光伏电池阵列输出功率受光照强度和温度变化的影响，因此最大功率点跟踪（MPPT）技术广泛应用于光伏系统中。在所有最大功率点(MPP)控制策略中，扰动观察（P&O）MPPT算法因易实现被广泛应用，然而它的缺点是在稳定工作状态下工作点通过MPP 时会导致能量振荡损耗，并且在光照强度或温度发生突变时表现较差的动态响应。在本文中，提出一种改进型变步长扰动观察MPPT 算法，此方法依据工作点动态调整步长变化，与传统固定步长方法比较，本文提出的方法(Photovoltaic array output power is affected by light intensity and temperature change, so the maximum power point tracking (MPPT) technique is widely used in light volt system.In all of the maximum power point (MPP) control strategy, the disturbance observation (P&O) MPPT algorithm is widely used because of easy to implement, but its drawback is that under the steady working state working point by MPP will cause energy loss of oscillation, and the mutations in poor light intensity and temperature of dynamic response.In this article, the paper puts forward a modified variable step disturbance observation MPPT algorithm, this method is based on the working point dynamic adjustment step change, compared with the traditional fixed step length method, the proposed approach)
