Application of Tabu Search Algorithm to Security Constrained Economic Dispatch

This paper presents an algorithm for solving Security Constrained Economic Dispatch (SCED) problem through the application of Tabu Search (TS). The SCED problem is formulated with base case and contingency case line flow constraints, which are important for practical implementation. Two representative systems namely 66-bus and 191-bus Indian utility systems are taken for investigations. The SCED results obtained using TS are compared with those obtained using Genetic Algorithm (GA) and Evolutionary Programming (EP).
