Abstract:

 

This paper proposes an improved firefly (FF) algorithm   with multiple workers for solving the unit commitment (UC) problem of power   systems. The UC problem is a combinatorial optimization problem that can be   posed as minimizing a quadratic objective function under system and unit   constraints. Nowadays, highly developed computer systems are available in   plenty, and proper utilization of these systems will reduce the time and   complexity of combinatorial optimization problems with large numbers of   generating units. Here, multiple workers are assigned to solve a UC problem   as well as the subproblem, namely economic dispatch (ED) in distributed   memory models. The proposed method incorporates a group search in a FF   algorithm and thereby a global search is attained through the local search   performed by the individual workers, which fine tune the search space in   achieving the final solution. The execution time taken by the processor and   the solution obtained with respect to the number of processors in a cluster   are thoroughly discussed for different test systems. The methodology is   validated on a 100 unit system, an IEEE 118 bus system, and a practical   Taiwan 38 bus power system and the results are compared with the available   literature.
