New solutions for a better distributed generation integration to MV and LV networks

The French DSO (ERDF) is currently studying production flexibility both on active and reactive power in order to help a better integration of Distributed Generation on the MV and LV networks. In order to maximize the hosting capacity of existing MV feeders, since February 2016 ERDF allows Generation facilities connected to medium voltage to perform a local voltage dependant reactive power regulation (Q=f(U)). Likewise, as an alternative to the “standard method” which consists in designing network facilities to evacuate the full production of DGs at any moment, ERDF is studying and testing on real generation sites connection contracts which includes active power curtailment. ERDF is also launching the development of an on-line simulation tool in order to help the connection request on LV networks, by allowing the requesters to fine-tune their connection power and location.
