Abstract: The criterion for eva‎luating a system's ability to adapt to the resilience of the distribution system is usually a necessary recovery from significant power outages caused by extreme weather events such as strong winds and tornadoes. These outages lead to significant economic losses in the system. Recent disasters in the world, especially in the United States, have seriously threatened the health of distribution networks. From this point of view, the need to increase the resilience of the network and the continuity of electricity supply is strongly felt. Due to the ever-increasing presence of distributed generation resources (DG) in distribution networks, to provide load during the failure of the main network and also to improve the resilience of the network, the use of distributed generation resources is one of many important options. comes. In this thesis, we first discuss the concept of DG placement and the objective function of the problem, which in the concept of placement will be cost reduction, which will include reducing losses and costs related to investing in DGs. . Finally, by placing distributed generation (DG) with random errors, the new network created by using voltage/var control problems as well as the re-arrangement problem for optimal utilization for this error (resilience improvement) network) which includes determining the type and optimal location of the capacity of these resources in the network, is discussed and is shown by performing numerical studies on a real distribution network using genetic algorithm (GA).
