Power Distribution System Improvement Considering Damage Cost Due to Voltage Sags

This research article presents a decision-making guideline for the improvement of the power distribution system. By considering the damaging effects of voltage sags caused by faults in the power system. The damage can be estimated by estimating the number of voltage sags by simulating the occurrence of faults at various locations in the power system, namely industrial, commercial and large power users that are installing equipment that is sensitive to changes in voltage. From the test processing with the proposed technique, it was shown that the results of the damage assessment before and after the improvement of the power distribution system are compared with the cost of improving the power system to reduce the number of faults. It will provide information that can be used to make investment decisions to improve the power distribution system more efficiently and economically.
