Description
The paper introduces a new method for optimizing the placement of a multiple of D-Statcoms for voltage sag mitigation in distribution systems. The D-Statcom’s placement is optimally selected not only for improving system voltage sag caused by a single fault event but also for all possible fault events in the system of interest. Therefore, D-Statcom’s placement is optimized in a problem of optimization where the objective function is to minimize the system voltage sag index – SARFIx. D-Statcom’s effectiveness for voltage sag mitigation is modeled basing on the method of Thevenin’s superimposition for the problem of short-circuit calculation in distribution systems. 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. The paper uses the IEEE 33-buses distribution feeder as the test system for voltage sag simulation and influential parameters to the outcomes of the problem of optimization are considered and discussed.
