1. 21. Closed-loop control and data- recording of a modular-multilevel converter (MMC)

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

   Author : Longgang Su; [2022]
   Keywords : Modular multilevel converters MMCs ; filed programmable gate array FPGA ; direct memory access DMA ; energy closed-loop control; data recording; ethernet.; Modulära multilevel-omvandlare MMC ; filed programmeable gate array FPGA ; direkt minnesåtkomst DMA ; energistyrning med sluten slinga; datainspelning; ethernet.;

   Abstract : Modular multilevel converters (MMCs) are the preferred converter solution in flexible ac transmission systems (FACTS) and high-voltage direct current (HVDC) applications. This is due to the high quality of the voltage and current signals, lower overall losses, and fewer problems with switching-related EMI. READ MORE

3. 22. Mechanical design guidelines and criteria for mooring components in wave energy devices : Finding the optimum chain and shackle parameters

   University essay from Uppsala universitet/Tillämpad mekanik

   Author : Arvin Modiri; [2022]
   Keywords : Chain; shackle; finite element method; wave energy converter; WEC; Kedja; kätting; schackel; finita element metoden; vågkraftverk;

   Abstract : Obtaining the perfect renewable energy source is one of the most important questions of our lifetime. One renewable energy source that could be of interest in this question because of the characteristics of the power that could be extracted from it is wave energy. READ MORE

4. 23. Design of radio frequency energy harvesting system : for use in implantable sensors

   University essay from Linköpings universitet/Elektroniska Kretsar och System; Linköpings universitet/Tekniska fakulteten

   Author : Amir Ebrahimi; David Kihlberg; [2022]
   Keywords : RF energy harvesting; RF rectifier; efficiency; voltage sensor; voltage doubler;

   Abstract : Implantable biomedical wireless sensors provide monitoring of vital health signs such as oxygen, temperature and intraocular pressure and may help to analyse and detect diseases in humans and animals. However, one of the design challenges of implantable devices is providing a safe and reliable energy source. READ MORE

   Author : Magdalena Borenäs; [2022]
   Keywords : ;

   Abstract : Fresh water scarcity is a problem that is becoming increasingly important to solve. There areseveral geographical locations around the world that suffer from a shortage of clean water. In South Africa, there are daily rations on how much water a household is allowed to use. READ MORE

6. 25. Frequency Stability of Power Electronic Based Power System with 100% Renewable Energy.

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

   Author : Abdullah Albalali; [2022]
   Keywords : energy storage; frequency control; synchronous generators; distributed power generation; virtual synchronous machine VSM ; PSCAD.; energilagringssystem; frekvenskontroll; synkrona generatorer; distribuerad kraftproduktion; virtuell synkron maskin; PSCAD.;

   Abstract : The modern power system is aiming to progress away from conventional synchronous machine  based power generation towards converter dominated system that leads to extensively high penetration of renewable energy such as wind and PV. This transition of modern power system toward converter based renewable energy comes with new challenges as the conventional synchronous generation is being replaced by converter based power system (CBPS).
