Reliability analysis of generating systems including intermittent sources

Abstract A new method for the calculation of expected unserved energy of large-scale power systems including intermittent energy sources like hydro power units, wind turbines and photovaltaic units is presented. The correlation between hourly load and intermittent energy supply is accurately accounted for by the hourly application of a mean capacity outage table. The propose method is efficient, because it eliminates the need for hourly computation of a system negative margin table. In addition, expressions are given for computing the loss of load expectation and loss of load frequency. The method is applied to the IEEE reliability test system which is extended with intermittent sources in the form of wind turbine units.
