The Path to Future‐Proof Photovoltaics in Europe: Current Status and Impact of Technological Innovation on Reliable and Bankable Photovoltaics

Advanced Energy and Sustainability Research, Volume 7, Issue 6, June 2026.
This article provides an overview of the current state of the art and future improvements in PV technology and explains how changes in the technology and design of individual PV components—at the module level, the balance‐of‐system (BOS) level, or the PV plant level—can affect the reliability, durability, and energy output of a PV system.

Coordinated DC Fault Ride‐Through Control for a Grid‐Forming Wind‐Storage System With VSC‐HVDC Integration Under Transmission Constraints

Engineering Reports, Volume 8, Issue 6, June 2026.
Due to complex wind farm conditions, a coordinated control system was designed. It manages DC power surges during AC faults by temporarily storing excess energy and regulating voltages. This strategy optimizes unbalanced power and enables effective fault recovery, resulting in minimal voltage fluctuations and superior performance.

Geomagnetically Induced Currents, Transformer Harmonics, and Reactive Power Impacts: Observed Response of a Single‐Phase Transformer in New Zealand

Space Weather, Volume 24, Issue 6, June 2026.
Abstract Geomagnetic storms represent a space weather hazard to power transmission networks due to the effects of induced geo‐electric fields within the conducting surface of the Earth. These drive electric currents in power transmission lines which can flow to ground through the neutral‐ground connections of transformers.
