摘要
基于光伏阵列的物理机制,结合光伏电池的等效电路,建立了数学模型,在MATLAB/Simulink仿真环境下,建立了可以模拟恒定条件、光强突变、温度突变条件下仿真的独立光伏系统模型,将PSO算法改进为Geese-HPSO算法,进行基于光伏阵列MPPT控制的独立光伏系统仿真,同时将仿真结果与扰动观察法进行对比,验证了Geese-HPSO算法跟踪最大功率点的快速性与准确性。
Based on the physical mechanism of photovoltaic array, combined with the equivalent circuit of pho-tovoltaic cells, the mathematical model is built. In MATLAB/Simulink, different simulation models are developedfor the independent photovoltaic system which can be imitated in the situations of a constant condition, light intensi-ty mutation and temperature mutation. PSO algorithm is improved to Geese-HPSO algorithm. The independent pho-tovoltaic system based on photovoltaic array maximum power point tracking（MPPT） control is simulated and thesimulation results are compared with the disturbance observation method. The quickness and accuracy of the im-proved Geese-HPSO algorithm to track the maximum power point are testified.
