Assumption

- Assuming the control center controlling 10 primarry

substations

- 250 buses in LV and MV

- 100% PMU coverage in MV and 25% in LV

- In case of network reconfiguration the Control

center may act on all MV switches

4. Field and Lab demonstrationUse Case mapping, KPIs

18/05/2016SLIDE 16

Use Case mapping and KPIs

• All use cases have been assigned to demonstrators

• Each use case has a set of Key Performance Indexes (KPIs) in order to evaluate the performance of the architecture (deliverable 7.1)

Field demonstrators

• Real loading/generation conditions

• real PQ issues

• real congestions

• Real amount of information exchanged

• Real components

Lab demonstrators

• “Real” “Realistic” (past data or collection of statistics)

• Tests with different time windows and simulation steps check different issues of PQ, congestions

• It is possible to introduce errors/issues in different parts of monitoring/control chain
