Software instead of copper coils

Bosch Software Innovations makes Berlin’s grid smarter

From now on, Berlin-Britz will be known for more than just its beautiful Britzer Garden – it’s going to be recognized as a leader in contemporary energy management. Since September 18, the neighborhood’s substation – belonging to the Vattenfall subsidiary Stromnetz Berlin GmbH – has been the first in Germany to employ a new, radio-based ripple control system. Bosch Software Innovations helped flip the switch by designing the system’s IT platform and control logic.

IT for more efficiency than ever

This new technology replaces the audio-frequency ripple control method used until now, which transmits on and off signals to connected decentralized electricity consumers via the power grid. Thanks to Business Process Management, a component of the Bosch Software Innovations software suite, controlling these plants is now significantly more efficient and exact.

Using radio signals means not only energy consumers but now also energy suppliers can be switched on and off or regulated in steps, and facilities receiving parameter settings from remote. This is an extremely convenient way for Stromnetz Berlin GmbH employees to control photovoltaic plants, heat pumps, combined heat and power (CHP) plants, lighting, night storage heaters, and charge spots for electric vehicles. Thanks to the e*Nergy service provided by project partner e*Message, control signals are tamper-proof and can be transmitted throughout Germany – because even thick concrete walls around a receiver will not block radio signals. The radio-based system is already in use with the first of some 25,000 households and 1,400 commercial customers.

The broadcast system helps grid operators reduce operating costs

The new radio-based ripple control technology offers other tangible benefits – not just for Stromnetz Berlin but for all grid operators. It is significantly less expensive, more efficient, and more space-saving than the units required in each substation for the audio-frequency method. When compared to conventional audio-frequency ripple control technology, this results in a significant reduction in operating costs and palpable opportunities for increasing efficiency or operators margins.
