摘要

围绕新能源发电在大型远洋船舶上的大规模接入问题,研究了基于太阳能发电的客货滚装船光伏阵列布局、拓扑结构及最大功率点跟踪(MPPT)模型与算法.结合船舶航行环境与船体结构特点,设计了大规模光伏阵列的船体布局及拓扑结构,建立了以大规模全局优化(LSGO)问题为描述形式的船体区域级MPPT数学模型.此外,提出一种基于环形拓扑的多参考向量协同进化粒子群算法(CCPSO-MR),并成功应用于船用大规模光伏阵列MPPT控制.仿真实验表明,针对LSGO问题的实时求解,CCPSO-MR算法在收敛速度、精度等方面显著优于各主流算法.基于所提阵列结构及MPPT算法,光伏系统能够在客货滚装船上实现大规模接入,并在各类复杂光照航行环境下具有良好的MPPT性能.%To introduce the new energy power generation into large ocean-going ship,the topological structure as well as the MPPT model and control algorithm of large-scale photovoltaic array in ro-ro ship was studied.By considering the navigation environment and structural features of large ro-ro ship,the topological structure of large-scale photovoltaic array was designed,and its hull-part-level MPPT model described as the LSGO was also built.Additionally,a cooperatively coevolving particle swarm optimization based on multi-context vectors and ring topological structure (CCPSO-MR) was proposed and applied to the MPPT control of the ship's large-scale photovoltaic array.Simulation results show that the CCPSO-MR performs better than some famous algorithms in convergence speed and accuracy on solving the LSGOproblems.With the utilization of the proposed structure and MPPT algorithm,the large-scale photovoltaic system can be introduced into the ocean-going ro-ro ship successfully and works well under complex environmental conditions.
