Wind Farm (DFIG Phasor Model) - Negative active power;

Hi in the DFIG wind turbine phasor example ; power_wind_dfig ;

the measurements block uses a negative gain for active and reactive power.

This means the original active power into the grid is negative, meaning the wind turbine

is abosrbing power from the grid. But this is diffent from the explanation in the documentation ; https://www.mathworks.com/help/physmod/sps/ug/wind-farm-dfig-phasor-model.html

[ Simulation 1. Turbine response to a change in wind speed ].

My question is, why is the active power sign negative before the conversion

in the measurements block and how can I change it to positive.
