ELECTRIC VEHICLES IN SMART GRIDS: INTELLIGENCE NEEDED Johann Hurink AVERE E-MOBILITY CONFERENCE
THE ENERGY TRANSITION TAKES PLACE IN THE DISTRIBUTION GRID! The direction of the electricity flow changes over time “Energy Turnover” EHV HV MV LV
Electric Vehicles in Smart Grids: Intelligence needed
13-4-2016
SUMMARY TRENDS
§ Electricity need will increase § Size of electricity production units will decrease - decentralized production § Controllability of electricity production will decrease § Amount of flexible consumption will increase § ‘Synchronization’ of generation will increase § ‘Synchronization’ of consumption will increase
àMay lead to stress in the distribution grid!!

ROLE OF ELECTRICAL VEHICLES IN SMART GRIDS • Charging an EV is a flexible load à Suitable for Demand Side Management • ‘de-synchronize’ charging of EVs • help to reduce e.g. PV- or Windpeak • An EV can be used as a battery!!

USE AN EV AS A BATTERY
• Integrate EV-charging into DSM • Use EV as battery if the EV is not used à Vehicle to Grid • Charge the EV during high PV or Wind peaks • Discharge the EV in periods of high load in the distribution grid à Vehicle to Home • Store surplus of local generated energy • Use energy at times with no local generation à Increase self consumption

NEEDED: CHANGE IN ENERGY MANAGEMENT
§ Energy Management Systems (EMS) needs to get also inside homes à Decentralized Energy Management (DEM) § Integrate smart appliances and EVs in homes à ‘Home Energy Controllers’ Integrate smart appliances and EVs in local grids à ‘GridControllers’ § The local systems have to be integrated to a global system
