ConnectedEnergy solutions in use at Smart City Rheintal

Smart City Rheintal

The Virtual Power Plant of the Smart City Rheintal


"Smart City Rheintal" is a consortia of several forward-looking projects in the state of Vorarlberg in western Austria that share the goal of attaining CO2-free energy autonomy by 2050.

Dipl. Ing. Christian Eugster, project manager Smart City Rheintal:

“The central idea behind Smart City Rheintal is to link technological and societal innovations together and then implement them in a way that benefits people in the region. Bosch is our partner in setting up a Virtual Power Plant and is providing precisely the help we need to balance power consumption and generation, with electromobility as a key element in the equation.”


Virtual Power Plant

In the Smart Grid sub-project, Bosch Software Innovations and its project partners are developing a Virtual Power Plant for the monitoring and management of distributed power generation and demand. Using load distribution, the region is aiming for coordinated energy balance as well as offering new energy services based on the existing infrastructure.

Currently Bosch Software Innovations is implementing three key projects for the Virtual Power Plant Smart City Rheintal:


Monitoring power generation of PV systems and pools

A group of PV systems is aggregated to power generating pools. These pools form the base for an available local energy supply. Therefore the PV systems’ de facto capacities have to be measured and, in combination with weather forecast data, day-ahead forecasts for power generation are provided.


Load management for charging infrastructure of electric vehicles

To integrate the charging infrastructure of electric vehicles into load management, eMobility services access the charging infrastructure (vehicle-to-grid) by using the OCPP protocol. Vehicle-related data, such as the latest SOC (state of charge) or reservation data, are being used to forecast energy consumption. Hence an optimized schedule for charging is calculated and used to access the charging infrastructure.


Control & energy management of in-house consumers

Predicted consumption data is used for instance for managing electric water heater or heat pump demand. On the basis of defined threshold values, commands can be transmitted in order to manage local consumers. The energy management system makes decisions about switching devices on or off. Algorithms are being used to realize different shifting strategies, e.g. on the basis of pricing signals or via schedules.


Other ConnectedEnergy projects

Bosch Software Innovations is involved in a variety of other projects whose benefits spectrum ranges from trans-regional load balancing through Virtual Power Plants (VPP) over regional consumption optimization (micro-grid) to on-site consumption by producers themselves (nano-grid).
