  1. 1. Shortening time-series power flow simulations for cost-benefit analysis of LV network operation with PV feed-in

    Master-uppsats, Uppsala universitet/Elektricitetslära

    Författare :Claudio David López; [2015]
    Nyckelord :Power flow calculation; quasi-static; time-series; vector quantization; PV generation; low voltage grids; distribution networks; computational performance; execution time;

    Sammanfattning : Time-series power flow simulations are consecutive power flow calculations on each time step of a set of load and generation profiles that represent the time horizon under which a network needs to be analyzed. These simulations are one of the fundamental tools to carry out cost-benefit analyses of grid planing and operation strategies in the presence of distributed energy resources, unfortunately, their execution time is quite substantial.

  3. 2. "Men det får man väl inte säga i det här landet" : Ett experiment i politisk korrekthet

    Kandidat-uppsats, Uppsala universitet/Statsvetenskapliga institutionen

    Författare :Johan Floderus; [2015]
    Nyckelord :Political correctness; social desirability bias; deliberative democracy; rational agent; immigration attitudes; experimental design;

    Sammanfattning : The aim of this study is to quantify the extent to which political correctness, understood as an implicit social convention of restraint on public expression, operates within a community. Due to a scarcity of prior experimental research in the area, a new method was developed for the purpose of the study. LÄS MER

  4. 3. ANALYSIS, IMPLEMENTATION AND EXPERIMENTAL EVALUATION OF A PHASE SHIFTED PWM CONTROL SYSTEM FOR A MODULAR MULTILEVEL CONVERTER

    L3-uppsats, KTH/Elektrisk energiomvandling

    Författare :Juan Colmenares; [2011]
    Nyckelord :;

    Sammanfattning : Nowadays, it is problematic to connect only one power semiconductor switch directly to the grid due to the high voltage range. In order to solve this difficulty, a new type of power converter has been introduced as a solution in high power applications. LÄS MER

  5. 4. Buffer Management Strategies for Improving Plant Availability

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Anna Lindholm; [2009]
    Nyckelord :averaging level control; bottleneck; availability; buffer tanks; buffer management; Technology and Engineering;

    Sammanfattning : In an industrial plant availability is an important factor since increased availability often gives an increase of final production which in many cases means an increased profit for the company. It has been shown that good strategies for buffer management could increase the availability of an entire plant which motivates further research in this area. LÄS MER

  7. 5. Estimation of Vehicle Lateral Velocity

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Pierre Pettersson; [2008]
    Nyckelord :Technology and Engineering;

    Sammanfattning : For the performance of the Haldex Active Yaw Control, accurate information about vehicle's lateral dynamic is important. It is for practical reasons not possible to measure the vehicle's lateral velocity, wherefore this state has to be estimated. LÄS MER
