Multi-Objective Spotted Hyena Optimization-Based Control of Grid-Tied PV System

Abstract

This article describes the multi-objective spotted hyena optimization (MOSHO) based control of a three-phase three-wire grid-tied dual-stage PV system. The MOSHO delivers an optimized step size $\left(\mathit{\delta }\right)$ for the incremental conductance (InC) based maximum power point tracking (MPPT) algorithm, as well as optimizes the PI controller gains for DC bus voltage $\left({\mathbf{V}}_{\mathbf{d}c}\right)$ regulation. The $\mathit{\delta }$ optimized MPPT facilitates the faster and more accurate tracking of maximum power point with fewer fluctuations at steady-state. The MOSHO optimized PI controller regulates the ${\text{V}}_{\text{dc}}$ and delivers better stability with reduced ${\text{V}}_{\text{dc}}$ variations in DC bus voltage during steady-state and dynamic states, i.e. irradiation variation, abnormal and unbalanced grid voltage. The optimized DC bus generates an accurate loss component of current, which further enhances the voltage source converter (VSC) performance in terms of precise reference currents generation and power quality improvement. The proposed system performs satisfactorily in a MATLAB simulation environment as per IEEE519 standards.
