This paper presents the minimization of the voltage deviation and power loss, which is related to ORPD in unbalanced conditions. Moreover, a hybridization of two techniques (i.e.,) PSO and WOA termed Hybrid (PSO-WOA) algorithm is developed in this paper. Here, this proposed technique works on the control variables namely transformer tap settings, voltage, and load reactance that are diverse to attain optimum outcomes. The complete experimentation is performed on two IEEE bus systems, such as the IEEE 39 and 14 bus systems. The simulation outcomes of the proposed PSO-WOA technique are analyzed with conventional techniques to assure the proposed technique.
