EDP Objectives
•
•
•
•
Demonstrate concrete applications of distributed energy storage and energy management in the distribution grid creating
value for the distribution grid operator and enabling innovative business models and competitiveness / efficiency on the retail
side
Understand how EDP’s Smart Grid concept should evolve in order to facilitate referred applications
Develop business cases of the different distributed energy management and energy storage applications in order to determine
the optimal mix of applications in different scenarios (different grid contexts, penetration of distributed generation, etc.)
Understand what regulatory framework and policy developments should be promoted

SENSIBLE Use Cases
UC 1 - OPTIMIZING THE OPERATION OF STORAGE DEVICES IN THE MV NETWORK
The main goal is to manage MV distributed storage devices in order to solve technical problems at the MV network level (e.g.
degradation of voltage profiles, losses). The storage devices are assumed to have two objectives: (a) reserve capacity to support
continuity of service of an installation (or building) and (b) the residual capacity is used for grid support.
Grid operation
UC 2 - OPTIMIZING THE OPERATION OF STORAGE DEVICES IN THE LV NETWORK
The main goal is to manage local distributed storage devices in order to solve technical problems in the LV grid (namely related to
voltage issues) and minimize technical losses. The storage devices are to be coordinated with renewable generation at the LV level as
well as with demand side management schemes, considering residential storage and controllable loads.
UC 3 - ISLANDING OPERATION OF LOW VOLTAGE NETWORKS
The main goal is to enable the operation of LV networks in islanding mode, ensuring the secure transition to islanding operation and
the system stability, by providing adequate frequency and voltage regulation mechanisms.
UC 4 - MICROGRID EMERGENCY BALANCE
During islanding operation, the unbalance between LV generation and load will have to be minimized in order to avoid the
system collapse. The main objectives of this module are i) Minimize energy not supplied and time of service interruption; ii)
Ensure that the MG has sufficient capacity to ensure frequency regulation following islanding; iii) Maintain frequency

excursions within admissible limits.
UC 5 - FLEXIBILITY AND DSM IN MARKET PARTICIPATION
The scope is about LV customer flexibility market participation (wholesale and retail) and also regarding grid assess
management in case of grid operation optimization regarding investment deferral.
15
Extended Islanding
Added objectives:
 Maximizing continuity of service: Maximize the time the MV grid can operate in islanded mode
 Integrated management: Coordinated operation of storage units connected both at MV and LV levels; LV Grid supporting MV Grid in case of
severe voltage sags or in case of MV overhead line trip
 Quality-of-service: Ensure that voltage and current (THD) are maintained within limits
 Grid services: Ensure adequate reactive power dispatch
 Transient coordination between different storage systems at different levels: Ensuring a secure islanding transient
In case of contigency LV grid will
contribute with P and Q
