Table 2 Frequency and control/protection actions
From: Microgrid dynamic security considering high penetration of renewable energy
Frequency deviation | Condition | Action |
|---|---|---|
∆f1 (0.3 Hz) | No contingency or load event | Primary Control |
∆f2 (1 Hz) | Generation /Load event | Secondary Control |
∆f3 > (2 Hz) | Large Separation event | Protection operation |
