Determination of installation capacity in reservoir hydro-power plants considering technical, economical and reliability indices

One of the most important issues in planning the “reservoir” type of hydro-power plants (HPP) is to determine the installation capacity of the HPPs and estimate its annual energy value. In this paper, a method is presented. A computer program has been developed to analyze energy calculation and estimation of the most important economic indices of an HPP using the sensitivity analysis method. Another program, developed by Matlab software, calculates the reliability indices for a number of units of an HPP with a specified load duration curve using the Monte Carlo method. Ultimately, comparing the technical, economic and reliability indices will determine the installation capacity of an HPP. By applying the above-mentioned algorithm to an existing HPP named “Bookan” (located in the west-north of Iran); the capacity of 30 MW is obtained.
