Grid Services Control
FCR/aFRR/Voltage Support Control Room
This control room view models real-time frequency regulation, voltage support, and reserve services. It visualizes the end-to-end control loop — from grid signals to algorithmic dispatch to BESS response — including event logs and performance compliance.
What it visualizes
- •grid frequency and tolerance band monitoring
- •service allocation across FCR/aFRR/voltage/reactive/reserve
- •control loop latency breakdown and response time KPIs
- •event log with activations and stabilization actions
- •ancillary services accuracy and penalty risk indicators
- •resilience capabilities (islanding, black-start, autonomous failover)
Used for
- •operating ancillary services with audit-ready performance evidence
- •validating response-time constraints and redundancy logic
- •minimizing penalty exposure through compliance monitoring
