  1. 6. Kraftvärmens förutsättningar för flexibel elproduktion i Sveriges elsystem - En kvalitativ analys

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Miljö- och energisystem

    Författare :Ylva Selander; Henrik Andersson; [2021]
    Nyckelord :Kraftvärme; flexibel elproduktion; systemtjänster; följsam värmeproduktion; Skåne; Danmark; CHP; Combined Heat and Power; flexible electricity production; ancillary services; flexible heat production; Skåne; Denmark; Technology and Engineering;

    Sammanfattning : This master thesis aims to investigate if and how Swedish Combined Heat and Power (CHP) plants can increase its flexibility in electricity production. This is examined through a combining analysis of technical, market-oriented and regulatory conditions for Swedish and primarily Skåne CHP plants, excluding autoproducers and industrial plants.

    Sammanfattning : The energy transition taking place in various parts of the world will have many effects on the current energy systems as an increasing amount of intermittent power supply gets installed every year. In Sweden, just as many other countries, this will cause both challenges and opportunities for today´s energy producers. LÄS MER

  5. 9. Kraftvärme - En förbisedd grundpelare i morgondagens förnybara elsystem

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Truls Martinsson; [2021]
    Nyckelord :Combined heat-and-power; ancillary services; inertia; reactive power; optimization; profitability; Technology and Engineering;

    Sammanfattning : The Swedish power system, similar to those of other European countries, is currently transitioning from fossil to renewable. Simultaneously the electrification and digitalization of societies all over the world sets high standards for the availability of power. As a result the power systems experience certain limitations and issues. LÄS MER
