【摘要】 针对常规扰动观察法实现光伏电池最大功率点跟踪(MPPT)出现的跟踪速度和稳态精度相矛盾问题,提出了一种改进的变步长扰动策略。该算法通过对光伏电池的输出电压进行调节,从而实现最大功率点跟踪。在Matlab/Simulink下进行系统的建模与仿真,结果表明相对传统扰动观察法有效提高了动态响应速度和稳态精度。更多还原

【Abstract】 For regular perturbation method there exists tracking speed and steady state accuracy of the inconsistent problems during the process of maximum power point tracking(MPPT)? An improved variable step perturbation strategy is proposed?The MPPT is achieved by regulating the output voltage of photovoltaic cell.The system modeling and simulation is carried on Matlab/Simulink,the result shows that the method can effectively improve the speed of tracking and steady accuracy compared with the regular perturbation method?更多还原
