2. Paris, June 9th 2010 ADDRESS INTERNATIONAL WORKSHOP DSO and Active Demand Roleto ensure the distribution of electricity to operate, to maintain, to develop the electricity distribution network Stakesto provide transparent and non discriminatory access to all network users to operate the distribution network in a secure, reliable and efficient way Expectationsto improve network control: voltage stability, network overloads, congestions and quality of supply to improve network efficiency (network investment optimization, network losses) to improve network use: to facilitate penetration of renewable generation, Electric Vehicle, etc.. AD is part of the smart grid development AD Services voltage regulation and power flow control tertiary active power reserve smart load reduction to avoid “blind” load shedding

3. Paris, June 9th 2010 ADDRESS INTERNATIONAL WORKSHOP Need for Coordination between players 3 -to ensure that load/generation variations determined by AD market do not have impact on the network security and technical quality of supply - to avoid contradictory actions, e.g. opposite requests within the same area - by informing the other System Operators about AD applications which could have impact on their network operation and/or can be in conflict or jeopardize AD products already bought on the market - by being informed and validating every AD request in its area of responsibility Coordination is needed Coordination is done

4. Paris, June 9th 2010 ADDRESS INTERNATIONAL WORKSHOP 4 for service localization + technical validation needs, consumers “equivalent” from network operation point of view are grouped in Load Areas Load Areas can encompass: part or whole LV lines, one or more MV/LV substations, MV feeders, busbars... Macro Load Areas: aimed for the TSO needs (e.g. one or more HV/MV substations) Information available for market players Interaction with AD players: Needs I Location information: load areas published and updated by DSO/TSO

5. Paris, June 9th 2010 ADDRESS INTERNATIONAL WORKSHOP Interaction with AD players: Needs II 5 The need for Technical Validation of AD Services Ensure coordination between DSO and TSO Ensure stability of the services provided by DSO and TSO (Quality of Service should not decrease with AD, but even be improved!!) How is the technical validation process established? Interaction between Aggregator and DSO/TSO on service activation: Approval needed The concept of the Sensitivity Matrix, periodically updated by DSO/TSO The need for regulation in order to establish a transparent and non discriminatory framework

6. Paris, June 9th 2010 ADDRESS INTERNATIONAL WORKSHOP TSO SM Sensitivity Matrix: An overview 6 Definition based on DSO/TSO needs Sensitivity indexes given at load area level No DSO/TSO commitment, guidelines for facilitating approval Periodically updated by DSO/TSO available to market players DSO network and historical measurement database DSO algorithms and processes TSO coordination DSO SM TSO algorithms and processes

7. Paris, June 9th 2010 ADDRESS INTERNATIONAL WORKSHOP Interaction with AD players: Needs III 7 Delivering metering information to other players Meter registers certified consumption on 15’ basis Forwarded to other players Metering information used for: Service Assessment Settlement among participants Consumer monitoring (understanding)

8. Paris, June 9th 2010 ADDRESS INTERNATIONAL WORKSHOP DSO functional architecture

9. Paris, June 9th 2010 ADDRESS INTERNATIONAL WORKSHOP TSO Functional Architecture

10. Paris, June 9th 2010 ADDRESS INTERNATIONAL WORKSHOP Conclusions 10 The DSO and TSO functional architectures have been developed and presented  Next steps: architecture implementation development and test of prototypes for AD service provision, DSO/TSO will  provide consumers location information for service delivery  technically validate AD services requests  provide metering information to other players and to consumers (via Energy Box)
