Abstract: The penetration of solar photovoltaic (PV) systems in residential areas contributes to the generation and usage of renewable energy. Despite its advantages, the PV system also creates problems caused by the intermittency of renewable energy. As suggested by researchers, such problems deteriorate the applicability of the PV system and have to be resolved by employing a battery energy s...

Numerical simulation has become indispensable in advancing cost-effective process optimization and control of flow batteries. We propose an enhanced version the physics-constrained deep neural network (PCDNN) approach (He et al., 2022) to provide high-accuracy voltage predictions vanadium redox batteries (VRFBs). The purpose PCDNN is enforce physics-based zero-dimensional (0D) VRFB model a assu...

For a PEMFC to work better, adding baffles flow channel can improve reactant transfer. As result, the starts by developing 3-D numerical model for vanadium redox battery (VRFB) using COMSOL Multiphysic Simulation Software. By incorporating into serpentine channel, it is possible simulate changes in ion concentration and terminal voltage. The findings indicate that efficiency will be impacted ba...

The preparation of highly pure vanadyl sulfate from sulfate solutions containing impurities of iron and aluminumwas investigated by solvent extraction with 2-ethylhexyl phosphoric acid mono-2-ethylhexyl ester (EHEHPA) and tri-n-butyl phosphate (TBP) as the phase modifier. The extraction and stripping conditions of vanadium (IV) and its separation from iron and aluminum were optimized. Under the...
