摘要
基于光伏电池工程的数学模型,分析了温度及光照强度对光伏电池输出特性的影响,采用扰动观察和模糊控制2种方法,验证了光伏系统最大功率跟踪的可行性,分析并比较了最大功率跟踪的P-U仿真曲线,结果表明采用模糊控制方法时系统在到达最大功率点处稳定性较好.
Based on simulation model of photovoltaic cell,effects of temperature and light intensity on the output charac-teristics of photovoltaic batteries are analyzed.Perturbation observation algorithm and fuzzy control are used to check the feasibility in maximum power point tracking of photovoltaic system.The simulation P-U curves of maximum power point tracking are analyzed and compared.The results show that the adoption of fuzzy control can achieve better stability in maximum power point.
