Grids & Integration

The 185 MW / 370 MWh Koorangie battery energy storage project in Victoria has reached a major milestone with developer Edify Energy confirming the system has successfully exported power to the grid for the first time.

A Chinese research group has created a novel method to calculate city-scale rooftop PV potential not only based on roof areas but also including installation parameters and economic feasibility. The novel methodology was demonstrated in Nanjing, east China, and was found to be superior to conventional methods when it comes to estimating planned capacity.

Researchers recommended that transmission system operators consider adopting grid-forming battery energy storage systems system-wide to improve grid stability and to maximize system hosting capacity for solar and wind generation.

Utility-scale solar is set to crank up the voltage, preparing to shift from 1.5 kV to 2 kV on the DC side. It is a move that could redefine PV system design and slash costs, but it won’t happen globally due to vastly different regulations as voltages rise, reports Tristan Rayner.

A German research team has investigated the feasibility of a large-scale PV-powered seawater reverse osmosis desalination plant in Jordan and has found that keeping the concentrate flow constant is the most appropriate desalination operating mode.

Only a day before cutting ties with the Russian power grid, Lithuania announced the launch of a major energy storage procurement exercise.

The Fraunhofer ISE has designed a novel method for assessing the potential of low-temperature heat sources for large-scale heat pumps. The five-step process was tested on the German city of Fellbach, enabling the identification of heat sources with LCOH lower than €0.1/kWh.

France’s Cour des Comptes has issued a warning about rising nuclear energy costs. It is urging state-owned utility EDF to reduce its financial risks in international projects.

New research from Sweden has shown that building global super grids across different continents could not necessarily result in increased investments in solar power. The scientists outlined the One Sun One World One Grid (OSOWOG) concept, which advocates the development of a global super grid covering 18 time zones.

Scientists in Spain have used genetic algorithms to optimize a feedforward artificial neural network for the prediction of energy generation of PV systems. Genetic algorithms use “parents” and “offspring” solutions to achieve better results in subsequent generations.”
