  1. Optimizing the EV electrical demand impact CIRED, Frankfurt, 9 June 2011 MESSIAS – PT – S5 – 0294

  2. Assumption • EV inevitability • RESULT • Each house will have at least one new electric device to plug-in, which alone represent a charge equivalent to a typical house in Portugal (3,45 kVA) • Characteristic • Possible off-peak charge • Opportunity • Increase the efficiency of the entire electrical system, flatting the load diagram MESSIAS – PT – S5 – 0294

  3. Adding EV to Generation demand • EV charge in today’s off-peak hours (lowest price) • Results • New peak • Unsustainable off-peak hours incentive New peak +20% Old peak -40% Winter load diagram • EV perfect distribution charge in night off-peak hours • Requirements • Comprehensive off-peak tariff schedule • Management charging systems -10% -40% Winter load diagram MESSIAS – PT – S5 – 0294

  4. Adding EV to Generation demand  • EV perfect distribution charge in night off-peak hours • Requirements • Comprehensive off-peak tariff schedule • Management charging systems Winter load diagram • Competitive day light charging points EV charge Summer load diagram Winter load diagram MESSIAS – PT – S5 – 0294

  5. Adding EV to LV network MESSIAS – PT – S5 – 0294

  6. Adding EV to a suburban residential area Network New peak • EV charge in today’s off-peak hours (lowest price) • Results • New peak • Unsustainable off-peak hours incentive • New asset investment (lowering utilization factors) Old peak • EV perfect distribution charge in night off-peak hours • Requirements • Comprehensive off-peak tariff schedule • Local management charging systems • Charge transfer (competitive day light charging points) EV charge MESSIAS – PT – S5 – 0294

  7. Adding EV to a suburban residential area Network New peak • Highest risk in low consumption areas than in already higher consumption areas Old peak High consumption residential area with two EV by customer EV charge Winter load diagram MESSIAS – PT – S5 – 0294

  8. TODAY’S LV CUSTOMERS BEHAVIOUR • Customers’ adherence to tariff incentives • Finding • Adherence not higher than new customers Poor incentive? Customer poor information? • Customers consumption and their tariff • Finding • 31% of LV customers would potentially benefit 1,8 M (31%) Customer doesn’t have information to perceive benefits! MESSIAS – PT – S5 – 0294

  9. Conclusion • EV an opportunity to increase the electrical system efficiency requiring: • Comprehensive tariff schedule to enable load management all day long; • Competitive day light charging points to take advantage of middle of day off-peak hours and postpone DSO investment; • Smart-grid • to empower customers to evaluate their consumption situation and perceive tariff benefits; • to support management charging systems and services; • to support DSO activities enabling prompt mitigation actions.
