ACTIVE DEMAND NETWORK OPERATORS ADDRESS INTERNATIONAL WORKSHOP TITLE OF THEDEMAND: THE FUTURE OF ELECTRICITY ACTIVE DEMAND NETWORK OPERATORS ADDRESS INTERNATIONAL WORKSHOP TITLE OF THEDEMAND: THE FUTURE OF ELECTRICITY ACTIVE SPEECH Giovanni Valtorta, Enel Distribuzione Paris, June 9 th 2010 reliability The research leading to these results has received funding from the European Community's Seventh Framework Programme (FP 7/2007 -2013) under grant agreement n° 207643

DSO and Active Demand Role • to ensure the distribution of electricity • to DSO and Active Demand Role • to ensure the distribution of electricity • to operate, to maintain, to develop the electricity distribution network Stakes • to provide transparent and non discriminatory access to all network users • to operate the distribution network in a secure, reliable and efficient way Expectations • to 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 • voltage regulation and power flow control • tertiary active power reserve • smart load reduction to avoid “blind” load shedding AD Services

Need for Coordination between players Coordination is needed - to ensure that load/generation variations Need for Coordination between players Coordination is needed - 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 Coordination is done - 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 3

Interaction with AD players: Needs I Location information: load areas • for service localization Interaction with AD players: Needs I Location information: load areas • 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) Consumer ID (point of supply code) xxxxxx Local Area Code yyyyy Macro Area code zzzzz Information available for market players • published and updated by DSO/TSO 4

Interaction with AD players: Needs II The need for Technical Validation of AD Services Interaction with AD players: Needs II 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 5

Sensitivity Matrix: An overview TSO coordination DSO network and historical measurement database DSO algorithms Sensitivity Matrix: An overview TSO coordination DSO network and historical measurement database DSO algorithms and processes TSO algorithms and processes • 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 SM available to market players DSO SM 6

Interaction with AD players: Needs III Delivering metering information to other players • Meter Interaction with AD players: Needs III Delivering metering information to other players • Meter registers certified consumption on 15’ basis • Forwarded to other players • Metering information used for: üService Assessment üSettlement among participants üConsumer monitoring (understanding) 7

Conclusions ü The DSO and TSO functional architectures have been developed and presented § Conclusions ü The DSO and TSO functional architectures have been developed and presented § Next steps: • architecture implementation • development and test of prototypes ü 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) 10
