Single-objective optimal power flow for electric power systems based on crow search algorithm

摘要

This paper presents the application of a recent meta-heuristic optimization technique named a crow search algorithm (CSA) in solving the problem of an optimal powerflow (OPF) for electric power systems. Various constrained objective functions, total fuelcost, active power loss and pollutant emission are proposed. The generators’ output powers, generators’ terminal voltages, transmission lines’ taps and the shunt capacitors’ reactive powers are considered as variables to be designed. The proposed methodology basedon the CSA is applied on an IEEE 30-bus system and IEEE 118-bus system. The obtainedresults via the CSA are compared to others and they ensure the superiority of the CSA insolving the OPF problem in electric power systems.
