The paper considers the case of using a multiple of D-Statcoms with a proposed voltage compensating principle that can be practical for large-size distribution systems. In the paper, the IEEE 33-buses distribution feeder is used as the test system for global voltage sag simulation in the events of short-circuit in the system and various influential parameters to the outcomes of the problem of optimization such as rms voltage threshold and D-Statcom's limited current are considered and discussed. | Optimizing the placement of a number of D-Statcom for improving SARFIX in the distribution system
