The project INCREASE is slowly coming to an end, but some very interesting and important activities of the project are still running, for example network field trials, which are meant for validation of the INCREASE solutions in real distribution networks of European DSOs. Slovenian field trial is being performed by Elektro Gorenjska. The network selected for the INCREASE field trials is located in the village Suha, near Kranj.
The pilot network of Elektro Gorenjska is a nice example of rural cable low voltage network with high penetration of the PV, therefore it was decided that the INCREASE solutions for provision of adequate voltage profile will be tested there, namely OLTC control algorithms and INCREASE local control for prevention of over-voltages via curtailment of PV generation.
Since the early beginning of the project, a lot of activities have been performed by Elektro Gorenjska and other INCREASE consortium partners in order to establish the necessary conditions for the field trial:
So far, most of the commissioning and testing activities have already been performed, all systems and equipment are running good, however some final settings are still required to complete the field trial. The OLTC control algorithm, developed by TU/E has already been tested and it showed some very nice results.
The INCREASE consortium visited the Suha pilot network, during the latest project meeting in Kranj. The picture above is the new transformer station, established as a part of the INCREASE project, while the pictures below present the selected 22 kW PV installation and ILPRA’s equipment for curtailment of the PV production in order to prevent over-voltages.
In the coming weeks, the remaining field trial scenarios will be tested. The results of Slovenian and other field trials will be further presented on the final conference of the project INCREASE on the 11th and 12th of October in Ljubljana, Slovenia.
