Online correction dispatch algorithm for dynamic security

The paper considers a novel way of scheduling generations and loads for enhancing stability of overall power systems. Based on a so-called structure-preserving model, an algorithm is proposed for correcting the dynamically insecure system. The algorithm proposed aims at online computer applications. In the event of an emergency, the percentage load to be shed and the busbars which are affected would aid the system operator, as is illustrated by the application of the algorithm on a sample 5-busbar power system. The algorithm aims at minimising deviations from an economically optimum operating point which is the usual choice for alternative operation of power systems.
