End of load shedding ‘finally within reach,’ says South African president
South African President Cyril Ramaphosa says the country has overcome the worst of its power shortages due to tax incentives, investment, the expansion of rooftop solar capacity, and the construction of new transmission lines, despite additional recent power cuts by utility Eskom.
Optimizing photovoltaic grid integration through active power management
PV systems, surpassing minimum load demands in various regions, necessitate innovative grid integration measures. Active power management (APM), notably curtailment, emerges as a powerful solution here. By actively managing power peaks, PV systems can unlock new possibilities, contribute to grid stability, and enhance their overall value. The new IEA-PVPS Task 14 report encourages a shift in perspective, urging DSOs to explore the potential of APM instead of traditional grid expansion methods.
Australian energy modeler installs power-management tech at defense sites
Proa, an energy forecasting company, is rolling out its technology at solar farms at two national defense facilities in northern Australia, with positive implications for scheduling solar energy commitments with certainty.
The solar rebound effect in residential PV
The rebound effect consists of a reduction in expected gains from a more resource-efficient technology as a result of behavioral or systemic change. An international research team has investigated this phenomenon in the residential PV segment in Vietnam and has found that it could happen in any country where the policy supporting solar power is not fully and scientifically explained.
Sunrun solar-plus-storage powers the grid during peak demand
In partnership with utility Pacific Gas and Electric, the residential solar installer enrolled distributed batteries to serve the grid during times of peak demand.
Mauritania secures $289.5 million for solar projects, interconnection line
The authorities in Mauritania have obtained $289.5 million of financing for two solar projects, including a $272 million loan – the largest ever granted to the country by the African Development Bank – for a recently approved 225 kV electricity interconnection.
SolaX Power releases new residential batteries
China’s SolaX Power has developed two lines of integrated energy storage systems that reportedly support up to 200% PV oversizing. Their rated output power ranges from 3 kW to 15 kW.
Behavioral perspectives on adoption of residential PV systems
Scientists in China have used computer simulations to gain a better understanding of the factors that influence the adoption of residential PV.
Cloud fraction nowcasting method for PV applications
Researchers in China have developed a novel way to predict the cloud coverage of PV plants. The method uses geostationary satellite and recurrent-neural networks.
Smart grids could improve Saudi Arabia’s renewables potential
Saudi researchers say smart grids could have a minimal impact on the environment in Saudi Arabia, while supporting a technologically advanced power system compatible with end users.
