Smart Metering Scenarios with Interoperability: Smart Metering Scenarios with Interoperability STEPHEN PATTENDEN TAHI INTEROPERABILITY GROUP


BASIC REQUIREMENTS: BASIC REQUIREMENTS SEND CONSUMPTION DATA BACK TO ENERGY SUPPLIER’S MANAGEMENT SYSTEM MUST HAVE EQUIPMENT THAT ANY ENERGY SUPPLIER CAN USE BASIC DATA METER ID TOTAL CONSUMPTION TIME OF READ (Frequency of read) (THESE DATA ITEMS MUST BE AN INDUSTRY STANDARD) REGULATORY CUSTOMER DISPLAY (ON METER)


BASIC REQUIREMENTS +: BASIC REQUIREMENTS + REQUIREMENTS FOR METER SENT TO METER (AT LEAST): SET FREQUENCY OF READ CONTACTOR ON/OFF AD-HOC READ? (SUCH COMMANDS MUST BE STANDARD)


BASIC METER REQUIRMENTS: BASIC METER REQUIRMENTS MUST MEASURE ELECTRICITY CONSUMPTION INPORT/EXPORT ACCORDING TO MID MUST HAVE ABILITY TO SWITCH OFF/ON POWER MUST COMMUNICATE RELIABLY OPTIONS FOR COMMUNICATION USE TELEPHONE NETWORK DIRECTLY GSM OR ANALOGUE LINE USE LOCAL BROADBAND NETWORK USE DEDICATED HOME SYSTEM NETWORK OR ANY FUTURE METHOD MUST HAVE SOME STANDARD COMMUNICATION PORT NO CONTACTING PARTS IE. OPTICAL OR SOME PROXIMITY RF METHOD


BASIC METER REQUIRMENTS: BASIC METER REQUIRMENTS MUST MEASURE ELECTRICITY CONSUMPTION INPORT/EXPORT ACCORDING TO MID MUST HAVE ABILITY TO SWITCH OFF/ON POWER MUST COMMUNICATE RELIABLY OPTIONS FOR COMMUNICATION USE TELEPHONE NETWORK DIRECTLY GSM OR ANALOGUE LINE USE LOCAL BROADBAND NETWORK USE DEDICATED HOME SYSTEM NETWORK OR ANY FUTURE METHOD MUST HAVE SOME STANDARD COMMUNICATION PORT NO CONTACTING PARTS IE. OPTICAL OR SOME PROXIMITY RF METHOD THIS IMPLIES THE USE OF A COMMUNICATION MODULE


METER DATA COMMUNICATION: METER DATA COMMUNICATION REGARDLESS OF COMMUNICATION METHOD - THE TRANSFER OF DATA BETWEEN METER AND ENERGY SUPPLIER MUST BE: RELIABLE – EVERY DATA ITEM MUST BE DELIVERED SECURE – THE DATA MAY ONLY BE SENT TO/SEEN BY ENTITIES (people, organisations, machines) THAT HAVE PERMISSION TO RECEIVE/SEE IT. TIMELY – ANY DELAY IN DATA TRANSMISSION MUST BE CLEARLY DEFINED IN SERVICE LEVEL AGREEMENTS (Relates to Quality of Service) Note: some methods of transmission are inherently less reliable than others. THE COMMUNICATION MODULE WILL COMMUNICATE VIA: RADIO (RF) WHICH MAY IMPLY GSM DIRECTLY TO SUPPLIER IMS OR WIFI, BLUETOOTH, ZIGBEE, ZWAVE TO SECONDARY COMMUNICATION DEVICE IN PREMISES - EG. RESIDENTIAL GATEWAY POWERLINE SO MUST BE CONNECTED TO MAINS COMMUNICATING WITH SYSTEM ON LV SUPPLY – EG. GSM CONCENTRATOR AT SUB STATION COMMUNICATING WITH SECONDARY COMMUNICATION DEVICE IN PREMISES – EG. RESIDENTIAL GATEWAY CABLE DIRECTLY TO ANALOGUE PHONE LINE OR SECONDARY COMMUNICATION DEVICE


