| 摘 要： | 光伏阵列的输出特性受光照强度影响很大，在弱光下光伏电池的最大功率点跟踪控制算法无法达到蓄电池的充电要求。为了最大限度利用光伏阵歹tl的输出功率，采用超级电容减小光照变化对蓄电池充电的影响。针对独立光伏发电系统的特点，设计了一种有源式混合储能方案，在保证光伏电池获得最大功率跟踪的同时，也能满足蓄电池的充电要求，建立的Simulink／MATLAB仿真模型验证了该设计方案的有效性。

| Abstract: | The output characteristics of photovoltaic array is influenced by the incident radiant intensity.Especially in the weak sunlight the maximum power point trace strategy can’t match the battery’s charging requirement.In order to maximize the output power of PV,the method using supper capacitors is proposed to reduce the influence of charging conditions caused by sunlight variation.Based on the character of stand-alone PV system,an active hybrid storage scheme is designed.The scehem can assure the maximum power point tracing of photovoltaic panels and meet the batteries charging requirements at the same time.The simulation model in Simulink/MATLAB is created and the simulation results verifies the feasibility of the system. |
