摘要
光伏发电系统工作过程易受光照、温度等环境条件的影响,导致系统工作点的偏移,为使系统输出效率最大化,应进行最大功率点跟踪(MPPT)。针对传统扰动观察法跟踪速度慢、功率波动大的问题,提出基于模糊控制的光伏MPPT控制策略。通过搭建Simulink仿真模型,并在相同环境条件下对两种算法进行仿真,结果显示基于模糊控制的光伏MPPT控制策略能快速、平稳地实现光伏MPPT过程。
The working process of photovoltaic power generation system is easily affected by environmental conditions such as light and temperature,resulting in the deviation of system working point.To maximize the system output efficiency,maximum power point tracking(MPPT)shall be carried out.Aiming at the problems of slow tracking speed and large power fluctuation of traditional disturbance observation method,a photovoltaic MPPT control strategy based on fuzzy control is proposed.By building a Simulink simulation model and simulating the two algorithms in the same environment,the results show that the photovoltaic MPPT control strategy based on fuzzy control can achieve the photovoltaic MPPT process quickly and smoothly.
