Curtailment Management
- Victoria Bruny
This module facilitates the user to interface with the power curtailment block that governs the power distribution between the wind-turbine (WT) and photo-voltaic (PV) generation systems. This block is part of the microgrid library from the OP1420, and should be used along with the other blocks.
Mask and Parameters
PVGS and WTGS parameters Tab
The same parameters are defined for the PG generation and WT generation.
Name | Unit | Description |
|---|---|---|
Trip time delay | s | Apply a time delay to the generator trip signal in seconds. |
Minimum curtailment power | pu | Specify the minimum power in per-unit that can trigger the curtailment signal. |
Maximum curtailment power | pu | Specify the maximum power in per-unit that can trigger the curtailment signal. |
Curtailment signal time delay | s | Apply a time delay to the curtailment signal in seconds. |
Minimum power difference deadzone limit | pu | Specify the minimum limit of the deadzone for the difference between the set reference power and curtailment power. |
Maximum power difference deadzone limit | pu | Specify the maximum limit of the deadzone for the difference between the set reference power and curtailment power. |
Minimum power difference saturation limit | pu | Specify the lower bound of the saturation for the difference between the set reference power and curtailment power. |
Maximum power difference saturation limit | pu | Specify the upper bound of the saturation for the difference between the set reference power and curtailment power. |
