AC Power Flow Model

AC power flow model is a model used in electrical engineering to analyze power grids. It provides a nonlinear system which describes the energy flow through each transmission line. Due to nonlinearity, in many cases the analysis of large network via AC power flow model is not feasible, and a linear (but less accurate) DC power flow model is used instead. Both of those models are very crude approximations to reality.

Famous quotes containing the words model, flow and/or power:

    She represents the unavowed aspiration of the male human being, his potential infidelity—and infidelity of a very special kind, which would lead him to the opposite of his wife, to the “woman of wax” whom he could model at will, make and unmake in any way he wished, even unto death.
    Marguerite Duras (b. 1914)

    The method of painting is the natural growth out of a need. I want to express my feelings rather than illustrate them. Technique is just a means of arriving at a statement.... I can control the flow of paint: there is no accident, just as there is no beginning and no end.
    Jackson Pollock (1912–1956)

    No punishment has ever possessed enough power of deterrence to prevent the commission of crimes. On the contrary, whatever the punishment, once a specific crime has appeared for the first time, its reappearance is more likely than its initial emergence could ever have been.
    Hannah Arendt (1906–1975)
