  1. 1. Modeling, Control and Protection of Low-Voltage DC Microgrids

    Författare :Daniel Salomonsson; Lennart Söder; Brian K. Johnsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; circuit transient analysis; dc power systems; dispersed storage and generation; load modeling; power conversion; power distribution control; power distribution faults; power distribution protection; power electronics; Electric power engineering; Elkraftteknik;

    Sammanfattning : Current trends in electric power consumption indicate an increasing use of dc in end-user equipment, such as computers and other electronic appliances used in households and offices. With a dc power system, ac/dc conversion within these loads can be avoided, and losses reduced. LÄS MER

  3. 2. Waste-heat Recovery Using Thermoelectricity and Silicon Carbide Power Electronics

    Författare :Arash Edvin Risseh; Hans-Peter Nee; Torbjörn Thiringer; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermoelectricity; Power converter; Silicon Carbide; MOSFET; Power management; Thermoelectric generator; Renewable energy; Vehicle; Power electronic; Waste heat; Ultra-low inductance; Power module; Termoelektrisk energiomvandling; Kiselkarbid MOSFET; Effektomvandlare; Förnybar energikälla; Effektelektronik; Spillvärme; Effektmodul; Låg induktiv module; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Energy consumption in the world has increased continuously due to a growing population and increased energy consumption per capita. Moreover, the largest part of consumed energy still comes from fossil sources which in 2016 was more than 130 PWh. LÄS MER

  4. 3. Wind power in thermal power systems

    Författare :Lisa Göransson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; integration; wind power; variation moderator; PHEV; storage;

    Sammanfattning : AbstractWind power is a key technology in the effort to transform the power system in order to reduce its climate impact. However, the ability of wind power to reduce CO2-emissions depends on the properties of the power system. LÄS MER

  5. 4. Power control strategies for renewable energy systems : The inverter's role in future power systems

    Författare :Sara Anttila; Cecilia Boström; Sandra Eriksson; Lena Max; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Renewable energy systems; Grid-connection; Inverter; Power control; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Sammanfattning : Connecting more non-dispatchable renewable energy sources (RESs) will result in a higher power variability and a lower system inertia when the synchronous generators are replaced by inverter-connected RES. Inverter control can be divided in three categories: grid-following, grid-forming (GFM) and grid-supporting. LÄS MER

  7. 5. Accurate Leakage-Conscious Architecture-Level Power Estimation for SRAM-based Memory Structures

    Författare :Minh Quang Do; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SRAM Power Modeling; Deep Submicron; Power-Performance Estimation Tool; VLSI; Power Estimation; DSP Architecture; CMOS; Cache Power Modeling;

    Sammanfattning : Following Moore’s Law, technology scaling will continue providing integration capacityof billions of transistors for IC industry. As transistors keep shrinking in size, leakagepower dissipation dramatically increases and gradually becomes a first-class design constraint. LÄS MER
