    Sammanfattning : An electrical distribution network supplies power to many households at a time. Each house has various types of electrical appliances which consume different levels of power depending on its function and the load it supplies. An ideal case would be when no appliances cause power disturbances, however, in reality, many electrical appliances (e.g. LÄS MER

  7. 30. Flexibilitetsåtgärder i uppvärmningssystemet: En undersökning om hur implementering av flexibilitetsåtgärder i uppvärmningssystemet kan reducera uppvärmningskostnaden
