摘要
最大功率点跟踪技术(MPPT)被广泛用在光伏发电系统中,根据光伏电池的特性,提出一种具有光照环和温度环的新型MPPT控制算法,并且优化了系统的启动性能。Matlab仿真结果表明该方法能够快速启动,同时当外界大气环境剧烈变化的时候,能够快速、准确地跟踪光伏阵列的最大功率点,并且减小最大功率点处的振荡,减小功率损失。
Maximum power point tracking （MPPT） technology is widely used in photovoltaic power generation system. According to the characteristics of photovoltaic battery, a new MPPT control algorithm with insolation loop and temperature loop was proposed, optimizing the startup performance of the system. The Matlab simulation results show that the method can quickly start, and quickly and accurately tracking the PV array maximum power point, reducing the oscillation at the maximum power point and the power losses in rapidly changing illumination conditions.
