Abstract. Due to its widespread applications, electrical energy has always been of great importance so that a power outage even for a moment may cause many irreparable problems. Power outage or shortage may occur for different reasons including the loss of energy in the electric distribution network. Loss of energy will impose enormous costs to the government. In this regard, the aim of this study is to identify the factors causing the loss of energy in the electricity distribution networks. By further understanding of these factors, their impact on the distribution networks can be largely reduced. The lack of knowledge on the regions with high loss of energy and the importance of each indicator in a particular area will result in more energy loss by diverting the decisions of managers and decision-makers from the main goal. Twelve experts from the electricity industry participated in this study. The comments by the experts were collected using a questionnaire. Using the theoretical background and the Likert scale, the parameters affecting the energy loss in the distribution networks were identification. These indicators include energy theft, measurement errors, load, network aging, loose connections, improper placement of equipment, voltage, resistance of the conductor, losses from equipment, the location and size of capacitors, geographical conditions, size and dimensions of the conductor, current leakage and network configuration. Using the Cardinal weights, the indicators were weighted and ranked in Assaluyeh, Bushehr and Deylam in Bushehr province. The most important factors affecting energy loss in Assaluyeh, Bushehr and Deylam include energy theft, the location and size of the capacitors and network configuration, respectively.
Keywords: loss of energy, Cardinal weights, electricity distribution network.
