Even though electric power networks are composed of components which are (or can be approxi mated... more Even though electric power networks are composed of components which are (or can be approxi mated to be) linear, electric power flow, real and reactive, is a nonlinear quantity. The calculation of load flow in a network is the solution to a set of nonlinear equations. The purpose of this note is to describe how network load flows may be calculated. This is only an elementary treatment of this problem: there is still quite a bit of activity in the professional literature concerning load flow algorithms. The reason for this is that electric utility networks are often quite large, having thousands of buses, so that the amount of computational effort required for a solution is substantial. A lot of effort goes into doing the calculation efficiently. This discussion, and the little computer program at the end of this note, uses the crudest possible algorithm for this purpose. However, for the relatively simple problems we will be doing, it should work just fine.
