Zusammenfassung:	The present invention relates to a method of calculating power system impact according to virtual power plant response, which includes the steps of: collecting power system information from a distribution system including a virtual generator (VPP); detecting voltage/current information of a specific bus bar by performing power flow calculation based on the collected power system information; determining the area of a conclusion member function for fuzzy inference using the voltage/current information of the specific bus bar and a predefined conditional membership function; and calculating a power system impact index of the specific bus bar by applying the center of gravity method to the area of the conclusion membership function. 본 발명은 가상발전기 응동에 따른 계통 영향성 평가방법에 관한 것으로서, 가상발전기(VPP)를 포함하는 배전계통으로부터 계통정보를 수집하는 단계; 상기 수집된 계통정보를 기반으로 조류계산을 수행하여 특정 모선의 전압/전류 정보를 검출하는 단계; 상기 특정 모선의 전압/전류 정보와 미리 정의된 조건부 멤버십 함수를 이용하여 퍼지추론을 위한 결론부 멤버십 함수의 면적을 결정하는 단계; 및 상기 결론부 멤버십 함수의 면적에 무게중심법을 적용하여 상기 특정 모선의 계통 영향성 평가 지수를 산출하는 단계를 포함한다.
