We seek to determine the reliability of Intelligent Power Routers (IPR) and the reliability change of an electric power system (PS) operated with and without IPR. The IPR is our module to provide scalable coordination in a distributed model for the next-generation PS. To calculate the change in PS' reliability operated with and without IPR, the IPR failure mechanisms and probabilities must be determined. Since there is no data on IPR reliability its failure mechanisms and probabilities will be estimated. We establish the failure modes for each IPR's element to estimate the IPR reliability, and simulate the behavior of a PS to measure its reliability change. The method used to capture this change, known as risk assessment, uses the probability of occurrence of an event and the impact that it produce. The procedure is discussed, and an example is presented using the 179-bus system for a given operating point. |
