3 Registers of the technical capabilities of connected users/devices with an improved
network control system, to be used for network purposes (ancillary services) to increase a
better control of energy production and utilization.

4 Updated performance data on continuity of supply and voltage quality to inform connected
users and prospective users.

B Enhancing efficiency in day‐to‐day grid operation
1 Improved automated fault identification and optimal grid reconfiguration after faults
reducing outage times:

▪ Using dynamic protection and automation schemes with additional information where
distributed generation is present;

▪ Strengthening Distribution Management Systems of distribution grids.
2 Enhanced monitoring and control of power flows and voltages.

3 Enhanced monitoring and observability of network components down to low voltage levels,
potentially using the smart metering infrastructure.

4 Improved monitoring of network assets to enhance efficiency in day‐to‐day network
operation and maintenance (proactive, condition based, operation history based
maintenance).

5 Identification of technical and non‐technical losses through power flow analysis, network
balances calculation and smart metering information.
6 Frequent information on actual active/reactive injections/withdrawals by generation and
flexible consumption to system operator.
C Ensuring network security, system control and quality of supply

1 Solutions to allow grid users and aggregators to participate in an ancillary services market
to enhance network operation.
2 Improved operation schemes for voltage/current control taking into account ancillary
services.
3 Solutions to allow intermittent generation sources to contribute to system security through
automation and control.
4 System security assessment and management of remedies, including actions against
terrorist attacks, cyber threats, actions during emergencies, exceptional weather events
and force majeure events.

34 Network users/devices, to actively participate/be managed in network’s operations and energy
management must be characterized by adequate technical capabilities. Considering the active control and
demand‐response of Distributed Energy Resources (i.e. generators, controllable loads and storage) some
of the most relevant technical capabilities that have to be taken into account are: (i) Active – reactive
power capabilities (ii) Dynamic response, (iii) Electric storage capacity in terms of energy and power. For
example, referring to the renewable generators participation in the network voltage regulation or power
flows control, the generator reactive power capability curve and the other capabilities aforementioned,
are technical constraints that have to be managed.
