Wind integrated multi area economic dispatch using backtracking search algorithm

This paper presents a solution of multi area economic dispatch (MAED) problem with wind integration using backtracking search algorithm (BSA), a novel optimization technique. BSA is a stochastic search algorithm with only one control parameter and mutation and crossover operators for exploration and exploitation of the search space for problem under consideration. It can easily take care of various complex operating constraints, which is difficult to solve using any mathematical approaches. To show its efficiency, BSA algorithm is applied to two different categories of MAED problems. Category I has a two area network having 40 and 140 power generating units with valve point loading effects (VPL), ramp rate limits (RRL) and prohibited operating zones (POZ) and category II presents simulation study of MAED problem with wind integration. The outcome of simulation results in terms of operating cost are compared with other recently published relevant approaches and are found to be better.
