  1. 1. Local Voltage Control in Converter Based PV Generation

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Charlotta Sporre; [2024]
    Keywords : distributed generation; active network management; low voltage distribution network; delta control; voltage control; Technology and Engineering;

    Abstract : As the world is trying to rid itself of its dependence on fossil fuels, the need for renewable energy is rapidly increasing. In the power distribution network (DN), this takes the form of distributed generation (DG) from renewable sources, such as photovoltaic (PV) power production. READ MORE

  3. 2. Local voltage control in a low voltage grid with high photovoltaic penetration

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Joakim Bakklund; [2024]
    Keywords : Technology and Engineering;

    Abstract : This thesis examines how active power control (Volt-Watt control) and reactive power compensation (Volt-VAr control) can help limit voltage increases on the low voltage grid due to high photovoltaic (PV), installations. Due to the large increase in interest to install small scale PV-systems within residential areas the Distribution System Operator E. READ MORE

  4. 3. Photovoltaic hosting capacity study for a residential area in Uppsala using a synthetic low voltage network

    University essay from Högskolan Dalarna/Institutionen för information och teknik

    Author : Ikenna Mbah; [2023]
    Keywords : Hosting capacity; performance index; low voltage network;

    Abstract : With the growing acceptance of photovoltaic (PV) systems globally including Sweden, an increasing number of PV systems has continually been installed all through Sweden. In this study, a selected residential area in Uppsala Sweden is considered as a possible site for PV system installation. READ MORE

  5. 4. Ride through Capability of medium-sized Gas Turbine Generators : Modelling and Simulation of Low Voltage Ride through Capability of Siemens Energy's medium-sized GTG and Low Voltage Ride through Grid Codes requirements at point of connection

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Keywords : Gas Turbines; Synchronous Machines; Generators; Turbogenerators; Fault Ride Through FRT ; Low Voltage Ride Through LVRT ; Grid Codes; Frequency; Inertia; Generator Inertia; Power System; MATLAB; Simulink; Modeling; Excitation System; Automatic Voltage Regulator AVR ; Saturation Curve; Capability Curve; Load Angle; Siemens Energy.;

    Abstract : In order to reduce emissions and achieve sustainable energy systems, renewable energy is increasingly being integrated into the power grid. However, the integration of renewable energy into the grid poses several challenges, including maintaining a stable power supply under changing and unpredictable conditions. READ MORE

  6. 5. System impact of micro-production

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Annie Haraldsson; [2023]
    Keywords : Fault ride through; LVRT; micro-production; solar production; photovoltaics; fault simulation; network modeling; power system disturbances; PMU-registrations; fault analysis; Technology and Engineering;

    Abstract : The focus in this thesis has been active power from small scale solar production and what possible impacts an increased proportion of small scale production can have, in a larger context, during short circuit (SC) faults in the grid. The main research question prompting this work was whether active power from small scale solar pro- duction can help support voltages during SC faults, and meet LVRT-requirements in the RfG. READ MORE
