Résumé : The share of distributed generation is steadily increasing in the field of electrical energy production. However, consequently to this shift, in rural areas mainly, grid operators are expecting more frequent line congestions and voltage problems. Active management of the distributed generation units is one of the possible solutions to keep the grid secure, while accepting more connections of this type of units to the existing grid infrastructure: (almost) real-time curtailment is applied to some generators in order to suppress congestion(s) on the grid. However, in the planning phase of the grid, the impact of active management, in terms of e.g. expected curtailed power per year, should be assessed before any possible new connection is allowed. This paper proposes a probabilistic risk assessment to estimate related risk indices, provides the mathematical formulation of the corresponding methodology and gives preliminary results on a simple test-case.
