About time! Germany faces up to its grid problem with renewables
By: SGN Staff
Quick Take: Power engineering types familiar with the European grid have been warning for years that Germany was going to suffer great pain from its relentless commitment to wind, solar and other renewables. Germany created its aggressive mandates, they warned, without considering the stress they would cause to the grid.
For a while, Germany was able to escape the worst of the problems by using Scandinavian hydro as a "battery" to buffer the intermittency. Now, however, things are catching up with them, and they are finally facing up to the challenge. Or studying it at least, with plans to announce changes shortly thereafter. - By Jesse Berst
Metering.com reports that the German Energy Agency (Deutsche Energie-Agentur) has launched a study called "System Services 2030" to determine how the increasing penetration of renewables will challenge the grid. It will consider various mechanisms to keep supply and demand in balance and to provide ancillary services, including:
Â· Energy storage
Â· Power electronics
Â· Demand side management
Â· Distributed generation
The study will also consider how to balance supply and over greater geographical distances as renewable energy sources expand to include many different countries.
The study will also propose short- and mid-term changes to standards and regulations.
The research partners are ef.Ruhr GmbH and Technical University of Dortmund, under the direction of Prof. Dr.-Ing. Christian Rehtanz. Companies involved include 50Hertz Transmission GmbH, ABB AG, Amprion GmbH, BELECTRIC Solarkraftwerke GmbH, E.DIS AG, EnBW Regional AG, ENERCON GmbH, EWE NETZ GmbH, Mitteldeutsche Netzgesellschaft Strom mbH, N-ERGIE Netz Gmbh, SMA Solar Technology AG, TenneT TSO GmbH, TransnetBW GmbH, Westnetz GmbH, Younicos AG.
