  1. 1. Generation Reliability for Isolated Power Systems with Solar, Wind and Hydro Generation

    University dissertation from Chalmers University of Technology

    Author : Jimmy Ehnberg; Chalmers tekniska högskola.; Chalmers University of Technology.; [2003]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik; elektronik och fotonik; Electrical engineering; electronics and photonics; Renewable energy; Stochastic modelling; Generation reliability; Isolated power systems; Solar power; Wind power;

    Abstract : This licentiate thesis deals with reliability issues for small isolated power systems. The focus is on power systems in remote areas based entirely on renewable energy sources. The sources investigated in this thesis are mainly solar and wind power; stochastic models for these energy sources are presented. READ MORE

  2. 2. 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

  3. 3. 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.

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

    University dissertation from Chalmers University of Technology

    Author : Minh Quang Do; Chalmers tekniska högskola.; Chalmers University of Technology.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektronik; Electronics; VLSI; CMOS; Deep Submicron; Power Estimation; Cache Power Modeling; SRAM Power Modeling; Power-Performance Estimation Tool; DSP Architecture;

    Abstract : Following Moore’s Law, technology scaling will continue providing integration capacity of billions of transistors for IC industry. As transistors keep shrinking in size, leakage power dissipation dramatically increases and gradually becomes a first-class design constraint. READ MORE

  5. 5. 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
