The incoming challenge of the energy transition will strongly involve the distribution system operators (DSO). The rising importance of the electricity source, the growing urban populations, and the use of alternative energies are only some of the key factors that will transform rapidly DSOs. The need to manage unpredictable flows will transform DSOs from pure distributor to dispatchers. In this context, grid resilience will become crucial to ensure the continuity of electrical service in urban areas. Shortening service restoration, thanks to technology upgrading, will improve resilience. Therefore, optimal sizing and positioning of automatic and remote-controlled switches, as well as knowledge of the effect of operational variables on the grid, will become essential for a DSO. Many studies have been conducted so far using heuristic approaches. However, the complexity of these problems grows exponentially with large grids. Consequently, numerical approaches are not suitable for operational development-planning and maintenance interventions. In this work, we derive a simple approximate analytical model which allows to make a prediction of the penalties that the DSO will pay due to user disconnections. The model relies on key constitutive and operational variables, and enables its application to optimize grid development. The model’s simplicity brings the operators working on the grid closer to the problem. Moreover, its analytical nature aims to raise awareness about the relationships among the main variables responsible for the fault selection.