COMMUNICATION MODULE: COMMUNICATION MODULE WHILE METER IS CERTIFIED MEASURING DEVICE, THE COMMUNICATIONS MODULE MAY NOT BE – IF THIS IS THE CASE IF CONTACTLESS - CAN BE CONSUMER FITTED (SENT BY POST) MUST BE ATTACHED TO METER BY SIMPLE LATCH OR MECHANISM THAT THE USER CAN UNDO TO REPLACE MODULE MUST BE A LIMITATION ON DURATION OF POWER SUPPLY TO CUSTOMERS IF MODULE IS REMOVED. (WITHOUT MODULE METER CANNOT BE READ REMOTELY) WHERE COMMUNICATION GOES VIA GATEWAY OR LOCAL NETWORK THERE NEEDS TO BE PROTECTION AGAINST BROKEN COMMUNICATION (EVENT ALERT IN CASE OF BROKEN COMMUNICATION, MODULE STORAGE OF CONSUMPTION DATA) MODULES CAN COMMUNICATE WITH OTHER DEVICES/METERS IN PREMISE TO ENABLE ENERGY MANAGEMENT AND OTHER APPLICATIONS MODULES MAY HOLD COST OF CONSUMPTION, HISTORIC AND REALTIME MODULES MAY BE INTEROGATED FOR THIS INFORMATION SUCH INFORMATION SHOULD BE IN STANDARD FORMAT.


BASIC + MORE DEVICES: BASIC + MORE DEVICES REQUIREMENT TO READ OTHER METERS? LIKELY TO USE HOME SYSTEM FOR COMMUNICATION WITH OTHER METERS (NOT A FUNCTION OF MODULE) REQUIREMENT TO USE TELCO SERVICES SUCH AS ADSL? HOW ACCESSED?


BASIC + MORE DEVICES: BASIC + MORE DEVICES REQUIREMENT TO COMMUNICATE AND CONTROL OTHER DEVICES? HOME APPLIANCES – WHITE GOODS SECURITY SENSORS HEATING SENSORS ENTERTAINMENT SYSTEMS (Leading to Telecare Systems)


BASIC + MORE DEVICES: BASIC + MORE DEVICES REQUIREMENT TO COMMUNICATE AND CONTROL OTHER DEVICES? HOME APPLIANCES – WHITE GOODS SECURITY SENSORS HEATING SENSORS ENTERTAINMENT SYSTEMS (Leading to Telecare Systems) REQUIREMENT FOR A RESIDENTIAL GATEWAY? Using RF to communicate with other devices.

AND OTHER SERVICE PROVIDERS


INTEROPERABILITY ASPECTS: INTEROPERABILITY ASPECTS THE BASIC REQUIREMENTS ARE: SIMPLE METER WITH COMMUNICATION MODULE – STANDARD COMMUNICATION I/F RELIABLE COMMUNICATION PATH TO ANY SUPPLIER’S SYSTEM STANDARD DATA FORMATS, ADDRESSING, COMMAND SET THIS DELIVERS SMART METER INTEROPERABILITY EXTENDED INTEROPERABILITY TO UTILISE RESIDENTIAL GATEWAY SET UP ENERGY MANAGEMENT SERVICES LINK TO OTHER DEVICES SHARE (SOME) DATA WITH OTHER SERVICE PROVIDERS (TELECARE, SECURITY, ETC..) USE ENTERTAINMENT SYSTEM FOR CUSTOMER DISPLAY CAVEATS MUST ENSURE THAT USING PATHS VIA HOME NETWORKS AND RESIDENTIAL GATEWAYS DOES NOT COMPROMISE REVENUE INFORMATION. MUST PROVIDE OTHER SERVICE PROVIDERS ACCESS AND ALLOW CHANGE OF SUPPLIER IT IS EXPECTED MOST SOLUTIONS WILL USE THE RESIDENTIAL GATEWAY APPROACH SINCE THE COMMUNICATION ASPECT WILL BE MUCH CHEAPER OR FREE. BUT THE “RESIDENTIAL GATEWAY” IS ILL DEFINED AT PRESENT.
