摘要:
为更好地解决光伏MPPT 算法跟踪速度和稳态精度难以兼顾的问题,提出一种新型变步 长电导增量法。此方法先采用可应对环境突变的0.8 倍开路电压法快速跟踪到光伏电池最大功率 点附近,然后利用反余切函数变系数法调整跟踪步长,使系统逐渐稳定跟踪到最大功率点运行。文 中对扰动法、传统电导法及本文所提方法在温度、日照强度突变工况下进行了仿真对比分析。仿真 结果表明,相比扰动法及传统电导法,新型变步长法有着更快的跟踪速度及更高的稳态精度,有效 降低了跟踪时间、减小了稳态功率振荡引起的能量损失。
Abstract:
In order to better solve the problem that the tracking speed and steady?state accuracy of photo? voltaic MPPT algorithm are difficult to balance,in this papera new variable step size increment conductance method is proposed. This method firstly uses the 0.8 times open circuit voltage method,which can deal with environment mutation,to track quickly to the vicinity of the maximum power point of the photovoltaic cell. Then,the anti?cotangent function variable coefficient method is used to adjust the tracking step size to make the system gradually track to the maximum power point for operation. Such three methods as perturbation method,traditional conductance method and the method presented in this paper are simulated,compared and analyzed under the sudden change of temperature and sunshine intensity. It is shown by the simulation result that the new variable step?size method,compared with the perturbation method and the traditional conductance method,has faster tracking speed and higher steady?state accuracy,which effectively reduces the tracking time and reduces the energy loss due tosteady?state power oscillation.
