BayWa re and Ampt, in collaboration with the Fraunhofer Institute for Chemical Know-how (ICT), have developed an modern and technically difficult hybrid system that includes 690 kWp of rooftop and ground-mounted PV, a 2 MW wind turbine, and a ten MWh flow-battery power storage system.
German renewable power developer BayWa re and Ampt, a US-based DC optimizer producer, have introduced the deployment of a hybrid wind-solar-flow battery facility within the microgrid of the Fraunhofer ICT campus in Pfinztal, Germany.
The challenge, billed as the primary of its type in Europe, options three rooftop arrays and one new ground-mounted PV system, with a complete capability of 690 kWp. They’re related to the ability grid through an current 2 MW wind turbine as an alternative of their very own inverters. The challenge additionally incorporates a 10 MWh circulation battery power storage system.
Every of the completely different applied sciences have been built-in via a shared DC bus – generally known as DC-coupled structure – utilizing Ampt String Optimizers, a sort of DC/DC converter that performs most energy level monitoring (MPPT).
Ampt’s optimizers use particular person string MPPT to mitigate power losses attributable to shade from surrounding buildings on the Fraunhofer ICT campus. The optimizers are programmable and supply string-level knowledge, which boosts visibility of the system capabilities, in addition to operation and upkeep capabilities.
Andrea Grotzke, international director of power options at BayWa re, mentioned Ampt’s know-how “simplified a technically very advanced challenge.”
“The best way we’ve got added photo voltaic to the present wind power and battery storage system is exclusive, and in efficiently finishing this challenge we have been capable of additional enhance our personal experience and capabilities,” mentioned Grotzke.
In response to Levant Gun, the CEO of Ampt, combining rooftop and ground-mounted photo voltaic in seven completely different orientations and two module sizes in a single frequent microgrid with wind energy and batteries was a major problem.
“This challenge is a testomony to the capabilities of our industry-leading energy conversion know-how to simplify management of the varied programs unfold throughout a website,” Gun mentioned.
Fraunhofer ICT mentioned it’s going to use the system to assist its campus of greater than 100 laboratories, in addition to a number of pilot plans and three check facilities.
“It was vital for us so as to add photo voltaic to the microgrid that powers our campus, to carry further flexibility and guarantee increased utilization of our system,” mentioned Frank Henning, institute director of Fraunhofer ICT. “Sustainability performs a vital function for Fraunhofer ICT, and by combining some great benefits of wind, photo voltaic and storage, we’re ensured to fulfill our sustainability objectives and function in a accountable method.”
