为了减少环境变化引起的功率损耗，提高光电转换效率和跟踪速度，在传统电导增量法和自适应变步长LMS算法的基础上，提出了一种新的自适应MPPT算法，通过Matlab的SimPowerSystem模块，本文建立了光伏电池的仿真模型和自适应变步长MPPT算法控制器，仿真结果表明，该算法能快速找到新的工作点，具有良好的动态和稳态性能，验证了该算法的有效性。
In order to reduce the power loss caused by changeable environment,and to increase the photoelectric conversion efficiency as well as tracking speed,a novel adaptive MPPT algorithm based on traditional increment conductance method and adaptive variable step size LMS algorithm was proposed.By SimPowerSystem block of Matlab,the simulation model of photovoltaic cell and adaptive variable step size MPPT algorithm controller was built in the paper.Even under the perturbations of illumination and temperature,simulation results show that the proposed algorithm can quickly find a new operating point and has a good dynamic and steady-state performance,which confirms the validity of the novel algorithm.
