Abstract EN
This paper presents a Modified Gravitational Search Algorithm (MGSA) to improve the performance of PI controller in varying load condition.
The proposed approach is capable of mitigating reactive power, neutral current, source current THD and significant improvement in power factor nearly unity (0.997).
The DC link voltage across the capacitor is controlled by PI controller which is deciding the performance of shunt APF.
Hence, the robust optimization technique based integral time square error (ITSE) with consideration of weight factor (α & β), maximum overshoot (|Δv_ ______n_ _|) and setling time_t − t__, is providing the optimum solution of Kp & Ki.
The robustness of proposed objective function and algorithm compared with GSA based three other error criterion techniques.
The efficiency of the proposed controller has been tested over nonlinear and unbalance loading condition.
The performance of ITSE based MGSA-PI controller is batter then other three error criterion techniques.
The values of THD are below the mark of 5% specified in IEEE-519 standard.
