Gap analysis of future energy grids

Based on existing low and medium voltage grids from distribution system operators and future scenarios of PV and EV penetration, critical load scenarios which lead to violations of relevant KPIs are to be developed in the scope of PlanGridEV. In the course of the gap analysis the expected limits of DER hosting capacities were identified. The method for developing and simulating the different scenarios is following a state-of-the-art approach. Results for each power grid and scenario are addressing specific KPIs. The main goal of this analysis was to assess the current EV and PV hosting capacity of existing low voltage and medium voltage grids and identify the factors which limit this hosting capacity. It is shown that European DSOs share similar structures. Depending on voltage level and topology type, specific KPIs were violated by increasing numbers of RES or EVs. Indications for synergies between PV and EVs could be identified due to an increased hosting capacity in the extra PV scenario.
