摘　　要：针对建筑光伏(PV)发电和大规模集中式PV发电中多条升压支路并联的情况,提出自适应线性调整器重启粒子群算法优化(PSO)法,通过选择合适的开关管导通时间,使各光伏阵列运行于各自的最大功率点,从而实现多路功率最优控制,并且克服了传统最大功率点跟踪(MPPT)算法在复杂环境中易陷入局部最大功率点而失效的问题。最后,通过实验验证了所提控制策略的有效性。For the case of many Boost branches parallel connecting on the building photovohaic （PV） power generation and large-scale centralized PV system, an adaptive linear regulator restarting particle swarm optimization （PSO） algorithm is proposed.By selecting the appropriate switch conduction time,the respective PV array is operating in the respective maximum power point, in order to achieve optimal multi-channel power control and overcome the traditional maximum power point tracking（MPPT） algorithm easily fall into the local maximum power point in complex environm- ents.Finally, the effectiveness of the proposed control strategy is verified by experimental results.
