A New Method for Reliability Evaluation of Active Networks

Monte Carlo simulation method is widely used in reliability evaluation of distribution networks. The most important advantage of this method is their simplicity and flexibility to apply to any system. In contrast, large volumes of calculations and inaccurate results are the disadvantages of this method. In this paper, a new method for evaluating reliability indices in active networks is proposed. This method is a combination of Monte Carlo simulation method and analytical method. Unlike the simulation methods, it has a unique answer. Considering that, the purpose of this new method for reliability evaluation is filling gaps in the Monte Carlo simulation method, As a result, the Monte Carlo method will be examined in more detail. To prove the effectiveness of this method, evaluation of reliability indices for bus 2 of RBTS in an inactive network state and in active network state (modified RBTS Bus 2 and 4, including distributed generation resources and Energy storage) using new method and Monte Carlo method have been done and compared with each other. Results of these two methods show that the new method has accurate results and its implementation time is less than the Monte Carlo method.
