Algorithm for online coefficient correction artificial neural network in MPPT controllers for solar batteries.

Trudy Odesskogo Politehničeskogo Universiteta, 2023
The main element of solar power plants is usually a power cascade (DC/DC converter, inverter). Converters in such generation systems should have high efficiency (at least 90%), high output signal quality and ensure operation of the power plant with ...

Mechanism of Quasi‐Power‐Frequency Resonant Overvoltage Triggered by Multiple Lightning Strikes in High‐Voltage Alternating Current Systems Equipped With Shunt Reactor

High Voltage, EarlyView.
ABSTRACT This paper investigates the generation mechanism of quasi‐power‐frequency resonant overvoltage triggered by multiple lightning strikes in high‐voltage alternating current (HVAC) systems equipped with shunt reactors. Based on field measurements from a 500 kV AC system, equivalent and simplified circuit models have been established to analyse ...

Transition Metal Dichalcogenide Multijunction Solar Cells Toward the Multicolor Limit

Solar RRL, Volume 10, Issue 13, 15 July 2026.
A thermodynamic design framework reveals how transfer‐printable TMD multijunction solar cells approach the multicolor limit. Within the 1.0–2.1 eV TMD bandgap window, a five‐junction ladder nears the efficiency plateau, while radiative efficiency, luminescent coupling, excitonic absorption, and bottom‐cell stability set the practical headroom for van ...
