Balancing & Grid Stability
Keeping the grid at 50 Hz. Understanding Inertia, RoCoF, and Frequency Control.
Real-Time Frequency Control
Supply must equal demand at every second. If demand > supply, frequency drops. If supply > demand, frequency rises. Inertia resists this change, buying time for primary reserves (FCR) to activate.
Grid Controls
Simulate disturbances and system properties.
5 s
Lower inertia (more renewables, less rotating mass) makes frequency change faster.
