Smart Grid enables a change to a sustainable energy system New political targets, with main focus on • Reduction of CO 2 emission • Energy efficiency • Renewable power generation • Reliability and security

Integration of renewable energy sources Challenge: Availability of emission free balance power Consumption Production Source: Sv. K Wind and Solar requires more balance power

Smart Grid enables balance by increased transmission capacity and integrated active consumers Planning targets for Sweden Wind 30 TWh, 12 000 MW Compare with Hydro Nuclear 16 000 MW 9 000 MW How to balance intermittent 12 000 MW wind? + Import / - Export Hydro Wind District heating Nuclear Electrical demand Source: Sv. K Sweden

Smart Grid enables peak load shaving by active consumers Benefits for network operator and energy supplier § Use more efficient production units § Use less costly production units § Use units with less emission § Improved utilization of the grid capacity § Load More available balance power Time Develop business models that transfers part of the profit to the consumers § New rules for the electricity market § Modified network regulation

Smart Grid components HVDC Light – new technology for DC-connections Bor. Win 1 § 400 MW § +- 150 k. V, 200 km cabel (sea & land) § Contributes to reduction of CO 2 emissions with about 1. 5 millioner ton/year § Supports wind power in Germany East West Interconnector § 500 MW § +- 200 k. V cabel (sea & land) § Customer: Eirgrid, in service 2012 § Supports wind power in Ireland

Smart Grid components: Bulk energy storage Energy storage § Voltage control § Increased stability § Used during peak load situations and as emergency reserve during power outages. Product concept § Li-on battery cells § 5 -50 MW, 5 min to 60 min § Modular concept

Smart Grid components: Integrated Active House and Electric Vehicle Home Energy Management System Benefits § Active ‘prosumer’ benefits from most favorable spot price § Peak load shaving by local production, storage and time shift of consumption § Overall reduction of energy consumption by increased consumer awareness

Smart Grid components: Charging infrastructure Electric Vehicles Billing system Benefits § CO 2 reduction § Allows for the possibility to dispose energy when excess production is available. § Peak load shaving Chargin g method Description Slow charging § Individual poles at home or parking lots § Charging time ~6 hours § ~2 k. W, , AC converters Fast charging § Special charging stations or with § ~20 k. W, AC converters Ultrafast charging § Concept for special charging stations § Charging time ~6 min Installation equipment at home § Charging time ~1 hour § >300 k. W, DC converters

R&D sites for Smart Grid From research to business § Research & Development: # New technology solutions # New business models # New market rules # New role of the customers and customer behaviors § Innovation: Transfer learning's into market rules and commercial applications § Education: Site for training and demonstration

Stockholm Royal Seaport – A world class sustainable city, with a Smart Grid as the enabler Objectives § Year 2030 fossil free § Year 2020 CO 2 -emissions below 1, 5 ton person § Adapted to future climate changes Focus areas § § Effective energy end-usage Environmental effective transports Local re-cycling Life style
