Fraunhofer Institute for Industrial Mathematics (Fraunhofer ITWM) has linked an energy community to a channel near Amsterdam to the day-light and Dutch imbalance markets, which reduces energy costs.
Researchers at Fraunhofer ITWM has developed a solution that allows owners of solar systems and battery systems to participate in different energy markets.
The Fraunhofer team said that the solution makes the real-time prognosis of consumption and local generation possible, as well as price optimization, so that the user can buy and sell electricity at the best possible prices on the day-light market.
It was used in the Energy Community Schoonhip, an association of 30 floating houses with tanning systems, heat pumps and battery storage on a channel north of Amsterdam. Since January, the community has been connected to the Dutch energy and flexibility markets through the solution.
On the daily text market, where energy prices are negotiated a day in advance, the community can now benefit from dynamic electricity prices via Fraunhofer ITWM’s price optimization software, which is designed to take advantage of price fluctuations. The Fraunhofer team said that this is made possible by the sufficient flexibility and storage of the community of its energy system.
The community also participates in the Dutch imbalance market, where prices vary every quarter, via its batteries. Fraunhofer said that in this market a trader who is connected to the energy community decides every quarter whether there is a marketing option that can only take a few minutes.
The Fraunhofer team said that these connections position the energy community as a “flexible virtual power plant that can both provide energy and absorb.”
Matthias Klein-Schlößl, leader of the Green by IT team at Fraunhofer ITWM, says that the vision of the Fraunhofer is that the technology will be accessible to private households and companies.
“Everyone who has a photovoltaic system, battery storage or other flexibility, such as a heat pump and electric vehicle, must be able to connect and actively participate in a wide range of energy and flexibility markets,” said Klein-Schlößl.
