Abstract: In order to realise the power quality stability control of solar power generation, this paper proposes a power quality stability control algorithm based on fuzzy feedback regulation. The iterative control parameter tracking model of the power quality stability control of solar power generation is established, and the error feedback tracking method is used for stable adjustment. The tracking error adaptive compensation method is used to improve the steady-state operation characteristics of the solar generator motor and the control parameters are optimised to achieve the power quality stability control of solar power generation. The results show that after t = 1.5 s, P converges gradually. It proved that the stability of power quality control of solar power generation is good, the self-adaptive regulation ability is strong, and the output quality of solar power generation improved.
Keywords: solar power generation; power quality; stability; control; fuzzy feedback.
