    This paper presents a method to compute maximal steady-state security regions based on the DC load flow model. The proposed method consists of three steps. First, an initial region (hyperbox) is obtained explicitly using an analytic method. A developed algorithem is then utilized to expand the upper and lower bounds of the initial region in as many dimensions as possible. The algorithm is based on... View full abstract»

    Traditionally, electric utilities have forecast the demand for their product and planned a supply system to satisfy the market. Rather than treating the forecast demand as a given, Florida Power & Light Company (FPL), has established a marketing planning function to alter future demand through direct involvement in the marketplace. The crucial element in management's evaluation of opportunities to... View full abstract»

    A model at harmonic frequencies is developed for a static VAR compensator. The model consists of a harmonic voltage source in series with a variable source admittance. The model is shown to be useful in predicting resonance problems using digital simulation. Equations are also developed which show that a static VAR compensator can be described by a system of linear differential equations with peri... View full abstract»

    This paper describes a load management program successfully implemented in Sweden. There is today an excess supply of electric energy in Sweden mainly due to the fast developement of nuclear power. This has resulted in a temporary situation with excess low-cost hydro and nuclear power. To take advantage of this situation, a complete load management system based on a personal computer was designed ... View full abstract»

    Strategic switching can be achieved by a current injection scheme which simulates the change in topology. The injected currents are applied to the terminals of the elements of a socalled base network corresponding to those actually switched. This requires that the base network must contain all elements in the "in" state. The injected currents to be used as a compensation in the commonly employed s... View full abstract»
