基于改进扰动观察法的光伏MPPT控制
Photovoltaic MPPT Control Based on Improved Perturbation and Observation Method
摘要
Abstract
Aiming at the problems of slow tracking speed,low tracking accuracy and easy oscillation of traditional perturbation and observation method(P&O),a maximum power point tracking(MPPT)control method for photovoltaic array based on improved P&O is proposed.The duty cycle is used as the disturbance step,and the power change rate d P/d U and voltage deviation change rate ΔU/ΔPof the photovoltaic array are introduced into the disturbance step,and the duty cycle is adjusted adaptively in real time to achieve faster and more reliable tracking of the maximum power point.The simulation results show that compared with the traditional P&O,the improved P&O has better tracking speed and tracking accuracy under the same conditions.关键词
