In recent years, network reliability is one of the major concerns in distribution system and network customers expect distribution companies to provide them high reliability and electrical power with better quality. Distributed Generations have proper effect on system reliability when they can control network in intentional islanding. In this paper with considering DG output and load consumptions in uncertainty mode, probability of supplying load points are estimated and then indexes of network load point's reliability is calculated more accurately. Normal distribution function is used to model load consumptions and DG output power and Monte Carlo simulation is applied to evaluate average annual outage time of load points. Numerical example is presented to demonstrate the efficiency of the proposed methodology.

Abstract


In recent years, network reliability is one of the major concerns in distribution system and network customers expect distribution companies to provide them high reliability and electrical power with better quality. Distributed Generations have proper effect on system reliability when they can control network in intentional islanding. In this paper with considering DG output and load consumptions in uncertainty mode, probability of supplying load points are estimated and then indexes of network load point's reliability is calculated more accurately. Normal distribution function is used to model load consumptions and DG output power and Monte Carlo simulation is applied to evaluate average annual outage time of load points. Numerical example is presented to demonstrate the efficiency of the proposed methodology.
