Iterated Local Search Solution for the Non-convex Economic Dispatch Problem

Nabil Nahas, Mohammed Abouheaf, Adel Sharaf, and Wail Gueaieb
Abstract—The objective of the Economic Dispatch problem is to allocate the total power generation to the generating units to meet a given total active-load demand. This problem cannot be solved using the traditional analytical approaches, due to the high non-convexity of the objective cost functions. This work introduces an iterated local search algorithm that employs the great deluge search method to solve the non-convex Economic Dispatch problem. This algorithm has demonstrated efficiency in solving various NP-hard problems but has never been applied to solve the Economic Dispatch problems. The performance of the proposed algorithm is compared to those of other search algorithms using standard benchmarks. The simulation results verified the superior performance of the proposed algorithm compared to the other approaches.

Index Terms—Economic dispatch, valve-point loading effects, non-convex optimization, great deluge algorithm.
