Single Diode Solar Cells—Improved Model and Exact Current–Voltage Analytical Solution Based on Lambert’s W Function

Sensors, 2022
There are three standard equivalent circuit models of solar cells in the literature—single-diode, double-diode, and triple-diode models. In this paper, first, a modified version of the single diode model, called the Improved Single Diode Model (ISDM), is

Predictability of Power Grid Frequency [PDF]

IEEE Access, 2020
The power grid frequency is the central observable in power system control, as it measures the balance of electrical supply and demand. A reliable frequency forecast can facilitate rapid control actions and may thus greatly improve power system stability.

Influence of the DLC Passivation Conductivity on the Performance of Silicon High-Power Diodes Over an Extended Temperature Range

IEEE Journal of the Electron Devices Society, 2021
The diamond-like carbon (DLC) is important for passivation of junction termination in high power devices due to its excellent electrical, mechanical, and thermal properties. While the role of conductivity and polarization of the DLC layer on the blocking

Reduction in Voltage Harmonics of Parallel Inverters Based on Robust Droop Controller in Islanded Microgrid

Mathematics, 2022
In this article, a distributed control scheme to compensate for voltage harmonics in islanded microgrids is presented, where each distributed generation (DG) source has a primary control level and a secondary control level. In addition to the voltage and
