An improved standalone photovoltaic system with hybrid dual integral sliding mode and model predictive control for MPPT

open access: yesIET Renewable Power Generation, Volume 19, Issue 1, January/December 2025.
Fig. 1(a) depicts the advanced standalone PV structure in which a high gain multilevel boost converter works as a concussion between the PV module and the load. Abstract In this research paper, a double diode model‐based photovoltaic (PV) system with a proposed hybrid dual integral sliding mode control (DISMC) and model predictive control (MPC) based ...

COLLOCATED SIBC-FDTD METHOD FOR COATED CONDUCTORS AT OBLIQUE INCIDENCE

open access: yesProgress In Electromagnetics Research M, 2013
A collocated surface impedance boundary condition (SIBC) { flnite difierence time domain (FDTD) method is developed for conductors coated with lossy dielectric coatings at oblique incidence. The method is based on the collocated electric and magnetic fleld components on the planar interface between two media, and rational approximation for tangent ...

Face Centered Anisotropic Surface Impedance Boundary Conditions in FDTD : Improved performance of staircased mesh for shielding problems [PDF]

open access: yes, 2017
We present a new face centered approach to the collocation of the fields for the application of a surface impedance boundary condition (SIBC). This approach deals with the ambiguities in the surface normal that arise at the edges on stair-cased surfaces..

Quantifying Soil Loss in the Brazilian Savanna Ecosystem: Current Rates and Anticipated Impact of Climate Changes

open access: yesLand Degradation &Development, Volume 35, Issue 18, Page 5786-5803, December 2024.
ABSTRACT The Brazilian Savanna (Cerrado) is the second‐largest South American biome that corresponds to almost two‐third of the national agricultural production. Extensive agricultural‐driven land‐use changes have significantly altered the landscape, causing increased soil erosion. Furthermore, projections of climate change effects on the Cerrado raise
