1. 1. Protection of HVDC Grids Against Blackouts (Simulation)

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

   Author : Amal Al-Ammari; Dinah Atchan; [2021]
   Keywords : High Voltage Direct Current HVDC ; Voltage derivative dv=dt algorithm; Traveling wave algorithm; PSCAD simulation; Multi-terminal grid; Fault detection; Threshold value; Offshore HVDC; DC breaker; Voltage collapse;

   Abstract : In the search for green energy to combat climatechange, a shift from conventional energy sources such as coal,oil, and nuclear towards Renewable Energy Sources (RES) isneeded. This shift poses a threat to the stability of the powergrids as RES do not contribute with rotating mass in the system. READ MORE

3. 2. Frequency Stability in Future Low Inertia Power Systems With Battery Support

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

   Author : Alessandro Bonetti; Emil Bergvall; [2021]
   Keywords : Battery power support; Frequency Containment Reserves; Fast Frequency Reserves; Low inertia; Renewable Energy Sources;

   Abstract : In the search for green energy to combat climatechange, a shift from conventional energy sources such as coal,oil, and nuclear towards Renewable Energy Sources (RES) isneeded. This shift poses a threat to the stability of the powergrids as RES do not contribute with rotating mass in the system. READ MORE

4. 3. Modelling and Dynamic Performance of Hydropower in Frequency Regulation : Modelling of Double Regulated Hydropower Turbines

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

   Author : Kristinn Arnar Ormsson; [2021]
   Keywords : Frequency Containment Reserves FCR ; Hydropower; Double regulated DR turbine; Non-linear modelling; Simulink.; Frekvensreserv FCR ; vattenkraft; dubbelreglerad DR turbin; icke-linjär modellering; Simulink.;

   Abstract : The frequency of the Nordic power system has been increasingly deviating outside the normal frequency band (50 ± 0.1 Hz) in the past two decades. In an effort to counteract this, the Nordic Transmission System Operators (TSOs) have proposed new and stricter requirements on the units participating in Frequency Containment Reserve (FCR) market.

5. 4. Comparison of fast frequency reserve strategies for Nordic grid frequency stability

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Alexander Ismael; [2020]
   Keywords : Fast frequency reserve FFR; FCR-D; ARISTO; reduced inertia; renewable energy transition.;

   Abstract :  How long would modern society cope with a power outage, what would happen to vital systems that we today take for granted in modern society. The Nordic electricity grid is facing a major shift where electricity production from non-renewable sources are to be replaced increasingly by renewable sources. READ MORE

6. 5. Fast Power Support of Electrical Batteries in Future Low Inertia Power Systems

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Elvira Niemelä; Lucas Wallhager; [2020]
   Keywords : Electrical Batteries; Frequency Containment Reserves; Inertia; Fast Power Support; Renewable Energy Sources;

   Abstract : To create more sustainable power systems, as well as achieve environmental goals, further integration of Renewable Energy Sources (RES) is essential. However, this may result in a power system more vulnerable to disturbances, since RES do not contribute to the system’s inertia. READ MORE
