To solve the energy crisis and environmental pollution caused by the overuse of traditional fossil fuels such as coal,oil and natural gas.The use of new energy sources such as wind energy,hydropower and solar energy to replace traditional fossil energy to some extent is an important way to solve this problem.Among them,solar energy has the broadest application prospects.Ships are energy-consuming devices.Applying photovoltaic power generation technology to ships to share part of the power generation tasks of diesel generator sets is of great significance for achieving energy-saving and emission reduction of ships.However,due to the influence of sea conditions and weather factors,the output of photovoltaic systems will fluctuate greatly.Therefore,it is necessary to carry out modeling and simulation analysis of the ship power system integrated into the photovoltaic power generation system to obtain various factors that affect the stable operation of the ship power system and analyze and solve them.This article is based on the high-tech shipbuilding research project "(adopts flywheel energy storage technology)solar energy application research on oil tankers" and carries out in-depth exploration of large tankers(VLCC)that integrates energy storage systems and photovoltaic power generation systems.The overall use of modular ideas,the various components of the ship power system modeling and simulation analysis.First,a simulation model of a diesel generator set in a traditional ship power system is constructed.Then the photovoltaic power system is further divided into three parts: the photovoltaic cell part,the energy storage part and the grid-connected inverter,and each part is studied separately.Modeling and simulation of solar photovoltaic power generation systems,three types of energy storage systems(supercapacitor energy storage,battery energy storage,flywheel energy storage)and ship power systems integrated into energy storage and photovoltaic power generation systems in simulation software PSCAD/EMTDC The analysis mainly focuses on the tracking of the maximum power point of PV system components under the change of external environment,the impact of PV power system after being integrated into the ship power system,and the selection of the optimal energy storage method to suppress the power fluctuation of the PV system and optimize the power quality..Study the new type of photovoltaic inverter topology and control strategy to improve the effect of unbalanced output voltage on the output voltage caused by the introduction of unbalanced load on the ship,and use the Matlab/Simulink simulation platform to verify its effect.Finally,combining with the actual engineering,the simulation model of the real ship power system is built in the power simulation software,and the VLCC practical power system design scheme is verified by simulation.Verify that the design plan meets the requirements of various tasks and provide reference for the actual engineering installation of the ship power system.
