CES and TCSC based Supplementary Controller for Stability of Renewable Energy Integrated Nonlinear Power System

This paper presents the application of the donkey and smuggler optimization technique (DSOT) a recent population-based iterative algorithm tuned tilt-integral-derivative plus filter (TIDF) for interconnected power system (IPS) stability. Two-area nonlinear power system (TANLPS) with the geothermal power plant (GTPP) integrated model is deliberated and constituted the investigation for 10% step load disturbance (10%SLD) on area-1. However, the DSOT-based TIDF efficacy is exhibited with other control techniques, and to further enhance the TANLPS performance the supplementary control mechanism of capacitive energy storage (CES) and Thyristor controlled series compensator (TCSC) is adopted. Simulation results showcased the benefit of adopting the CES-TCSC mechanism to the TANLPS and sensitivity analysis is carried out to showcase the control strategy robustness.
