bridge Submodules

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

    Author : Lingyu Chen; [2022]
    Keywords : Modular multilevel converters MMC ; interleaved half-bridge submodule; interleaved converters; power loss calculation; converter efficiency; converter dimensions; Modulära multilevel-omvandlaren; interfolierad halvbrygga submodul; interfolierade omvandlare; effektförlustberäkning; omvandlareffektivitet; omvandlardimensioner;

    Abstract : The Modular Multilevel Converter (MMC) is one of the most commonly used active converters in the high-/medium-voltage sector due to its many advantages such as high scalability, high efficiency, modularity and low harmonic contents. However, in low-voltage and high-current applications, classical MMC designs are not very economical. READ MORE

  4. 3. Analysis Of A Wave Power System With Passive And Active Rectification

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Ferdus Wahid; [2020]
    Keywords : WEC; Optimal damping coefficient; Power smoothing; Passive rectifier; Active rectifier; Buck converter; Bi-directional DC-DC converter; Flywheel; Battery; Bi-directional voltage source converter; Voltage source inverter;

    Abstract : Wave energy converter (WEC) harnesses energy from the ocean to produce electrical power. The electrical power produced by the WEC is fluctuating and is not maximized as well, due to the varying ocean conditions. As a consequence, without any intermediate power conversion stage, the output power from the WEC can not be fed into the grid. READ MORE

  5. 4. Study of a battery energy storagesystem in a weak distributiongrid

    University essay from Uppsala universitet/Elektricitetslära

    Author : Jonas Lindstens; [2017]
    Keywords : Battery energy storage system; BESS; Distribution grid; simulink;

    Abstract : The awareness of the problems with fossil energy sources have increased the past decades. To decrease the effects of the fossil fuels on the climate and the environment, the use of intermittent energy sources such as solar- and wind power are increasing. READ MORE

  6. 5. Connectors and Vibrations – Damages in Different Electrical Environments

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Tibebu Gissila; [2013]
    Keywords : Contact resistance; Electrical load; Fretting corrosion; Lifespan; Reliability; Vibration parameter.;

    Abstract : The assessment of failure mechanisms in electrical systems due to electrical connector in a vibrating media often relies on only one type of electrical environment, i.e. resistive load. READ MORE
