This paper deals with power system restoration, and points out the importance of performing periodical extended restoration tests. Field tests should be preceded by accurate simulations, whose aim is to check the system operation and predict possible problems, mainly of dynamical nature, that can arise during the most delicate steps of system restoration. This concept is illustrated and discussed by means of a case-study, concerning the recent study and field test, performed in Italy, of a restoration path with novel interesting features. Aiming to evaluate the significance of the information got through preliminary simulations, simulation results are compared with field test recordings. The problems individuated through simulations, and also the main differences between simulation results and field recordings, are reported and commented.
