1.3. Scope and Objectives of Use Case

ScopeDefines the main DSOs standards and actions to ensure a safe and reliable grid management when grid is in red state
Objective(s)To properly adjust power consumption/production by triggering the utilization of the available flexibility loads without market involvement when grid is in red (emergency) state
Related business case(s)Related to UC-7 "Ancillary services provision by STATCOM to TSO for overlay network stability"

1.4. Narrative of Use Case

Short description

DSO continously monitors the grid network condition and if an emergency (red state) situation is detected, aggregated flexibility from prosumers is activated based on bilateral contracts.

Complete description

DSO continously monitors voltage level and maximum load at each MV/LV line and transformer. If certain thresholds according to EN 50160 are reached (under/over-voltage), the grid network enters the red state and the flexibility loads available in the area on the same LV line will be used. In particular, activation of flexibility will be requested, either directly or through the aggregator on the basis of bilateral contracts, in order to stabilize the network. Local Electricity Market operations are paused (P2P trading, trading to external markets) until the issues have been resolved.
