Using EDSA on radial primary feeder capacitor size and location simulation

The radial primary distribution feeder capacitor size and location optimization conducts calculations with the objective to minimize the total cost. It also provides a solution regarding the capacitor size and its location. On this purpose we use EDSA Technical 2000 program for an example primary distribution feeder from a radial distribution system. The paper presents also the results of EDSA Technical program performing calculations for a distribution system load flow. On the other hand, the installation of a capacitor requires an investment cost. Therefore, a compromise should be made in order to determine the size and the location of a capacitor on the primary distribution feeder. The objective of simulation is to minimize the total cost of the substation KVA charge, of energy loss cost and of capacitor investment.
