中文摘要：

光伏电池输出的功率随外界环境条件的变化而变化,通常采用最大功率点跟踪技术以获得最大功率输出。结合无线传感器网络（WSNs）节点的工作方式与光伏系统的特点,提出了一种基于WSNs的光伏系统最大功率点跟踪技术。针对开路电压法的不足,利用WSNs节点的测温工作方式来进行温度补偿。当系统工作在最大功率点附近时,引入阻抗匹配算法,可有效消减光伏输出功率在最大功率点处的振荡现象,从而提高系统效率。仿真结果验证了该方法的可行性和有效性。

英文摘要：

The output power of photovoltaic（PV）battery varies with enviranment,so the maximum power point tracking（MPPT）technique is applied to PV systems to obtain the maximum power output.A MPPT technology combining working mode of wireless sensor networks（WSNs）nodes and character of PV system is proposed,based on WSNs.Temperature measurement working modes of WSNs node is used to compensate temperature for the shortcoming of open-circuit voltage method.The impedance matching algorithm is proposed to reduce the power oscillation around maximum power point（MPP）.The simulation results demonstrate the feasibility and effectiveness of the method.
