How to choose the channel of PCC to see active power in PSS/E
Excuse me,How to choose the channel of PCC to see active power and reactive power in PSS/E?

For wind machine, you can use machine PELEC and QELEC.
e.g. 302 is the bus the wind machine is connected to. psspy.machinearraychannel([-1,2,302],r"""1""",r"""Inv1P""") psspy.machinearraychannel([-1,3,302],r"""1""",r"""Inv1Q""")
For PPC or point of connection, you should add a dummy branch with zero impedance and measure the follow of p and q in the branch.
e.g. 102 and 102 is starting and ending of dummy branch psspy.branchpandqchannel([-1,-1,-1,101,102],r"""1""",[r"""POCP""",r"""POCQ"""])
What kind of equipment and dynamic model are you refering to?
thanks for your reply.I want to know how much active and reactive power the wind farm provides. Later I found out that I can see it by selecting the branch from the PSS / E internal channel.
