Zusammenfassung:	In this paper, a simple and efficient algorithm for incorporating STATCOM losses in the load flow calculation is proposed. In this technique, both the STATCOM switching loss and the step-down transformer ohmic loss are accounted for and are calculated iteratively. To reduce the computational burden, the system load flow equations and the STATCOM equations are solved separately. The proposed algorithm has been tested on IEEE 30 bus and IEEE 57 bus power systems. Based on the results obtained on different operating conditions, the proposed algorithm has been found to possess good convergence characteristics. The influence of different factors on the convergence characteristics of the proposed algorithm has also been investigated in detail.
