EU-SysFlex blog: How can distribution system operators better control the distributed generation

04.10.2019News

E-distribuzione intends to demonstrate that the technologies that will be developed or improved within the EU-SysFlex project allow a distribution system operator to acquire total autonomy in the control of distributed resources connected to its own network.

Currently, the distribution networks in Italy are characterized by a high penetration of distributed generation. In 2017, about 31.3 GW of plants were connected to distribution networks which represents 26.7% of the gross national capacity. This can cause voltage violations and congestions. In addition, decentralization of the power system requires an improvement in the observability and the participation of distributed energy resources (DERs) in the provision of ancillary services.

For this purpose, an advanced solution for managing flexibilities connected to the distribution network is going to be developed in the portion of the grid involved in the demo of the EU-SysFlex project. It will also improve the coordination with the transmission system operator (TSO). This is important in situations where, due to the increasing share of renewable energy sources (RES) and to the corresponding decrease in conventional generation capacity, there is a scarcity of resources in the transmission network for providing ancillary services.

In this context, it is important to emphasize that in Italy the division of roles is as follows, …read more
