GLOBAL MAXIMUM POWER POINT TRACKING EXTRACTION IN PHOTOVOLTAIC SYSTEMS USING PARTICLE SWARM OPTIMIZATION UNDER PARTIAL SHADING CONDITIONS

In recent years, photovoltaic (PV) energy systems have been largely expanded, thanks to advances in technology, the gradual decrease whether in installation or maintenance costs. According to the literature, Numerous maximum power point tracking (MPPT) techniques have been proposed to enable PV systems to operate at th...

Robust T-S Fuzzy Control Design for Variable-Speed Wind Energy Conversion Systems Using Linear Matrix Inequalities

This paper proposes a robust state feedback control strategy for variable speed wind energy conversion systems (WECS) within the Takagi-Sugeno fuzzy (TSF) modeling framework. A T-S fuzzy representation is used to approximate the nonlinear aerodynamic behavior of the wind turbine. This representation enables to design a...

DFT analysis of physical properties and solid-state hydrogen storage potential of Sodium-Based Double Perovskites Na 2 XH 6 (X = V, Cr and Co)

This study investigates novel hydrogen storage materials Na 2 XH 6 (X = V, Cr and Co) using first-principles density functional theory (DFT) within the GGA-PBE approximation, as implemented in the CASTEP code. The structural, electronic, mechanical, optical and thermal properties are systematically analyzed. Grav...
