Hybrid wind-PV farm with STATCOM for damping & control of overall chaotic oscillations in two-area power system using hybrid technique

This manuscript proposes a hybrid wind-photovoltaic farm with static synchronous compensator(STATCOM) for damping and controlling general chaotic-oscillations in a two-area power system. The proposed hybrid method is the joint operation of Tasmanian Devil Optimization(TDO) and Aquila Optimizer (AO) and together called as TDO-AO technique. The major objective of the proposed technique is minimizing the error, optimizes the performance of the system and regulates the controller parameters of proportional-integral (PI). The STATCOM is used to regulate the voltage and improve the power-factor of the system, leading to better power quality and reduced losses. The TDO is used to optimize the location and size of the wind-PV farm. The AO is utilized to enhance the parameters of STATCOM. The hybrid wind-PV farm with STATCOM can provide a renewable source of energy and improve the stability and reliability of the power grid. While being optimally compensated, the system is vulnerable to 3-phase faults. Zero damping is one more disturbance, along with a change in reference voltage and electric torque. The disturbances are created to simulate the worst scenarios, so that the hybrid wind-PV farm may be rigorously evaluated for its effectiveness in reducing the total chaotic oscillations. In Wind-PV-STATCOM, the gate signal is managed by a controller that separately controls the AC and DC currents. Then, the performance of proposed method is implemented in MATLAB and it is contrasted with the existing methods. From the simulation analysis, the proposed method based settling time is 1.00 sec that is less than the existing one.
