Valutazione della stabilità transitoria dei sistemi elettrici aeroportuali in presenza di grandi perturbazioni e scenari di elettrificazione: analisi e soluzioni per l’aeroporto di Milano Malpensa

The reliable operation of an airport’s electrical grid is fundamentally tied to the resilience and stability of its distribution network. This thesis investigates the transient behavior and fault tolerance of the Malpensa Airport power distribution system under a range of disturbance scenarios. Using a simplified yet dynamically representative grid model, the study analyzes several fault conditions within the network, including a critical fault on the external Terna high‑voltage grid, faults occurring near or within A2A’s generation facilities, and remote faults along the airport’s low‑voltage loops. These scenarios aim to assess the system’s transient response, overall robustness, and flexibility in the presence of faults. As part of the airport’s broader electrification and decarbonization initiatives, a 10 MW photovoltaic (PV) system will be integrated into the grid model. Consequently, the influence of this renewable energy source on the network’s transient stability—particularly during islanded operation—must be thoroughly evaluated. This thesis bridges the gap between renewable energy integration and grid stability by providing a framework to enhance the reliability of airport infrastructure through the assessment of transient resilience and fault tolerance.
