Dear Dr Zimmerman,
In an ACOPF, the Matpower seems to set Voltage_angle(bus1) = 0 . However, this is not required - although it is not a mistake. Is it compulsory to set this voltage_angle zero? Thank you ________________________________ From: Ray Zimmerman <[email protected]> To: MATPOWER discussion forum <[email protected]> Sent: Wednesday, May 1, 2013 5:26 PM Subject: Re: P_V curve MATPOWER does not compute the L-index directly. However, you may find the contributed (i.e. unsupported) continuation power flow code useful for finding PV curves.
