3 1. Need for Smart ing (1/2) Conventional /M s Smart s Through smart metering, utilities can provide customers with new value-added services, expanding the scope and interval of energy information available for system optimization and reducing the cost-to-serve 3

4 1. Need for Smart ing (2/2) Smart Home data Data, status House lectronic meter call Back-end System Smart meter Data, commands Back-end System Automatic Reading (AMR) Smart ing The distributed and intermittent nature of customer s loading/energy sources impact the control and management of energy. Smart metering is an infrastructure for two-way communication between customers and utility that enables AMR, Time of Use (TOU) Tariff, Demand Response (DR), Home Area Network (HAN), Outage Management, lectric Vehicle (V) charging / Renewable nergy (R) on-grid etc. These new energy management measures can support green initiatives and change the way customers interact with their electricity suppliers 4

5 2. Smart ing System - Overview Front-end system Back-end system Customer premise HDU A/C Comm. Module Comm. Module Data Concentr ator Comm. Network Head-end System Data Management System Billing & Servicing Management system Water Heater Comm. Module Site 1 Data Integration Bus Site 2 Site n Other Systems Web portal The smart meter functions as a gateway between the head-end system, home display unit and the home appliances. Via the data concentrators and the interface, energy data are collected and stored. The validated energy data are stored in the Data Management System (MDMS) before distribution to various parties and systems nergy data can be distributed to web portals, which can be reached by the customers and other parties within the energy market. In some countries, a centralized Data Register (MDR) is established to provide all parties with the same validated data on a central portal. The energy data are also distributed to other systems such as the Billing & Servicing Management System and Outage Management System 5

6 2. Smart ing System Smart s Comply with IC standard and other International standards (e.g. AS, ANSI) Import/xport kwh/kvah measurement, instrumentation profile and load profile 100A contactor for remote connection & disconnection and 40A contactor for load limiting Detachable compartment for different communication modules Optional communication modules for Gas / Water meters & Customer Display Unit WAN / LAN module for HAN (Home Area Network) 3G/GPRS Grid Net WiMAX GridStream RF Mesh Protocols of most used devices: IC IC61107 N (IC61107) DLMS MODBUS SCTM Manufacturer dependant protocols (e.g.: Wieser, MH, lster) 6

7 2. Smart ing System Interoperability ISSUS TO OVRCOM Limited life span of infrastructures, creating pressure on return on investment interoperability and interchangeability barriers to switch Distinction between smart connections smart meters communication data infrastructure/services physical connection Standardization is currently lacking Interoperability is the ability of a system to exchange data with other systems of different types. Complying with open standards is a basic condition, but is not sufficient to achieve the interoperability. International standards leave room for further configuration to function within various architectures Interoperability- 1st degree To ensure a first degree of interoperability, it is not sufficient for meters and components, etc. just to meet the agreed communications standards, which contain a wide range of functions, options and free data fields. Project specific companion specifications will be required to specify the standards and how to use free data fields A "pyramid" of standards: the top layer for the data models, those in the middle for data formatting and transaction definitions, and those at the bottom to define the use of various technologies on different (wired and wireless) communication media Interoperability - 2nd degree To reach a second and final level of interoperability, it is necessary to specify what behavior is expected in both normal conditions and abnormal conditions. This behavior can be laid down in functional requirement specifications based on use cases or other types of specification formats Agreed interoperability requirements should reduce risk that smart meters and devices are replaced for technical, rather than commercial reasons so encouraging healthy competition that drives up standards 7

Data Management (3/3) The Role of Data Management System (MDMS) versus the Role of nergy Data Management System (DMS) MDMS Specialized to manage very large volume of data and very large volumes of events at highest speed and lowest total cost Integrate and unifly several head-end systems Synchronize master data for systems with those back office applications that are the system of records for the respective master data Record for all Basic Interval Data (BID) collected Providing BID to applications Pre-processing BID (aggregations/ calculations) and providing pre-processed results to applications for optimizing performance and data volume xecuting consumption-pattern based V on BID DMS Support all kinds of nergy Capital Management Processes Manage selected (example: Industrial customer contracts) or limited volumes of data that was read from the MDMS Manage discrete meter readings Inform the MDMS on how to preaggregate and pre-calculate BID in order to get the "processing-relevant" data The system of records for all "processing-relevant " metering data xecute operations on Non-BID Load Profiles xecute business data based V on BID or discrete meter readings 10
