Abstract: This research article presents a method for selecting an improvement approach for the power distribution system by analyzing financial losses caused by faults in the system. These losses can be in two parts: the first part arises from power outages, which lead to lost sales, estimated opportunities, and expenses for resolving the outages, while the second part results from voltage sags that affect sensitive electrical equipment. The method involves simulating faults at various points in the distribution system and assessing their impact on industrial, commercial, and large-scale electricity consumers. The results demonstrate that by combining the total financial losses from both parts and comparing these losses before and after implementing system improvements, effective and economically viable decision-making information can be obtained for enhancing the power distribution system.
