Abstract  Electric power systems are crucial for sustaining modern economies and technological progress. These systems comprise power plants, substations, and consumers, linked by multiple transmission lines forming a network. This system can be modeled as a multistate electric power network (MEPN), where each link functions with several capacities. Transmission losses, also called loss rates, greatly affect the efficiency of these systems. This paper assesses the network reliability of the MEPN, which is the probability that the network can transmit sufficient power to meet demand in the end, factoring in loss rates. By analyzing the flow in each subnetwork and considering the loss rate, the minimal necessary capacity to satisfy demand in each subnetwork is established. An algorithm is then developed to calculate the network reliability of each subnetwork, thereby determining the network reliability of the MEPN. Finally, a simplified MEPN shows the effectiveness and efficiency of the proposed algorithm.
