The Power Flow Equations - Iowa State University

Relation between real power injections and angles. As promised in Section 7.0, let’s write 2 KCL equations at nodes 1 and 2 as a function of voltage variables at those nodes, using “Ohm’s Law for Real Power Flow.” It will be: Node 1: (19) Node 2: (20) Collecting terms with common angles in both (19) and (20), we get: (21) (22) Writing eqs. ................
