Chalmers University of Technology Smarta elnät vad är det? Ett smart elnät är ett smart system som använder el för att leverera energi till konsumenter med drivkraft att använda mer förnyelsebara energikällor och minska energiförluster. Med smarta elnät kommer nya tekniklösningar för användning av el där elkonsumenten får större inflytande exempelvis med timmätning av el och nya former av generering och lagring, som elfordon för både transport och energilagring. Ø flexibilitet och mångfald
Smart Grid - fundamentals Power is a snapshot of how much electricity an appliance consumes, or a power plant produces Kettle 2 000 W (2kW) Wind Turbine 2 000 000 W (2 MW) Nuclear reactor 1 000 000 000 W (1GW) Energy is power over time - how much electricity is consumed during the previous period? Kettles use a hour 2 kwh Annual production from a wind turbine 6 MWh Annual consumption Sweden 160 000 GWh (160 TWh)

Energy system in change The energy system is undergoing a major global change Ø Main driving forces are to meet the political climate and energy goals and to counteract with economic crisis. In Europe there are climate and energy goals with targets for 20/20/20/10 by 2020, and different long term targets by 2050 going for 100% renewables Ø Today major investments in new electricity generation from renewables and in the use of biomass-based thermal power using difficult fuels Ø New models for energy usage and storage are developed e.g. with electrical vehicles ü The Smart Grid developments facilitate this change!
