The main idea of this paper is to illustrate the interaction<lb>between various kinds of power system operational limits and<lb>corrective actions. In particular, the paper focuses on the interplay<lb>between line flow limits and active generation redispatch as the<lb>corrective action. The proposed methodology handles a wide range<lb>of flow limits by(More)
We study a thyristor controlled reactor circuit used for static VAR control of utility electric power systems. The circuit exhibits switching times which jump or bifurcate as fold or transcritical bifurcations. We study the nonlinear dynamics of the circuit using a Poincare map and demonstrate that the Poincarb map has discontinuities and is not invertible.(More)

This paper presents a vision of an efficient minimal role for an independent system operator (ISO) in a competitive market for electric power. The ISO framework could be achieved during the final stages of the transition to the deregulated environment. The chief responsibility of the ISO will be to maintain system reliability at all times. To achieve this(More)
This paper discusses the merits of an analytical method for determining the location and amount of series compensation to increase the steady state power transfer capability in the power system based primarily on cascading line overload considerations. Steady state transmission limits define the boundaries of a power system operating point. This paper(More)
The origin and quantum status of Fractional Charge in polyacetylne and field theory are reviewed, along with reminiscences of collaboration with John Bell on the subject. [ Invited Lecture at the International Conference ”Quantum (Un)speakables” in honour of John Bell, held at Vienna, November 10-14 , 2000. ]
The spatial variation in electricity spot prices in competitive markets is complex and counter-intuitive, and qualitatively different from other commodity markets. Even when transmission is only congested between two locations, it can result in price variations all over the system. In theory, market participants could use futures markets to eliminate the(More)
