Modeling And Simulation Of Ship Power System Integration Of Renewable Energy

Due to the shortage of traditional fuel consumption in recent years and the pollution to the environment,on which people almost all countries of the world demand for energy in the research and exploration,scientists trying to protect and save the traditional fuel and make there best shot to the development of renewable energy.The renewable energy,due to the outstanding performance of the solar energy,PV system has received the world wide attention and research.While using the solar power system to ship voyage,we can effectively reduce the traditional ship's fuel consumption and emissions of pollutants.However,due to extreme sea conditions and ship swaying,it can make a new great influence on the output of the PV system,therefore,we need to make and run the ship power system modeling and simulation analysis,we use this way to simulate the influence of various conditions on the system,we can also find the factors affecting the operation of ship power system stability and to analyze and solve.In this paper,we use the ideas of modularization,on the basis of "high technology of ship project",to set up photovoltaic power generation system,three parts of diesel engine power generation system and flywheel energy storage system and its combination model,form a complete solar power generation system of the ship.This article mainly aims at is to contain the flywheel energy storage system of solar ship power system,to analyze and set up corresponding module.In this paper,the principle of the first part of the traditional Marine power system is studied,based on PSCAD electric power simulation software,the complete build the corresponding module.The synchronous generator and its excitation system is analyzed,and synchronous motor model is established under the simulation software;Then on diesel engine and the corresponding governing system,the induction motor,such as module was analyzed and the corresponding model can be established.In the second part of photovoltaic(PV)power generation system we also studied and analyzed the basic principle and concept of the PV system module,such as batteries,Boost circuit part and maximum power tracking(MPPT)control part,relatively complete PSCAD simulation software of the simulation model is established.The third part mainly consists of the flywheel energy storage system(FESS)solar ship power system modeling and simulation analysis: the first detailed illustrates the principle of flywheel energy storage system,and established the mathematical model,set the flywheel charging and discharging control strategy,and finally verified by using simulation software.The fourth part will contain FESS photovoltaic system incorporated into the ship power system,using simulation experiment platform,the introduction of the flywheel energy storage system are analyzed before and after the ship power system voltage and frequency change,such as to verify the flywheel energy storage system smooth power and voltage.In this paper,the fifth part using ship simulation platform of laboratory building,into the probability calculation,mutation and load simulation of ship rocking,illumination changes,etc.,calculation of ship in different light intensity received by the sea route,studied the transient characteristics of the vessel,before and after the introduction of FESS to verify the feasibility and accuracy of the flywheel energy storage system.Finally,using the particle swarm optimization(PSO),energy storage capacity of FESS and optimized matching between PV array output power,save the expenses.
