ABSTRACT

OSGi-based management of distributed renewable power sources

The presentation will provide an overview of the architecture and implementation of the infrastructure that will be used at EnBW ODR AG to manage distributed renewable energy sources.

In Germany, a electrical distribution system operator (DSO) is authorised by the legislator to limit the production of energy, if stability of the power grid is endangered or the grid is not capable to transport the renewable or conventional generated energy. Due to the installation of 1.2 million distributed renewable generating facilities, this instrument is used almost daily by some DSOs. The capability of the DSO, to measure the current power and to limit the energy production, have now to be implemented for all renewable power plants bigger than 100kW.

At first, we were looking for a turn-key solution in the market, that offers automatic provisioning, dynamic software-updates, hardware independence and process integration plus some additional management features. Due to the fact, that no existing software solution was able to fulfil our requirements (these all is needed because of the vague legal situation), we decided to implement a prototype based on a public standard that is widely accepted, OSGi.

Eclipse Equinox is in use as runtime on the gateways and ProSyst mPRM device management software are implemented on the back-end side. The gateways communicate with the local automation units at the renewable energy plants using protocols that are common in industrial automation. The 3G-based gateway communication to the back-end is implemented using SSL-encrypted messaging services. Registered gateways appear in the back-end as so-called power-plant- and generator-control-units with a defined feature set. An OSGi bundle on the mPRM back-end tracks these control-units and handles communication to the control center, using the telecontrol protocol IEC 60870-5-104. Currently the integration and rollout of gateways for 1,000 power plants starting in Q1/2014, is carefully arranged.

About EnBW ODR AG EnBW ODR AG is a regional subsidiary of EnBW AG (the 3rd biggest energy supplier in Germany) and supplies about 220,000 customers with electricity in a rural area of 3,400 km². Currently there is an installation of 25,000 renewable generating facilities in our electrical grid, rising about 2,500 every year. 380 employees work in the head office, which is located in Ellwangen. http://www.odr.de

    • Agenda › About EnBW ODR AG › The Smart Grid challenge: Managing distributed renewable power sources › Why OSGi? › The way we compete the challenge › Q&A OSGi Community Event 2013 - OSGi-based management of distributed renewable power sources - EnBW ODR AG, Ellwangen, Germany 2
    • We offer innovative solutions in Energy and Telecommunications Business Segments 1 2 3 Purchase and sale of electricity & gas Operation of the distribution grid for electricity & gas Internet Service Provider (ISP) and Carrier with own infrastructure supply area & key indicators Würzburg Ostwürttemberg 90 municipalities › › › › › 200.000 electricity customers 15.000 gas customers 400 employees 450 Mio.€ sales Supply area: 4.500 km² with 450.000 people HQ: Ellwangen Stuttgart Bavaria 40 municipalities 4 Energy related Services Ulm OSGi Community Event 2013 - OSGi-based management of distributed renewable power sources - EnBW ODR AG, Ellwangen, Germany 3
    • Where are the different types of generation plants connected to the electricity grid? Power Plant Transformer Station Transformer Station Transformer Station Customer G 20 kV 0,4 kV High Voltage Grid Medium Voltage Grid Low Voltage Grid Large regional Distribution Grid Small regional Distribution Grid Lokal Distribution Grid 380/220 kV 110 kV Maximum Voltage Grid European & nationwide Transmission Grid Wind Offshore, conv. generation Wind onshore PV, Wind, Biomass PV OSGi Community Event 2013 - OSGi-based management of distributed renewable power sources - EnBW ODR AG, Ellwangen, Germany 4
    • Necessary for power management in the electrical grid (EnWG §11 & §13) 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. OSGi Community Event 2013 - OSGi-based management of distributed renewable power sources - EnBW ODR AG, Ellwangen, Germany 5
    • The installation of renewable power plants in our supply area is far above the average 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! 50.000 25.000 21.000 17.000 4.000 2005 2010 2011 2012 2020 forecast OSGi Community Event 2013 - OSGi-based management of distributed renewable power sources - EnBW ODR AG, Ellwangen, Germany 6
    • There are very different consumption und generation load profiles over a year - load of a 110/20kV transformer Energieverbrauch durch EEG gedeckt Energieverbrauch durch konv.

    • Power management @ EnBW ODR AG Registry based gateway addressing using control units 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
