   Sammanfattning : The EU has proposed an ambitious goal to achieve widespread E-mobility in both the electrical and commercial sectors. To accomplish this, a substantial number of DC fast-charging stations must be built. LÄS MER

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

   Sammanfattning : Decreasing energy consumption has become increasingly important in recent times due to climate change. The average temperature is increasing across the planet, and with it, an increase in droughts and other climate disasters can be seen. There are multiple ways to decrease energy consummation, and one of them is to regulate the light in a building. LÄS MER

5. 4. Model predictive control in heating and cooling networks : A case study of an urban district in Stockholm

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :ANDERS SAMUELSSON; DANIEL STEUER; [2021]
   Nyckelord :;

   Sammanfattning : This work presents a model predictive control system for heating and cooling supply planning in an urban heating and cooling network. The control approach addresses the need for strategic operation of distributed production technologies and thermal energy storage in increasingly complex heating and cooling networks. LÄS MER

7. 5. Learning to Fly: Upgraded Aerodynamics and Control Surfaces

   Master-uppsats, KTH/Flygdynamik

   Sammanfattning : In recent times the unmanned quadcopter aircraft has been used for a widening range of applications, but for longer distances it still falls short of conventional airplanes in terms of energy usage. There exists hybrid configurations of unmanned aircraft which combine the mobility of quadcopters and the range of fixed-wing aircraft. LÄS MER
