A paragraph should probably be added to explain the bounds of active power transit in the HVDC line, and the formula for the line losses.

- $P_{controller} = P_0 + k~(\theta_1 - \theta_2)$
- $P_{noncontroller} = (1 - loss_{noncontroller}) * ((1 - loss_{controller}) * (P_0 + k~(\theta_1 - \theta_2) - P_{LineLoss}))$

In both regulation modes, the power transits are impacted by losses of the converter stations. In addition, Joule effect (due to resistance in cable) implies line loss in the HVDC line.

Thank you for your review, I agree with all your precisions and modified the doc.

- In **AC emulation** mode, the active power flow between both stations is given by: $P = P_0 + k~(\theta_1 - \theta_2)$
with $\theta_1$ and $\theta_2$ being the voltage angles at the bus connection for each converter station, and $P_0$ and $k$ being fixed parameters for the HVDC line.
If $P$ is positive, the converter station 1 is controller, else it is converter station 2. For example, if station 1 is controller, the

@SylvestreSakti I have changed the sentence because I think it was wrong. Maybe just check my rewording "If $P$ is positive, the converter station 1 is controller, else it is converter station 2. For example, if station 1 is controller, the
active power flow at each station is given by:..."

Thank you Anne, indeed it was wrong, I should have named the angles theta_{controller} and theta_{noncontroller} but I think your rewording seems more clear.
