Grids & Integration

Scientists in Mexico have conceived a new solar module cooling tech that can reportedly improve PV power generation by up to 2%. The system uses nanofluids embedded in an aluminum single-channel attached to the back of the panel.

A new report by the International Energy Agency’s Photovoltaics Power Systems Programme (IEA-PVPS) says that existing PV systems have the technical capabilities to provide various frequency-related grid services.

Scientists used a year’s worth of data from East China to analyze what weather conditions affect abnormal, high, and low PV output days. They also constructed a simple extreme output prediction model and examined the atmospheric circulation anomalies corresponding to extreme output events.

The Israeli Ministry of Energy and Infrastructure has presented three scenarios for its 2050 green goals, changing in accordance with developments in solar, hydrogen, and nuclear power production. In the most solar-focused scenario, the country would have a PV capacity of 108 GW.

Finland-based Wärtsilä Energy has upgraded its GEMS digital energy platform to transform the way GWh-scale battery energy storage projects (BESS) are managed in Australia.

Researchers have simulated the addition of PV plants and waste-to-energy systems in the Iraqi Al-Gharab region, that suffers from power cuts, and have identified the optimal size and locations for these hybrid plants, with the LCOE dropping by 7.7%.

A European research team has proposed a new methodology for optimal design of hybrid wind-solar power plants. Their approach is based on 1-minute resolution data, which the scientists said provide much more accurate information about potential curtailment and clipping losses compared to 1-hour resolution data.

Conceived by an international research team, the new bidding strategy applies to the day-after and the intraday markets. It uses a technique that transforms results from probabilistic models into actual scenarios. Their method showed its ability to yield increased revenues and reduced imbalance.

Using a range of machine-learning techniques, a group of scientists found that PV systems can significantly increase the value of a property in the United Kingdom. The analysis was based on property data from Zoopla, one of the leading providers of UK property listings, and price paid data sourced from the government’s Land Registry from 2012-2018.

The Romanian Energy Regulatory Authority (ANRE) has adopted several changes to grid connection processes, including the implementation of an auction-based grid connection mechanism for plants above 5 MW from 2026 onwards.
