1. 11. Development of a Real-Time Simulation Model in RSCAD of a STATCOM and its Control System

   University essay from Uppsala universitet/Elektricitetslära

   Author : Jessica Redander; Johanna Lenárd; [2021]
   Keywords : STATCOM; FACTS; Grid Forming; Control System; Modular Multilevel Converter; Voltage Source Converter; Power System; RSCAD; RTDS;

   Abstract : The development of interconnected power systems together with an increasing number of renewable non-synchronous power sources, create major challenges for the power system to meet the voltage stability and power quality requirements. One way to increase the voltage stability in a sustainable way is to locally implement a STATCOM. READ MORE

3. 12. 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.

4. 13. Analysis of Prerequisites for Connection of a Large-Scale Photovoltaic System to the Electric Power Grid

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

   Author : Fanny Lilja; [2021]
   Keywords : solar energy; large-scale photovoltaic system; PV; Swedish power system; power output fluctuations; voltage quality; voltage variations; reactive power compensation; PSS E; solenergi; storskalig solcellsanläggning; PV; Sveriges kraftsystem; effekförändringar; spänningskvalitet; spänningsvariationer; reaktiv effektkompensering; PSS E;

   Abstract : The deployment of large-scale photovoltaic (PV) systems is rising in the Swedish power system, both in quantity and in system size. However, the intermittent characteristics of the PV production raises questions concerning the stability in the electric power grid, and power output fluctuations from the PV systems can lead to voltage quality issues.

5. 14. Sustainable Implementation of Photovoltaic Technologies in Mauritius : A study on the energy system in Mauritius and the effect of solar power generation on frequency stability

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Maria Isabel Bang Jensen; Simon Lundberg; [2020]
   Keywords : Isolated energy system; photovoltaic technologies; frequency stability; system inertia; grid readiness; renewable energy; sustainable energy mix; Mauritius; PV shutdown; N-1 security; Isolerad energisystem; solceller; frekvensstabilitet; svängmassa; förnybar energi; hållbar energimix; Mauritius; produktionsbortfall; N-1 säkerhet;

   Abstract : Mauritius is an isolated island with ambitious targets for renewable energy generation and plans to invest in more solar power. The aim of this study is to assess how the implementation of photovoltaic technologies might affect the frequency stability in Mauritius and thus assess whether solar power can help the country obtain their targets for green energy generation.

6. 15. Developing Verification Models for Corona Discharge Suppression in High Voltage Capacitor Banks

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

   Author : Mohammadjavad Javadi; [2020]
   Keywords : Corona discharge; Suppression ring; High voltage capacitor banks;

   Abstract : Due to the universal considerable population and economic growth rate, demands for energy have risen significantly over the past decade. This means that the integration of renewable energies in the power grid has escalated as well as requests for reactive power compensation, voltage stability, and mitigation of harmonic filters.
