The benefits of the photovoltaic distributed generation (pvdg) installation in the distribution network include the total system loss reduction, voltage profile improvement and the reliability enhancement of the distribution network by minimizing the interruption and duration time to customers due to the loss of utility or due to the faults in transmission lines/equipments. in this research, the optimal size of pvdg is connected at the optimal location of practical distribution network (town pyone feeder). The multi-state model is used to calculate the probabilities of the solar irradiance data and the output power of pvdg. These probabilities of solar irradiance are applied to assess the reliability of the practical distribution network with pvdg integration. The reliability within the island operation mode of the distribution system with pvdg is presented. Analytical approach is described to assess the impact of pvdg on the system reliability due to the stochastic behavior of pv output power. a composite index organizing the impact of pvdg on the overall reliability of distribution network including interruption frequency, interruption duration and expected energy not supplied is presented. The results show that the integration of pvdg placement in the practical distribution network can improve the reliability and the applying proposed methodology can enable determining pvdg configuration concerning the overall system reliability improvement.
