Vattenfall Europe New Energy GmbH and Vattenfall Europe Wärme AG seem to be ahead of many other utilities in implementing “virtual Power Plants”. They have set a standard on how to use renewable energy in a virtual power plant. The information exchange is realized with two IEC TC 57 standards: IEC 60870-5-104 (Fernwirktechnik) and IEC 61850-7-420 (DER).
Vattenfall is one of the leaders of the implementation of virtual power plants. The concept is called: VHP READY – Virtual Heat & Power Ready.
Their objective is by end of 2012 to provide their services to 150.000 housing units (with some 500 CHP or heat pumps) communicating with a Vattenfall control center. By 2013 they expect some 1,000 CHP or heat pumps providing heat and electric power to some 200.000 housing with an electric capacity of 200 MW.
The requirements document lists a total number of signals of 40:
- 8 binary status signals,
- 17 measurements and calculated values,
- 5 metered values, and
- 10 control points.

Several other projects are under way in Germany to implement a similar approach. In one project there is already a plan to define (and possibly standardize) a specific profile (subset) of IEC 61850-7-420. Such a profile would represent the above some 40 signals – a very simple set of models that could easily be implemented in an IEC 61850 IED like the Beck IPC IEC 61850 com.tom:
