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. Study Of Universal Islanding Detection Techniques In Distributed Generation Systems

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

   Author : Ochai Ochalla Danladi; [2023]
   Keywords : Distributed Generation; Islanding; Quality Factor; Resonance Frequency; Low Voltage; Medium Voltage; Electronic Power Converter; Inverter;

   Abstract : Energy security, global warming, and climate change have been a major source of global discussions and development. Likewise, the rising cost of electricity for consumers and exponential demand for energy are major factors driving the incremental growth and integration of sustainable forms of energy generation into power the system cycle.

4. 3. Microgrid Protection Strategies for the Swedish Power System

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Zalak Shah; [2023]
   Keywords : Microgrid; Protection; three-phase fault; earth fault; Technology and Engineering;

   Abstract : This thesis mainly focuses on the protection strategies of microgrids for the Swedish power system in the medium voltage distribution system and specifically on the three-phase fault and earth faults protection strategies. For the analysis of both faults, different grid-connected, and islanding operations are simulated using DIgSILENT Power Factory. READ MORE

5. 4. Resynchronisation of Islanded Power Systems

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

   Author : Emelie Frost; [2020]
   Keywords : ;

   Abstract : The electricity demand and need of renewably produced electricity has increased the interest in locally produced electricity, also called distributed generation. The increase of distributed generation increases the risk of islanding, a state when a part of the grid has been electrically isolated. READ MORE

6. 5. Anti-Islanding Protection in Distribution Grids

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

   Author : Jianan Zhang; [2019]
   Keywords : ;

   Abstract : The growing number of distributed generation in the electrical system increasesthe risk of unintentional islanding. Power system islanding is the eventthat a part of the grid is continuously powered by the distributed generation,while it is already electrically separated from the power grid[1]. READ MORE
