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

WORKSHOP
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

WORKSHOP
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)

WORKSHOP
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

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:
Service Assessment
Settlement among participants
Consumer monitoring (understanding)

WORKSHOP
Conclusions
 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)
