Hybrid Big Bang-Big Crunch Algorithm for solving non-convex Economic Load Dispatch problems

Abstract

Accurate and realistic Economic Load Dispatch (ELD) is one of the most important issues in power systems. In real conditions, ELD is limited to the different non-equal constraints that make ELD a non-convex and non-smooth problem. This makes it difficult to find a global optimized solution, even with the aid of classic mathematical methods. In this paper, a novel procedure is presented for solving ELD problems, which uses Hybrid Big Bang-Big Crunch Algorithm (HBB-BC) as an optimization tool. This algorithm has appropriate speed and accuracy compared with the most regular optimizing methods. The proposed algorithm is applied on an IEEE 30-bus test system. Simulation results demonstrate the algorithm's capability for successful optimization of ELD problem.
