    摘 要:以離網(wǎng)三相光伏逆變器為研究對象, 選擇電壓電流雙閉環(huán)控制作為其控制策略,針對傳統(tǒng)PI控制參數(shù)難整定、系統(tǒng)變化適應性差的問題,引入了分子動理論優(yōu)化算法來辨識雙閉環(huán)控制器的PI參數(shù),實現(xiàn)動態(tài)優(yōu)化?;贛ATLAB平臺的仿真實驗結(jié)果表明:相比于傳統(tǒng)的PI 控制以及PSO和GA算法兩種智能算法,該算法具有操作簡便、超調(diào)量小、響應快、適應性強等特點;系統(tǒng)輸出的電壓、電流波形呈現(xiàn)良好的正弦特性,總諧波畸變率小,有效改善了逆變器的動態(tài)性能及其輸出電壓的質(zhì)量。

    Abstract: The three-phase photovoltaic inverter is used as the research object and the voltage and current double closed loop control was selected as its control strategy. Aiming at the problem that the traditional PI control parameters were difficult to be adjusted and the system variation was poor, kinetic molecular theory optimization algorithm was introduced to identify the PI parameters of double closed loop controller to realize dynamic optimization. The result of simulation experiment in MATLAB shows that compared with the traditional PI controller, the particle swarm optimization (PSO) and GA algorithms have many advantages, such as simple operation, small overshoot, fast response, strong adaptability and so on. The system output voltage and current waveform has a good sinusoidal characteristic, and the total harmonic distortion (THD) is smaller, which can improve the dynamic performance and the quality of output voltage in inverter effectively.
    Key words: three-phase photovoltaic inverter; double closed loop PI control; kinetic molecular theory optimization algorithm; parameter identification
