2. Motivation and Background
E-Energy Program funded by German Federal Ministery of Economics and Technology
Field trials in six model regions
Integration of DER
Future energy market places
Smart prosumers in smart grids
E-DeMa project focus
Automation of business processes
Innovative energy products
ICT based prosumer-side energy management
 Requires powerful meter data management systems

3. Scenario & Stakeholder Analysis – Status quo
Liberalization of metering business
Prosumers can choose
Metering service provider
Monthly bills
Variable tariffs
Challenges
Overburdened DSO as central data hub
Retailers have no incentives to offer variable tariffs (energy procurement acc. standard profiles)
Interruptible loads and distributed feed-in not utilized economically

4. Scenario & Stakeholder Analysis – Trends
Retailer procurement based on metering data and not SLP; use meter reads for forecast
Contracting of interruptible loads by DSO to defer grid expansion instead of emergency disconnects
Aggregators bundle interruptible loads and feed-ins from prosumers

6. Meter Data Management System Design
All roles need a set of core features
Specific roles need additional “value added services”
Data management for procurement/sales and billing
Data processing for distribution grid operations
Modular architecture
Extensible architecture
Coupled by service bus
Core Features
Provisioning, Collection & Delivery
Data Validation
Privacy & Confidentiality Protection
Service Bus
Upstream Systems
Data Processing for Distribution Grid Management Systems
Data Management for Billing & Charging
Procurement planning
Value-added Services
For
Technical Systems
Commercial Systems

7. MDM Core Features
Contract based provisioning, data collection, delivery
Contract based metering granularity (intervals, registers)
Delivery as required by upstream systems
Easier tariff or retailer change
Data validation
Contract and context based validation (e.g. outage, weather)
Invalid data triggers appropriate processes (e.g. estimation, meter check)
Privacy protection and confidentiality
Balancing of business needs with privacy requirements
Filtering according to principle of data minimization

8. MDM Value Added Services
Commercial valued added services
Optimized procurement with current meter data for retailers
Balancing of aggregator contracts for DSOs
Support for complex tariffs (time-, load-dependent …)
Flexible delivery to upstream billing systems
Technical valued added services
Insight into low-voltage distribution grid
Manage DER feed-in
Optimized grid planning to reduce CAPEX
Real-time operation in a closed-loop mode to reduce OPEX

9. Conclusion Meter data management is a central smart grid cornerstone
MDM systems offer core features and value added services for commercial and technical challenges
Loose coupling of modular architecture guarantees
extensibility to new requirements
flexible deployment for different market roles
