Redox Flow Battery and TCSC-based Territory Control Mechanism for LFC of Dual Area Reheat Hydro-Thermal Power System

In this paper, Tilt-Integral-Derivative with filter (TIDF) is designed for load frequency control (LFC) of dual area realistic hydro-thermal (DARHT) system. For more practical analysis, a reheat-type turbine structure is considered for a thermal unit. The parameters of TIDF are found optimally using a new evolutionary method known as the donkey and smuggler optimization algorithm (DSOA). However, optimization of TIDF using DSOA is carried out by minimizing the integral time absolute error (ITAE) index. Obtained simulation results demonstrate the sovereignty of the presented controller over PIDD and PID performance. Further, the territorial strategy of redox flow battery (RFB) and Thyristor controlled series compensator (TCSC) devices are employed with the DARHT system to acquire performance enhancement. At last, sensitivity analysis against a high range of load variations is conducted to validate the presented control approach robustness.
