1. A method of generating a connectivity model of a power distribution network, said method comprising one or more steps for: inserting a power directing element in the connectivity model, the power directing element having a first node coupled to a first branch of the connectivity model and a second node coupled to a second branch of the connectivity model; assigning an actual phase value to the power directing element and to the first node and the second node, the actual phase value for the first node and the second node corresponding to, respectively, the first branch and the second branch; and generating the connectivity model with the actual phase values.
