Elephant Herd Optimization Algorithm for Optimal power flow model incorporating with PV and Wind

Abstract

In the paper, an enhanced optimal technique is proposed for solving the optimal power flow (OPF) issues with uncertainties. An enhanced technique is the EHO calculation, which is roused bythe crowding conduct of elephant gathering. Originally, the OPF is examinedwith the (N-R) Newton-Raphson (N-R) approach after that, the wind and PV based power scheduling is performed. For the wind and PV analysis, the output power is determined from the Weibull PDF and Lognormal PDF. Initially, the objective functionis defined and analyzed the voltage deviation, power loss and generation cost. For the OPF analysis, multi-objective functions are considered under the uncertainty period. The activities are decided for various reasons depending on the variable costs of building photovoltaic and wind farms, radiation, discharge costs, transmission disturbances and voltage stability. The suggested procedure is tested with the IEEE 57 bus system and analyzed the corresponding emission coefficients, generation cost coefficients and etc.
