This paper describes a new method of probabilistic power system production cost and reliability calculation using the z-transform. In the proposed method, the generating unit available capacity probability density functions (pdfs) are represented by probability impulses. These pdfs are convolved using the z-transform to produce equivalent capacity pdfs. By operating the equivalent capacity pdfs on the system demand, the unit energies, loss of load probability (LOPLP) and expected unserved energy (EUE) can be calculated for each load level and the total demand. The method is compared with the cumulant method and Calebrese's traditional direct convolution procedure in terms of accuracy and computing time using the IEEE Reliability Test System.
