Abstract

The penetration of Plug-in Electric Vehicles (PEVs) is becoming more and more increasing. PEV charging demand will be satisfied by different charger types (domestic at LV level and fast at MV level). Such charge could determine criticalities in the distribution network that can be solved, excluding the resort to expensive reinforcements of the network, through the exploitation of distributed energy resources (DER) flexibility. If such criticalities occur at the MV level, the needed flexibility can be acquired from the underlying LV networks. The paper presents the exploitation of LV flexibility for solving MV network operation issues. Regarding the flexibility quantification, it is assumed that the LV is equipped with an LV multi-agent system for active management. An example derived from a real case is proposed and discussed.
