TÓM TẮT
STATCOM is used to adjust bus voltage by injecting or absorbing the reactive power, therefore it is capable of improving power system voltage stability. However, it is important to find theoptimal location and sizing of the device in a power system to support bus voltage in steady-state and design a controller to enhance transient voltage stability. In this paper, the optimal location and sizing of STATCOM are used based on the PSO method and the online ANFIS controller is designed for STATCOM to improve transient voltage stability under large disturbance. Online training of ANFIS is done using a neural identifier. And based on this identification, the weights and coefficients are adjusted timely. To demonstrate the performance of the proposed controllers, simulation results of the voltage response in time-domain are performed in MATLAB environment to evaluate the effectiveness of the designed controller for STATCOM.
