Kalman估计在光伏系统MPPT中的应用研究
Application research of Kalman estimate in photovoltaic system MPPT method
摘要
Abstract
In this paper, a new MPPT control strategy was proposed by combining the perturbation & observation method and Kalman estimation based on Singer model. The maximum power point voltage range was posted by the larger step length perturbation & observation method. Converted to a small step voltage in the voltage range, the sampling current was measured, the measurement error the current value was weakened by Kalman estimation based on the singer model, the current state mutation was detected by maneuver detection, and the power maximum power point was adopted by calculation and comparison the power. The strategy improved the tracking accuracy, and solved the problem of misjudgment in the perturbation & observation method. The correctness and effectiveness of the strategy was verified by simulation.关键词
