Abstract :
This paper deals with the problem of measuring the level of order, in terms of degree of internal organization, of a given power transmission network. The critical nature of such a kind of complex dynamical systems have been already recognized in literature. The paper introduce a novel approach, based on the concept of T-entropy, to compute the level of internal organization of a power transmission network which is assumed as a self-organized critical (SOC) system and thus modelled by using three different topologies which resemble the well known sandpile model. Simulation results show that the critical state of the dynamical system is strictly related to the global of the T-entropy. From here the conjecture, formulated in the paper, to adopt the T-entropy as a suitable measure of the ldquodistancerdquo of the system from its critical state.
