DECOUPLED SECURE ECONOMIC DISPATCH ALGORITHM FOR POWER SYSTEMS OPERATION Available to Purchase

This paper describes an algorithm which can be used to determine the optimal power flows of a network via the Dommel‐Tinney approach with or without the incorporation of security constraints; security constraints are properly handled via sensitivity analysis and least‐squares minimisation techniques. The algorithm can also determine the security enhancement of a network without taking the economics of operation into consideration. The refined second‐order loadflow method using rectangular coordinates is employed and the contingencies are determined by second‐order corrections on the base‐case; the computational aspects of this development are highlighted in the appropriate sections. The main emphasis of this paper is on numerical methods.
