About the ramp rate limiter

To avoid rapid changes in the active and reactive power output, the Ramp rate limiter feature allows the power generating system to follow a defined gradient to increase or decrease the power output after a command is sent by the grid operator or energy trader.

The ramp rate limiter is available for active and reactive power control. The functions are described below.

Ramp rate limiter for active power

Under Power control > Active power, you can configure the ramp rate limiter for active power individually for:

• Grid operator commands

• Energy trader commands (RPC license)

In each case, you can choose between two modes:

Ramp rate limiter for reactive power

For reactive power control, the ramp rate limiter applies to ramp-up and ramp-down.

Examples

	Grid operator command	Output signal
