Abstract

Symbiotic Organisms Search (SOS) is a brand new and effective metaheuristic optimization algorithm. This paper proposes the SOS algorithm to solve the Economic Load Dispatch (ELD) problem with valve-point effect, which is one of the essential optimization problems in modern power systems. The proposed algorithm is tested on five different test cases consisting 3-machines 6-bus, IEEE 5-machines 14-bus, IEEE 6-machines 30-bus, 13 and 40 unit test systems including both transmission loss and without transmission loss. These test cases show that SOS is able to converge to the global optima successfully. Moreover results obtained from proposed algorithm are compared through different methods used in solving the ELD problem existing in the literature. According to these results, SOS produces better values than all.
