Title
Fuzzy Pid Controller For Pcc Voltage Harmonic Compensation In Islanded Microgrid
Abstract
In this paper, an intelligent control scheme based on fuzzy proportional-integral-derivative controller (FPIDC) is proposed for PCC voltage harmonic compensation in islanded microgrid. The proposed FPIDC method is composed of a closed-loop control of the virtual impedance at harmonic frequency to absorb the harmonic current from the nonlinear load, control harmonic sharing between distributed generators. As a result, the PCC voltage quality is improved with the total harmonic distortion (THD) significantly reduced. With the feedback of the PCC voltage and well-designed fuzzy controller, the uncertainty and unstable value of proportional-integral-derivative (PID) parameters are removed by adaptive tuning. Therefore, the PCC voltage quality is improved smoothly, and the system becomes more stable even load condition is changed. Compared with the traditional PID controller, the dynamic response and stability of the microgrid system are improved with the proposed FPIDC. The comparison and analysis of the proposed control with the conventional control are carried out to verify the superiority of the proposed method.
