BayWa r.e. and Ampt have deployed a mixture of wind and photo voltaic technology along with battery storage inside the microgrid on the Fraunhofer Institute for Chemical Expertise (ICT) campus in Pfinztal, Germany.
BayWa r.e. put in three rooftop arrays and one ground-mounted system with a complete capability of 690 kWp to increase onsite power utilization. The techniques are linked to the ability grid with out their very own inverters, however as an alternative by means of an present 2 MW wind turbine. A ten MWh circulate BESS is a part of the system as properly.
Leveraging Ampt String Optimizers, every of the completely different applied sciences was built-in by means of a shared DC bus, says the corporate, including that this manner, technology variability throughout the PV techniques will be managed and the completely different techniques united at a excessive and stuck voltage.
Ampt String Optimizers are DC/DC converters that carry out most energy level monitoring (MPPT) and recuperate power losses as a consequence of voltage and know-how variations, in keeping with BayWa r.e. By way of particular person string MPPT, Ampt optimizers mitigate the power losses brought on by shade from surrounding buildings on the Fraunhofer ICT campus. The optimizers are programmable and supply string-level information, enhancing visibility of the system features in addition to operation and upkeep capabilities.
“We’re delighted to carry this milestone mission to life. Ampt’s know-how simplified a technically very advanced mission,” says BayWa r.e.’s Andrea Grotzke. “The way in which we have now added photo voltaic to the prevailing wind power and battery storage system is exclusive, and in efficiently finishing this mission we have been in a position to additional enhance our personal experience and capabilities. We’re happy with the results of this progressive energy answer symbiosis and our potential to satisfy our buyer’s particular person necessities.”
