¶ Overview
The Control tab contains two functions:
- Manual Setpoint — direct operator control of active power.
- NordPool Limiting — automated curtailment based on market price.
Note: The PPC applies the MIN rule across all external setpoints (TSO, User, Scheduling, NordPool). The lowest of these values becomes the Final Active SP for the plant.
¶ Manual Setpoint
Operators can directly set the active power output as a percentage of installed capacity.
Use this for ad-hoc curtailment or temporary operator overrides.
¶ NordPool Limiting
When enabled, plant output is automatically curtailed if the NordPool spot price drops below a defined threshold.
- NordPool Limit % — maximum output allowed when the price condition is met.
- NordPool Price €/MWh — threshold value; below this price, limiting is applied.
- Status panel — shows ON/OFF state and the last applied parameters.
Note: When active, NordPool limiting becomes one of the external setpoints. The PPC enforces the lowest setpoint across all active sources as the Final Active SP.
¶ Setpoint Summary
Bars show how each input (LitGrid, User, NordPool, Scheduling) contributes to the final limitation.
¶ Active Power Graph
The graph at the bottom of the Control page overlays real-time power with setpoint curves.
Use the legend to toggle curves and zoom into time windows. This helps confirm whether plant output follows the PPC-determined Final Active SP.
¶ Navigation to Other Tabs
From the Control page, operators can move to other limitation functions:
- 🗎 Scheduling → Configure daily/hourly curtailment (MWh/15 min).
- 🗎 MT Limiting → Apply per-transformer maximum output caps.
