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

    University dissertation from Stockholm : KTH

    Author : Daniel Salomonsson; KTH.; [2008]
    Keywords : 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; TECHNOLOGY Electrical engineering; electronics and photonics Electric power engineering; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik Elkraftteknik;

    Abstract : 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. READ MORE

  2. 2. Power Electronics for Mitigation of Voltage Sags and Improved Control of AC Power Systems

    University dissertation from Institutionen för elkraftteknik

    Author : Marcio Magalhães de Oliveira; KTH.; [2000]
    Keywords : power electronics; power quality; voltage sags; voltage-source converters; Custom Power; FACTS; real-time simulations; solid-state devices;

    Abstract : The thesis deals with the application of compensators andswitches based on power electronics in AC transmission anddistribution systems. The objective of the studieddevices/equipment is the power flow and voltage control intransmission systems and the mitigation of voltage sags andmomentary interruptions to critical loads in distributionsystems.

  3. 3. Modelling Wind Power for Grid Integration Studies

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jon Olauson; Uppsala universitet.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wind power; Wind power modelling; Intermittent renewables; Variability; Integration or renewables; Reanalysis data; Power system studies;

    Abstract : When wind power and other intermittent renewable energy (IRE) sources begin to supply a significant part of the load, concerns are often raised about the inherent intermittency and unpredictability of these sources. In order to study the impact from higher IRE penetration levels on the power system, integration studies are regularly performed. READ MORE

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Minh Quang Do; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SRAM Power Modeling; Deep Submicron; Power-Performance Estimation Tool; VLSI; Power Estimation; DSP Architecture; CMOS; Cache Power Modeling;

    Abstract : 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. READ MORE

  5. 5. Factor Demand and Market Power

    University dissertation from Umeå : Umeå universitet

    Author : Magnus Sjöström; Umeå universitet.; [2004]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; demand and supply; dynamic factor demand; adjustment costs; bootstrap; panel data; market power; Nationalekonomi; SOCIAL SCIENCES Business and economics Economics; SAMHÄLLSVETENSKAP Ekonomi Nationalekonomi; Economics; nationalekonomi;

    Abstract : The objective of Paper [I] is to analyze potential effects on the Swedish forest sector of a continuing rise in the use of forest resources as fuel in energy generation. An increasing use of forest resources as an energy input may have effects outside the energy sector. READ MORE
