Smart Metering in Smart Homes - P Kopff

  1. 1. Smart Metering in Smart Homes Dr Paul KOPFF Electricité de France
  2. 2. gatewaygateway gateway devicesdevices devices different home (automation) networks PSTN / xDSL networks service aggregator InterNet service provider service provider Sporadic access ? General architecture
  3. 3. I will disturb any preprogrammed automation scheme INTENTS: Energy Management Load Management Tariff Management … Other Value Added Services ? 00115.637 kWh Smart Power Meter Smart Appliances… The customer is THE unpredictable part of the system predefined data from utilities Our initial perspective
  4. 4. Seller service HH tariff PowerMeter owner service 00115.637 kWh alarm events teleinfo from power meter Domotic networks Other’s service Smart Home A simple example HH tariff service cooperates with Smart Home service Users do’nt have to bother !
  5. 5. Power Meter Owner CUSTOMER Smart HOME Power Meter Owner Consum. per Usage HH Tariff Seller Appliance installer Validated data Validated data Validated device driving Tariff alarms Consumption alarms Pricing Uses Automation Maintenance (different price / differing usage) Generalisation The @HOMium implies also many B to B interactions !
  6. 6. 2 implementation bundles - Serial Meter (RS232 port) - PseudoMeter (simulation) EURIDIS Bundle for the basic services and interfaces definition Others : basic test bundles EURIDIS project The power meter owner will provide the basic power metering services ! 000115.637 kWh EURIDIS TELEINFO Serial port : 1200 bauds 1 data frame per sec.
  7. 7. EURIDIS packages Services Interfaces
  8. 8. Subscribing to DataService the client gets all the data from a DataListener through the Data interface the Meter interface is for the implementations of various power-meters and simulations The Data Service Services Interfaces
  9. 9. The Data Service package fr.edf.euridis.services ; public interface DataService { public void addDataListener(DataListener dl) ; public void removeDataListener(DataListener dl) ; } package fr.edf.euridis.interfaces ; public interface DataListener { public void available(Data d) ; } New data frame arrived available(Data d)
  10. 10. Subscribing to WarpService the client gets data around an event of interest from a WarpListener for a GivenWarp this service is generically implemented in the Warp, Weft and Loom classes of fr.edf.euridis.implement The Warp service Services Interfaces
  11. 11. package fr.edf.euridis.services ; public interface WarpService { public GivenWarp add(int past,int future) ; public void remove(GivenWarp gw) ; } The Warp service past data future data Event of interest startRecording( ) available(Data[ ] past,Data[ ] future) recording( ) TRUE
  12. 12. package fr.edf.euridis.services ; public interface GivenWarp { public void addWarpListener(WarpListener wl) ; public void removeWarpListener(WarpListener wl) ; public void startRecording( ) ; public boolean recording( ) ; } package fr.edf.euridis.interfaces ; public interface WarpListener { public void available(Data[ ] past,Data[ ] future) ; } The Warp service
  13. 13. The events of interest could be simple metering events, like tariff change, overshot detection, etc. With every Watcher service goes a listener type interface for the client. It may start a given warp… metering events Services Interfaces
  14. 14. two client configurable events are defined for - load management client applications, - per use consumption evaluations etc. Their configuration follows the same model as the Warp service, with GivenLoad and GivenUse specs. configurable events Services Interfaces
  15. 15. firstOn( ) confirmedOn( ) firstOff( ) confirmedOff( ) LOAD constance constance load events The LoadListeners « hear » four different types of events :
  16. 16. USE variance constance firstUp( ) confirmedUp( ) USE firstDown( ) variance confirmedDown( ) constance use events The UseListeners « hear » four different types of events :
  17. 17. package fr.edf.overshotClient.implement ; public class RecordOvershot implements OvershotDetection { private GivenWarp w ; public RecordOvershot( GivenWarp gw ) { w = gw ; } public void triggered(int overAmp) { System.out.println("Overshot of " + String.valueOf(overAmp) + " A detected") ; if (! w.recording( )) w.startRecording( ) ; } } Overshot client
  18. 18. package fr.edf.overshotClient.implement ; public class LogOvershot implements WarpListener { public void available(Data[ ] before, Data[ ] after) { if (before != null) { System.out.println(String.valueOf(before.length) +" samples before the overshot") ; } if (after != null) { System.out.println(String.valueOf(after.length) +" samples after the overshot") ; } } } Overshot client
  19. 19. Conclusions Successful services will be REAL TIME They will be immediately responsive to all kinds of signals and also to the perturbative customer (who will not be bothered) The service providers community will dynamically manage rich local resources The services running in the gateways will also cooperate (B to B interactions) To achieve this, they will have to support a common standard tailored as a model of services : current best fit, OSGi ! In order to optimize the use of servers and access resources thus promoting cheaper offers to more potential customers
