Abstract—In recent years, the application of Distributed Generators (DG) is increasingly growing in the power systems. Moreover, it is predicted that it will play a significant role in future distribution systems. Nevertheless, incorporating DG into the distribution system alters the structure of the distribution system. This change could have either positive or negative impact on the system reliability which could be determined by DG’s size and location. This paper proposes sequential Monte Carlo simulation to evaluate the reliability indices. Moreover, the Genetic Algorithm (GA) is utilized to determine the optimal location and size of DG based on reliability indices. The objective function of the aforementioned optimization algorithm is the loss minimization and confining within the voltage constraints. This paper presents electric system reliability analysis. Additionally, the optimal size and location of DG is determined with considering the loss and voltage constraints. Moreover, by employing Monte Carlo simulation, the distribution of reliability indices is calculated in addition to the average and expected values.
