New control technique for microgrid-connected PV systems

An international research group has applied for the first time integral backstepping control (IBC) as a control strategy for PV systems connected to microgrids. Through a series of simulations, the scientists found the new approach can provide better results than classic backstepping control (BC) and other techniques.

Weekend read: 100% solar offgrid, 100% on wheels

Jason and Kara are Canadian overlanders from the “Everlanders” channel on YouTube. Overlanding is self-reliant travel on the road, driving to remote places across international borders. pv magazine caught up with Jason between legs of their latest road trip.

PV cell technology trends

Ongoing innovation in PV cell technology will have major impacts as solar is deployed at a “multi-terawatt scale” over the next two decades, according to a global team of scientists.

Jaguar building large-scale storage system with second-life EV batteries

Jaguar Land Rover and Wykes Engineering are building a 2.5 MWh storage system with electric-vehicle batteries taken from Jaguar I-PACE cars. The large-scale system will store wind and solar at an undisclosed location in the United Kingdom.

Australia’s R&D spend continues to shrink despite global clean energy race intensifying

Australia continues to rank poorly for investment in science and research, spending just 1.68% of its GDP – well below the OECD average. This underinvestment is a growing problem for the clean energy industry, with fellow nations actively poaching innovations to capture future manufacturing markets.

Energy management system to combine residential PV with gravity storage

Researchers in Morocco have created a new energy management system that allows the combination of rooftop PV with gravity storage. The proposed system is reportedly able to perform smart energy distribution within a household while also lowering electricity costs.
