Large-scale multi-area economic/emission dispatch based on a new symbiotic organisms search algorithm

The performance of the proposed NSOS algorithm is tested in nine cases (on five systems with different characteristics comprising 6-unit, 10-unit, 40-unit, 120-unit and 130-unit), the majority of which analysing large-scale systems. The results obtained by using the NSOS algorithm show it performs better than the SOS algorithm or other algorithms reported in literature.
