The technique of photovoltaic grid-connected inverter has become the leading method for solar generator system. However, it is urgent and very significant to develop new control strategy for photovoltaic grid-connected inverter to improve its stability. In this paper, a new control strategy based on neuroendocrine-immune (NEI) network is proposed for single-phase photovoltaic grid-connected inverter. Two-way hormone regulating mechanism of human NEI system makes various physiological indicators in a highly stable by the carrier of cytokines, hormones and neurotransmitte. Compared with conventional control method, NEI controller has high performance of rejecting the load disturbance, repressing the AC current distortion, reducing the interference of noise, and improving the shape of current wave. Also, it has very well dynamic performance and steady precision. Theoretical analysis and computer simulation results demonstrate that the proposed method has better dynamic performance and steady precision. It should have broad application prospect in photovoltaic grid-connected system.
