Transient Stability Assessment Method of Power Systems Based on ADASYN and GRU
With the wide-area interconnection of power systems and the increasing complexity of structures,the accurate assess-ment of transient stability of power systems has received more attention.Therefore,a transient stability evaluation method of power system based on adaptive synthetic sampling and gated recurrent unit is proposed.Firstly,the adaptive synthetic sampling algorithm was used to deal with the imbalance of power system sample categories,and minority samples were synthesized.Then,the gated recurrent unit evaluation model was trained using the resulting balanced sample set.Finally,when applied on-line,the real-time data collected by the phasor measurement unit was input to quickly evaluate the transient stability of the pow-er system through the trained gated recurrent unit.The simulation test was conducted on the 23-node system provided by the power system simulation software PSS/E,and the simulation results confirmed the effectiveness of the proposed method.
