摘要
在对风光互补能源系统的充电管理和直流输出控制中,由于模糊控制不仅适应性强、鲁棒性好,而且适合风光互补能源的非线性特点,被有效使用。基于模糊控制的风光互补能源系统,在周密考虑了各项因素对蓄电池影响的基础上,通过专家数据完善了模糊规则库,建立合理的模糊充电控制结构;同时,在对系统直流输出的控制中采用Fuzzy/PID控制,结合传统PID控制稳态响应特性好的优势,稳定了直流输出电压。
Fuzzy control gives full play to its strong adaptability and good robustness during coping with the non-linearity characteristic in wind-solar complementation power supply. The fuzzy expert charging manage system, which takes into account the impact of each items for storage battery thoroughly, is established perfectly by the flawless fuzzy rules which is based on the expert data. In the same time, the systemic DC output control combines the traditional PID control which has the best steady state response characteristic with the fuzzy theory to stabilize DC deferent voltage.
