中文摘要:光伏发电已成为新能源发电的主要研究方向,但当外界环境发生突变或由于遮挡使光伏阵列出现阴影时,传统的最大功率点跟踪(MPPT)算法会出现误判或因陷入局部最大功率点等问题而失效。针对这些问题,提出了一种自适应线性调节的粒子群(PSO)算法,并采用一个MPPT控制器同时实现多支路光伏阵列群体MPPT控制。最后,通过仿真验证所提控制策略的有效性。结果表明,自适应线性调节PSO群控方法振荡小,可实时精准跟踪最大功率点,控制电路较为简单,降低系统控制成本。

Control of PV Group MPPT Based on Adaptive Linear PSO
Abstract:Photovoltaic power generation has become the main research direction of new energy power generation, but when the sudden changes in the external environment or due to the barrier to make photovoltaic array in the shadow, the traditional maximum power point tracking (MPPT) algorithm is a miscarriage of justice or lost in local maximum power point and failure. Aiming at these problems, an adaptive linear particle swarm optimization (PSO) algorithm is proposed, and a MPPT controller is used to realize the MPPT control of multi branch PV arrays. Finally, the effectiveness of the proposed control strategy is verified by simulation. The results show that the regulation linear adaptive PSO group control method for small oscillation can be real-time precise tracking of the maximum power point. The control circuit is simple and can reduce the cost of the control system.
