Major technical issues with increased PV penetration on the existing electrical grid [PDF]
In the past decade, the installation of rooftop PV (Photovoltaic) systems has substantially increased in many countries. This increase is anticipated due to government incentives like RECs (Renewable Energy Certificates) and feed-in tariff, to ...

Self-Commissioning of Inverter Nonlinear Effects in AC Drives [PDF]
The paper presents a novel technique for an accurate identification of the inverter nonlinear effects, such as the dead-time and on-state voltage drops. The proposed technique is very simple and it is based only on a current control scheme.

A Universal van der Waals Tunneling Injector for Monolayer CMOS
A universal van der Waals injector unlocks polarity‐flexible tunneling contacts for monolayer CMOS. SnSe2, an intrinsically degenerate 2D semiconductor, establishes polarity‐specific band alignments with both WSe2 and MoS2 channels, enabling steep switching, high on/off ratios, and a unified route to low‐power 2D logic.

Grid‐forming inverter control design for PV sources considering DC‐link dynamics
A grid‐forming inverter in an inverter‐dominated grid should operate as a dispatchable voltage source, which is difficult to achieve when the inverter is interfaced with nonlinear dc sources such as photovoltaic (PV) arrays.

When a grid-forming (GFM) inverter is connected to a low- or medium-voltage weak power grid, the line impedance with resistive and inductive characteristics will cause power coupling.

Defect‐Templated Phase Engineering in Atomically Thin Metals
Graphene defects are transformed from passive imperfections into programmable templates for phase‐selective growth of atomically thin silver. Plasma‐generated boundary defects favor Ag(1), whereas sp3‐rich zero‐layer graphene promotes Ag(2). This defect‐directed intercalation links local graphene chemistry to crystalline phase, electronic structure ...

A simple estimation method of grid‐forming inverter inertia based on rate of change of frequency
Inertia is the core index of the estimation of power system frequency stability; a simple estimation method of grid‐forming inverter inertia based on the rate of change of frequency (RoCoF) is proposed in this paper.

The transition to renewable generation is replacing synchronous generators with inverter-based resources. This lowers system inertia and shifts the task of maintaining grid stability from rotating mass onto the control of the inverters themselves.

Control of a Grid-Forming Inverter Based on Sliding-Mode and Mixed H-2/H-infinity Control
A grid-forming inverter (GFI) is an important component for operation of an islanded microgrid. Its purpose, similar to a conventional slack bus generator, is to build up a reference voltage for other distributed generating units in the microgrid ...
