摘　　要：在一些偏远的港口或码头,市政电网的供电可靠性相对较弱。利用港口的可再生资源,采用光伏发电系统为船舶岸电供能,不仅可以节省码头的运营成本,还可以助力新能源的就地消纳。船舶码头多变的气候环境会导致光伏发电系统输出的电能无法始终保持最大化。若使用传统的最大功率点追踪策略对系统进行跟踪控制,会在过程中产生较大的误差,并且在稳态时会有明显的功率振荡。针对船舶码头光伏发电系统,设计了一种基于tanh函数的改进型扰动观测法,以实现对系统的最大功率点跟踪控制。通过仿真试验,比较了几种传统算法和本文所提出的新型算法的实际运行结果,验证了该新型算法在码头新能源岸电系统中的可行性和有效性。In some remote ports or docks,the reliability of the municipal power grid is relatively weak.By utiliz ing the renewable resources available at the port,photovoltaic power generation systems can provide shore power to ships.This not only saves operational costs for the docks but also promotes the local consumption of renewable energy.The variable climatic conditions at ship docks can cause the photovoltaic system's power output to fail to maintain maximum levels consistently.Using traditional maximum power point tracking(MPPT)strategies to control the system can result in significant errors during the tracking process,and noticeable power oscillations in the steady state.For the photovoltaic power generation system at ship docks,an improved perturb and observe method based on the tanh function is designed to achieve maximum power tracking control.Through simulation experiments,the actual performance of several traditional algorithms and the new algorithm proposed in this paper were compared,verifying the feasibility and effectiveness of the new algorithm in shore power systems at docks.
