Stage: PROBLEM TO BE SOLVED: To provide an index capable of performing the same evaluation on stabilization effects due to electrical control of a synchronous generator and a renewable energy power source, and an electrical control algorithm using the same.SOLUTION: A power system stabilization device determines an electrical control target to implement stabilization control in the case of fault occurrence in a power system in accordance with stability in the case of assumed fault in a power system including a synchronous generator and a renewable energy power source. The power system stabilization device comprises: an acceleration synchronous generator determination section for determining an acceleration synchronous generator based on a transient stability calculation result in the case of assumed fault in the power system; an electrical control candidate determination section for determining electrical control candidates for the synchronous generator and renewable energy power source based on the transient stability calculation result; a sensitivity average value calculation section for calculating sensitivity of a speed reduction index of the acceleration synchronous generator with respect to the electrical control of an electrical control candidate and calculating an average value of sensitivity of the acceleration synchronous generator; an electrical control target selection section for selecting the electrical control candidate as the electrical control target in a descending order of average values until transient stability of the power system is stabilized; and an output section for outputting results of the respective sections.SELECTED DRAWING: Figure 1 (Grant)
