Abstract
This paper presents a performance evaluation approach for electric power distribution systems considering aspects related with service adequacy and security, as well as islanded operation. In this approach, a Sequential Monte Carlo Simulation based procedure is applied to emulate the distribution system operation, as well as to calculate system and load point performance indices. Steady-state aspects are evaluated using AC power ow computations. Furthermore, frequency stability is assessed using dynamic simulation aiming at verifying the feasibility of islanded operation. Simulation results are presented for modi ed versions of the RBTSBus2- F1 test system. The results highlight the importance of including steady-state and dynamic analysis into the system performance evaluation, mainly in what regards the impact assessment of distributed generation on the distribution system operation.
