Separated reference values for the active power limitation
The total AC power that the grid management service settings refer to is the sum of the outputs of PV, hybrid and battery inverters. Without any further configuration, external setpoints for active power limitation of direct sellers or grid providers are given as a percentage of the total AC power. If the active power limitation is to refer to other reference values, configurations must be made in the parameters at the system level.
While the parameters can be used independently, they are recommended for direct sellers and grid providers due to differing setpoint priorities: the grid operator’s setpoints take precedence over those of the direct seller.
