Due to Distributed Renewable Energy Sources (DRES), Power Flows are becoming bidirectional and lowering the inertia, increasing the frequency deviations and reducing the self healing reaction efficiency of our modern Power Systems. This high frequency deviation within power system gets a serious problem for todays network operation.
The purpose aims at stabilizing the frequency of the network by controlling the active power of distributed loads / sources with frequency deviation.
Automatic and secure selection of Frequency Containment Reserve (FCR).
Automatic and secure selection of pre-Under Frequency Load Shedding (UFLS).
Targeted DER and DRES: electric heating, hot water tank, electric vehicle, distributed storage and renewable sources.
FCR and possible pre Under-Frequency Load Shedding (UFLS)
The technology (hard and software) has been validated within the EU projct DREAM. Successful testing was realised at the ICCS Lab in Athens, the airport in Milan and the showroom at Schneider Electric. Further tests in the lab on real netword simulations have been carried out. Data was managed with a cloud based plateforme in Lille.
