PV-driven microgrid for hydrogen, cooling
The University of French Polynesia has built a PV-driven hydrogen generation unit that combines a hydrogen chain with a thermochemical unit. The latter is used to recover waste heat from the electrolyzer and fuel cell to enable deferred cooling production for air conditioning.
Collectively owned PV systems improve energy community performance
Researchers have looked into the impact of potential regulated charge exemptions on two types of energy communities in 39 European countries. They have found that communities with collectively owned PV systems achieve greater savings.
Israel temporarily waives 600 KWh energy storage permits due to war
The Israeli planning regulator says that some storage facilities will not need permit approvals over the next 18 months.
Israeli regulator approves regulatory framework for storage
Israel’s planning administration has approved the terms for deploying up to 16 MWh of storage facilities. The government said that due to the Gaza conflict, storage has become ever more important for emergencies.
Integrating sky images, global solar irradiance into solar forecasting algorithms
A research team in the United States has created a novel approach to integrate raw sky images and global solar irradiance measurements, solar nowcasting, and intra-hour forecasting. The methodology utilizes low-cost radiometric IR cameras instead of expensive ceilometers.
Hybrid PV-biogas microgrids for EV charging
An international research team has examined the potential use of hybrid microgrids that integrate PV and biogas for electric vehicle recharging in Karnataka, India. Their findings indicate that this combined approach offers economic and environmental benefits compared to separate biogas and PV systems.
First AI-based control method for vanadium redox flow batteries
Australian researchers are proposing a novel, learning-based H∞ control method to enhance the performance of vanadium redox flow batteries in DC microgrids.
What can Western utilities learn from emerging-market peers?
While electric companies in the Global North wrestle with how to keep the lights on as ever bigger solar and wind park capacities come online, developing-world utilities are experimenting with new ways of working and transforming the relationship between themselves and millions of new customers.
Weekend Read: Planning a Hamba-lution
As the global North ponders e-mobility dilemmas such as how to source sufficient materials to meet electric car demand, fresh evidence has emerged of how solar can decarbonize transport and farming in Africa.
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.
