Fractional Complex LMS Control for DSTATCOM in Three Phase SEIG Based Distributed Power Generation

This chapter represents the improvement of the Power Quality (PQ) using a Fractional Complex Least Mean Square (FCLMS) control in the three phase Self-Excited Induction Generator (SEIG) with Distribution Static Compensator (DSTATCOM) under a nonlinear load. This system is one type of distributed power generation system where wind power is converted to electrical power. The proposed control strategy is employed to achieve both reactive and active weight elements from non-ideal load current and is further utilized to trigger the Voltage Source Converter (VSC). The issue of complex errors resulting from complicated input/output or negative weights in the FLMS is resolved through the utilization of the FCLMS control scheme. By implementing the mixing parameter, the convergence rate of FCLMS is improved with lesser steady-state error. The proposed FCLMS control scheme gives better performance under the steady-state and dynamic operating state. Also, it effectively tracks the reference frequency value and sets terminal voltage. Furthermore, an Arithmetic Optimization Algorithm (AOA) is employed for tuning the gains of PI. The percentage overshoot and settling time are the parameters determined for the FCMLS control scheme to show its effectiveness. The MATLAB/Simulink result and its experimental implementation proves the efficacy of the proposed control technique.
