Abstract :
The authors address the problem of remedial-action computations for the purpose of alleviating overloads, abnormal voltages, etc. The method is based on a linear programming (LP) approach. Applications for voltage/reactive-power control, discrete capacitor/reactor switching, load transfer, and interchange control are considered. The method is optionally based on a DC or AC network model. It utilizes a number of innovations to yield an efficient computational procedure. The major innovations are: a procedure for determining coherent constraints which results in a fast identification of active constraints, fast linearization procedures for active constraints, procedures to define the region of validity of the linearized model, and a fast sparsity-coded LP algorithm. The performance of the method for large power systems is evaluated
