1. A method for mitigation of low-frequency oscillations of a power system network, comprising:
receiving a plurality of data sets from the power system network, wherein each data set of the plurality of data sets comprises a terminal voltage value, a real power value and a reactive power value;
receiving a pair of predetermined parameter values of the power system network, the power system network having zero low-frequency oscillations with the said values;
subjecting the plurality of data sets to a fuzzy c-means clustering technique to create a plurality of clustered data sets;
subjecting the plurality of clustered data sets and the pair of predetermined parameter values to a deep learning technique to generate a pair of parameter values;
subjecting the pair of parameter values to a whale optimization algorithm to generate an adjusted pair of parameter values; and
applying the adjusted pair of parameter values to a power system stabilizer coupled to the power system network for mitigation of low-frequency oscillations of the power system network.
