摘要

本文采用粒子群算法和微扰观测技术求解太阳能光伏板在不同大气条件下的最佳工作参数。确定直流/直流变换器为获得最大输出功率所应开关的端子电压、电流和相应的占空比。在MATLAB中对DSP210太阳能电池板的最大功率点跟踪进行了仿真。结果表明,基于粒子群优化的算法能够在全范围的太阳数据(辐照度和温度)内跟踪到最大功率点,并具有较高的转换性能。

PSO and P&O based MPPT technique for SPV panel under varying atmospheric conditions
This paper presents Particle Swarm Optimization and Perturbation & Observation techniques to find the optimum operating parameters of a solar photovoltaic panel under varying atmospheric conditions. The terminal voltage, current and corresponding duty-cycle, at which the DC/DC converter should be switched to obtain maximum power output, are determined. Simulation of maximum power point tracking of a DSP210 solar panel is done, using both methods, in MATLAB. It is observed from the results that the particle swarm optimization based algorithm can track the maximum power point for the whole range of solar data (irradiance and temperature) and has high conversion performance.
