From the perspective of power flow distribution

SVC is a kind of feedback compensation measures. Its influence can be deemed as a kind of space topology transform of the relevant variables

thus

equivalently assuring partial topology of power system. Therefore

it is very important on how to select installation location of SVC. The bus participation factor of each load busbar is calculated through modal analysis

the weak busbar and area are determined through magnitude of busbar participation factor

thus determining optimal installation location of SVC. Moreover

this method is used to improve static voltage stability of Nanjing power network

thus providing theoretical basis and application reference on the selecting installation location of SVC.
