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

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Longgang Su; [2022]
   Nyckelord :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.;

   Sammanfattning : 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. LÄS MER

4. 3. Evaluating the performance of a vibration energy harvester under complex excitation

   Master-uppsats, Mittuniversitetet/Institutionen för elektronikkonstruktion

   Författare :Zhiqiang Chen; [2020]
   Nyckelord :Vibration energy harvesting; harvester; closed-loop control; resonant frequency; prediction;

   Sammanfattning : In recent years, vibration energy harvesting has become a research hotspot in the field of energy harvesting.

5. 4. Detection of lithium plating in lithium-ion batteries

   Master-uppsats, KTH/Kemiteknik

   Författare :Carl Johan Björkman; [2019]
   Nyckelord :Lithium plating; Batteries; Battery monitoring; Battery charging; Battery ageing; Litiumplätering; Batterier; Batteriövervakning; Batteriladdning; Batteriåldring;

   Sammanfattning : With an increasing demand for sustainable transport solutions, there is a demand for electrified vehicles. One way to store energy on board an electrified vehicle is to use a lithium-ion battery (LIB). This battery technology has many advantages, such as being rechargeable and enabling reasonably high power output and capacity. LÄS MER

7. 5. Impact of Wind Farm Control Technologies on Wind Turbine Reliability

   Master-uppsats, Uppsala universitet/Elektricitetslära

   Författare :Julia Walgern; [2019]
   Nyckelord :Offshore wind farm; wind turbine yaw control; operation and maintenance; reliability; wake redirection control; closed-loop control; active wake steering control; O M simulation tool;

   Sammanfattning : Cost efficient operation and maintenance strategies are crucial for reducing cost of wind energy. Since the regime change from feed-in tariffs to an auction-based bidding system for capacity in most European wind projects, levelized cost of energy is challenged constantly. LÄS MER
