Forecast thermal congestion: reinforcement avoidance or deferral
Unlocked with increased DSO ability
Primary use case for local flex today
Capacity allocation: better allocation and trading of capacity rights amongst connected parties
Fault levels and inertia: ensuring system strength under high DER deployments
Powerline loss: minimising losses through local balancing
Asset conditioning: maximising lifetime of assets
Networked microgrids: management of islandable, interconnected microgrids
Future use cases
