  1. 1. Relay settings for frequency derivative protection against islanding : Optimizing RoCoF-Hysteresis and Delay for the Swedish power grid: An investigation of relevant values

    University essay from KTH/Hälsoinformatik och logistik

    Author : Ahmad Safari; [2023]
    Keywords : Islanding; unintentional islanding; distributed energy resources; main grid; RoCoF; hysteresis; delay; Ödrift; oavsiktlig ödrift; distribuerade energiresurser; stamnät; RoCoF; hysteres; fördröjning;

    Abstract : This report addresses the parameter settings for a protective relay designed to safeguard a 15 kW wind turbine located in Rimbo, Norrtälje municipality, against unintentional islanding. This type of situation arises when distributed energy resources continue to supply local loads, even if the main grid has been unintentionally disconnected. READ MORE

  3. 2. An FPGA Based MPPT and Monitoring System : suitable for a photovoltaic based microgrid

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Rongpeng Zheng; [2019]
    Keywords : Microgrids; Monitoring System; Maximum Power Point Tracking MPPT ; Stand-alone Mode; Grid-connected Mode; FPGA; Verilog HDL.;

    Abstract : Microgrids containing photovoltaic (PV) cells and wind power gain more and more interest. These microgrids may work in stand-alone mode ("islanding") or be conncted to the main grid. In both modes of operation, power quality must be monitored and controlled. This report focuses on microgrids and aims to implement a monitoring system based on FPGA. READ MORE

  4. 3. Investigation of Power Grid Islanding Based on Nonlinear Koopman Modes

    University essay from KTH/Elektriska energisystem

    Author : Fredrik Raak; [2013]
    Keywords : controlled islanding; grid partitioning; power system monitoring; Koopman mode analysis; spectral graph theory;

    Abstract : To view the electricity supply in our society as just sockets mountedin our walls with a constant voltage output is far from the truth. Inreality, the power system supplying the electricity or the grid, is themost complex man-made dynamical system there is. It demands severecontrol and safety measures to ensure a reliable supply of electric power. READ MORE
