Abstract
The paper aims to analyse how small-scale renewable energy sources (prosumers in low voltage distribution networks) should modify planning strategies for electric distribution networks (EDNs) considering additional energy generation. By injecting energy locally, prosumers can minimise energy losses and balance the generated and demanded power within the EDNs. With the efficient utilisation of renewable energy potential and significant investments in the technical infrastructure, Distribution Network Operators (DNOs) can facilitate optimal planning for the transition towards active EDNs. In this context, the proposed framework integrates a scenario-based resilient planning software tool for low-voltage EDNs, considering various cases regarding the penetration degrees and energy production of prosumers and load demand at the end-user level. The results from steady-state calculations across all scenarios, built upon combinations of all cases related to penetration degree, energy production, and load demand, highlighted the development and planning challenges that DNOs may encounter in certain situations. In this context, the proposed framework enables the identification of the technical solutions necessary for the optimal operation of future active electrical networks from the planning phase.
