mtu battery storage systems shave peak loads induced by E-vehicle super-charging
The SYNERG-E project is to provide the solution to both these challenges: operators of super-charger stations can be sure of a reliable power supply, while transmission system operators benefit from extra electrical power. With that end in mind, Austrian electricity company Verbund Solutions and E-mobility providers Smatrics and Allego have joined forces as project partners. Between 2018 and 2019, they set up supercharger stations at three locations in Austria – in Innsbruck, Bergkirchen and Feldkirchen near Graz. Each is equipped with four charging points able to power up an E-vehicle in just a few minutes. Three further locations are planned.
The key role in the project is played by mtu-brand stationary storage batteries from Rolls-Royce which provide the much-needed buffer between the charging stations and the utility grid. “The mtu-brand EnergyPacks QM each deliver 500 kVA/ 550 kWh for performing peak shaving at times of high demand,” explained Alexander Flunk, project manager at Rolls-Royce Solutions Berlin (formally the Qinous company). “They help to avoid the high network charges that arise during peak hours and render the charging stations invulnerable to overload situations occurring on the local power grid.” mtu battery storage is central to the highly cost-effective microgrid solutions being offered by Rolls-Royce. mtu storage batteries make a positive contribution to energy sustainability and secure a reliable power supply that meets the needs of individual customers.
Surplus power for the operating reserve market
“The system as a whole basically comprises the grid connection, battery, charging points and microgrid management system. As operators, we gain from the two core functions that our super-reliable mtu-brand storage batteries perform in our project,” explained Karl Potz, head of Power Solutions at VERBUND Energy4Business GmbH. “Not only do they smooth out the fluctuations in the local power demand caused by supercharger stations, they also provide additional grid services for transmission system operators.” The surplus energy stored in the batteries is marketed by VERBUND Energy4Business as operating reserve, thereby helping to counteract stability problems in the public utility grid.
