Reference / Grid limit ceiling

Model option

Run to the ceiling

The inverters run to the ceiling, and the AC losses are taken there

Inputs used: Grid power limitation, Grid limitation at, Grid limitation: account as separate loss, Grid limit ceiling

Method

On a timestep where the array could deliver more, each inverter brings its output down to the ceiling of the Grid power limitation step (1). The AC losses after the inverters are taken on that output.

The AC side from the inverters to the grid, and where each loss row is counted

The math

Pinv=Pmax(1)P_{inv} = P_{max} \tag{1}

where

Symbol Meaning Unit
PinvP_{inv} the output of one inverter. On a timestep the limit binds W
PmaxP_{max} the AC ceiling of one inverter. Set by the Grid power limitation step W
