I’m afraid you’ll have to work out those derivations yourself (I don’t know
that I’ve actually ever done it). You may find the derivations in the MATPOWER
Tech Notes TN2, TN3 and TN4 to be helpful as patterns for doing the
derivations. You can find them here
<https://github.com/MATPOWER/matpower/tree/master/docs>.
