摘要
Abstract
The output power of the PV array will be changed due to the light intensity and temperature change. In order to ensure that the output of photovoltaic array is always at maximum power point and increase the power generation efficiency of the photovoltaic power generation system,the maximum power point tracking technology needs to be adopted. For oscillation and misjudgment problem of perturbation and observation method based on fixed-step and considering requirements of the speed and accuracy,an improved algorithm that is a perturbation and observation method of the combination of hysteresis comparison and successive approximation was proposed. On the basis of analyzing mathematical models,the three-phase grid-connected PV system model was built based on PSCAD/EMTDC,the traditional perturbation and observation method based on fixed-step and improved algorithm were compared and analyzed through simulating,correctness and validity of the improved control algorithm is verified.关键词
