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 of 3-machine 6-bus, IEEE 5-machine 14-bus, IEEE 6-machine 30-bus,
and 13- and 40-unit test systems both with transmission loss and without transmission
loss. These test cases show that SOS is able to converge on the global optima, successfully.
Moreover, results obtained from the proposed algorithm are compared through different
methods used in solving the ELD problem existing in the literature. According to these
results, SOS produces the best values among all methods.
