Renweable energy resources degrade network inertia, thereby frequency stability is worsened. Grid-forming converter aids to stabelize the frequency measures after disturbance by applying virtual inertia to counter the reduced system inertial response. However, some challenges are encountered due to the PID control parameters setting and the virtual inertia value selection

Make use of battery energy storage system (BESS) to regulate frequency measures after introducing wind power source. The secondary frequency control is the main application of utilizing the BESS
