This paper presents a probabilistic approach for the calculations of the expected power loss in distribution systems with large number of DG units. In the proposed approach, the uncertainty of the operating mode (on or off) of each distributed generator and hence, its contribution to the total current of the feeder is modeled as a random current phasor. The total system power loss is calculated by performing a probabilistic summation of all the injected DG currents and multiplies the squares of the current magnitudes with the appropriate resistance. The proposed approach is employed to perform the power loss analysis of a typical distributed generation system involving several DG units and the results obtained are presented and discussed.
