  1. 6. Battery Energy Storage Systems as an alternative to gas turbines for the fast active disturbance reserve

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Ludvig Wingren; Jonas Johnsson; [2018]
    Keywords : BESS; Energy Storage; Batteries; mFFR; Fast Active Disturbance Reserve; Gas Turbines; Technology and Engineering;

    Abstract : Power systems operate at a specific frequency and constantly require a balance between production and consumption of electricity in order to maintain the frequency within a certain interval. Larger frequency deviations can cause blackouts or damage equipment connected to the grid. READ MORE

  3. 7. Kan frekvensen av återkommande korsförlamningsfall hos häst minskas med en anpassad foderstat?

    University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Author : Timjan Åkerholm; [2018]
    Keywords : korsförlamning; ; häst; foder; glykogen; ;

    Abstract : Korsförlamning är en muskelsjukdom som kan drabba alla olika typer av hästar men är vanligast hos tävlingshästar och arbetshästar. De kliniska symptomen för korsförlamning är smärta, kramper och stelhet i musklerna som i värsta fall leder till en tillfällig förlamning främst lokaliserad i rygg och bakben. READ MORE

  4. 8. Increasing the profitability of a PV-battery system : A techno-economic study of PV-battery systems as resources for primary frequency regulation

    University essay from Uppsala universitet/Fasta tillståndets fysik

    Author : Forsberg Samuel; [2018]
    Keywords : Battery storage; Energy storage; Photovoltaics; Power system; Primary frequency regulation; Profitability; Renewable electricity; Self-consumption; Solar energy; Batterilager; Egenanvändning; Elnät; Energilager; Förnyelsebar elektricitet; Lönsamhet; Primärreglering; Solceller; Solenergi;

    Abstract : In order to handle the mismatch between photovoltaic (PV) electricity production and household electricity use, battery storage systems can be utilized. However, the profitability of PV-battery systems in Sweden is poor, and economic incentives for households to invest in such systems are therefore missing. READ MORE

  5. 9. A fatigue investigation in a Kaplan hydropower station operated in frequency regulating mode

    University essay from KTH/Energiteknik

    Author : Aron Tapper; [2016]
    Keywords : ;

    Abstract : Due to the increase of intermittent power in the Nordic grid the need for frequency regulation increases. Hydropower has the ability to respond fast to frequency changes in the grid and is the power source mainly used to regulate the frequency in the Nordic grid. READ MORE

  6. 10. Variations in the primary control availability : An investigation of market conditions’ influence on the FCR-N product

    University essay from KTH/Tillämpad termodynamik och kylteknik

    Author : Johan Mann; Kasper Dahlin; [2015]
    Keywords : Primary control; primary regulation; electricity market; FCR-N; Frequency Containment Reserve for Normal Operation; frequency control.;

    Abstract : The systematic implementation of intermittent energy production sources has made the energy system more volatile and unpredictable than ever before. This development increases the importance of balancing services, in particular the primary control. However, the current research that has been conducted on the primary regulation products is limited. READ MORE
