Dear Ray Sir, Thank you for your reply. I have still two queries. (1) In matpower 4.1, the size of hessian obtained from ACOPF is 66*66. But shouldn't it be 72*72, as it has 30 voltage magnitudes, 30 voltage angles, 6 active power flow injections and 6 reactive power flow injections. (total size=30+30+6+6=72)? (2) Is there any equation for determining the size of Jacobian for ACOPF?
