Energy Management Systems

The power electronics company is offering a product which can work on and off the grid and enables the charging of dead batteries using a rooftop solar array.

With a flurry of recent announcements, the newly-launched power division of the electronics giant plans to drive hydrogen mobility in Germany and enter the commercial and industrial power market in the US.

A small-area trial of artificial intelligence and blockchain-based energy trading software demonstrated big improvements across all renewable energy performance metrics. The port authority now wants the system across all its premises.

As some parts of Australia’s distribution networks threaten to black out under the flow of rooftop solar exports, ARENA announces funding for a trial that will enable flexible exports in line with what the networks can bear. Smart software is the answer.

Victory in the economic realm (increasingly the case with solar, solar-plus-storage and wind) is no guarantee of market victory if the regulations are stacked against renewables.

Scientists in Switzerland say power-to-hydrogen is particularly promising for coupling electricity and heating and offsetting seasonal variation in renewables generation in sector-coupled energy networks. Their analysis indicated the technology may be especially useful in areas with a high ratio of seasonal thermal-to-electric demand.

Researchers say the technology could help drive clean energy deployment in countries with limited grids or in isolated, coal-based energy systems. According to their model, Kosovo could see a strong increase in wind and PV capacity if power-to-heat is coupled with thermal energy storage for fixed-capacity district heating.

In-country analyst the AECEA has speculated the authorities could be ready to wipe the slate clean for the start of the nation’s 14th five-year plan on January 1. The analyst has raised its solar expectations for the year but noted the sky-high price of polysilicon remains a concern for developers.

The annual EU PVSEC conference got under way virtually this morning via an online platform since the planned event in Lisbon could not go ahead due to the Covid-19 pandemic. Opening presentations revealed an air of optimism in the PV industry, amid expectations of a rapidly rising share in the energy mix, growing conversion efficiencies, advancing technology pathways and innovative solutions to the problem of integrating high levels of PV into electricity grids.

Around 4.2 MWh of energy storage capacity will be connected to a solar and diesel micro-grid on Rarotonga, the largest of the islands in the South Pacific nation. Three 40-foot containers with a total power output of 4.8 MVA will be used as a power reserve and for grid support by utility Te Aponga Uira.
