3. Frankfurt (Germany), 6-9 June 2011 Iñigo Cobelo – Spain – RIF Session 4b – Paper 0865 3 Objectives  Analyse the effectiveness of Demand Response programs in the tertiary sector  Develop a demand response hardware/software platform that can unveil the possibilities of Demand Response

4. Frankfurt (Germany), 6-9 June 2011 Iñigo Cobelo – Spain – RIF Session 4b – Paper 0865 4 System architecture

5. Frankfurt (Germany), 6-9 June 2011 Iñigo Cobelo – Spain – RIF Session 4b – Paper 0865 5 System architecture  Customers have a commitment to participate (the response is automatic)  Control over central HVAC and lighting systems  Customer notification SMS email  Posibility to override the control action Before and during the execution

6. Frankfurt (Germany), 6-9 June 2011 Iñigo Cobelo – Spain – RIF Session 4b – Paper 0865 6 System architecture Local controller

7. Frankfurt (Germany), 6-9 June 2011 Iñigo Cobelo – Spain – RIF Session 4b – Paper 0865 7 Test Facilities  Three office buildings: Bilbao Sevilla Barcelona

8. Frankfurt (Germany), 6-9 June 2011 Iñigo Cobelo – Spain – RIF Session 4b – Paper 0865 8 Results (1/2)  The software proved robust  The cost and effort required to install and program the system in each of the three different buildings has been similar  The event override capability provides confidence to building operators  A Baseline calculation process is required for the settlement and billing: It introduces errors (around 5% in the quarter-hourly analysis) Historical data is required Different methods provide different results (depends on the building)  Comfort degradation was acceptable during the events  Building thermal simulations proved inaccurate

9. Frankfurt (Germany), 6-9 June 2011 Iñigo Cobelo – Spain – RIF Session 4b – Paper 0865 9 Results (2/2)  Particular event load curves: Bilbao Sevilla Barcelona

10. Frankfurt (Germany), 6-9 June 2011 Iñigo Cobelo – Spain – RIF Session 4b – Paper 0865 10 Conclusions and future work  Commercial facilities can provide automated response in an aggregated way  It is more cost effective to target bigger buildings with high HVAC load  The implementation of a program like the one tested on the project could bring interesting benefits to both electricity suppliers and distribution companies: Short term reduction of the investment requirement on transmission, distribution and generation infrastructure Greenhouse gas emission reduction Minimisation of transmission and distribution losses Increase in the amount of renewable resources that can be integrated in the network  These and other issues are being further analysed by ENDESA in the “Smart City Malaga” project http://www.smartcitymalaga.com/
