Dynamic grid support (dynamic network requirements)


Dynamic network requirements refer to the ability of the power generating system to stay connected during grid instabilities. The main requirement is the so called Low-Voltage-Ride-Through (LVRT) request, which defines the voltage dip/time profile range. Within these limits the generating units may not disconnect from the grid. The graph below shows the requested profiles for Germany, Austria, Belgium and France as an example: In the case of grid instability above the specific profiles, the power generation system must stay connected to the grid, below the specific voltage dip profile the power generation system may disconnect.

Customer advantages The new grid code-conforming packages of Jenbacher gas engines offer the following advantages:


• Reduced outage during grid fluctuations • Compliance with country-specific grid codes (FRA, BEL, GER (BDEW), AUT (TOR D4))


• Products for Germany are certified acc. BDEW Technical guideline “Generating Plants Connected to the Medium Voltage Network” (4th amendment)


• Robust generator • Faster excitation system (ABB UNITROL 1010 regulator) and improved protection mean more reliable operation for dynamic grid code packages


Belgium France


Germany Austria


• Contribution to the stable, decentralized power supply of the future


• No “domino” effect in case of system incident


Status In order to cover the various requirements as efficiently as possible, the Jenbacher product portfolio 2016 is standardized in the following four categories:


0 0,15 0,3 0,45 0,6 0,75 0,9 1,05 1,2 1,35 1,5 1,65 1,8 t/s


• Standard (no specific grid code requirement) • Static grid code package • German grid code package (BDEW 08/2008: static and dynamic) LVRT 150 ms / 30 % Voltage dip @ Point of Connection (POC)


• French grid code package (static and dynamic) LVRT 150 ms / 5 % Voltage dip @ Point of Connection (POC)


Details of the packages including the related set points for grid monitoring device can be found in the technical specification. Deviations from these four categories need to be addressed case by case on request: • Special gas versions require a technical release through the special approval process


•Waukesha gas engines are on special release only • The grid code compliance for Heat Recovery Solution products needs to be checked case by case according to the local requirements


• The future ENTSOE requirements are NOT scope of the current standard PP2016
