基于dP/de的太阳能发电系统最大功率控制方法

Maximum power control strategy for photovoltaic power generation system based on dP/de

在光伏发电系统中,MPPT(maximum power point tracking)的控制算法一直是重点研究的课题之一。根据光伏发电的特性[1],在传统算法的基础上提出了一种全新的控制算法——基于dP/de的MPPT算法。从理论推导和控制算法两方面验证了这种算法在控制精度和控制速度上均能很好地满足需要。

In the photovoltaic power generation system,an MPPT control algorithm is one of the key research topics.According to the characteristics of photovoltaic power generation system,based on the traditional algorithm,a new control algorithm based on dP/de of the MPPT algorithm was proposed.The algorithm could well meet the needs of control precision and control speed from the theory and control algorithm.
