5 OSGi Community Event 2013 - OSGi-based management of distributed renewable power sources - EnBW ODR AG, Ellwangen, Germany
Through German legislation the Distribution System Operator (DSO) has to
› set up infrastructure to manage all generation power plants in his own grid,
› to monitor the current power level online of each plant > 100 kW (2.000 units),
› reduce the power level of one or more plants, depending on the grid status with the levels 100% - 60% - 30% - 0%,
› do this job without discrimination.
Currently there are 1.3 millions of renewable power plants in Germany.

Increasing Number of renewable power plants:
› 17% of all buildings have a rooftop PV plant!
› In 2012 the installed generation capacity exceeds 630 MW and is 50% larger than the maximum load peak!
The installation of renewable power plants in our supply area is far above the average in Germany!

Power management @ EnBW ODR AG Backend
IEC-104 sample:
IEC-104 connector registers / unregisters IEC-104 PowerPlant service for each gateway power plant control unit with a specific IEC-104 address property
IEC-104 protocol creates slave instance and waits for master connections
A IECMaster service will be registered for each master connection
IEC-104 messages form the power plant control units will be forwarded to all registered IEC-104 IECMasters
Requests / commands from the IEC-104 master will be forwarded to the PowerPlant services with the matching IEC-104 address property found by a service filter
Benefits:
Different protocols are able to talk “native” to the same gateway / power plant with minimal extra effort (register and track services)
Changes made by one of the protocols are visible for all registered connectors
Control-units are usable via mPRM SOAP/REST API without any extra effort
Control-units are usable via mPRM procedures and scripts without any extra effort
Single set of application firewall rules cover all protocols OSGi Community Event 2013 - OSGi-based management of distributed renewable power sources - EnBW ODR AG, Ellwangen, Germany 13
