北京理工大学珠海学院2016届本科生毕业设计Research on Wind,Solar,Diesel and Storage Microgrid SystemAbstractWith the development of human society,the destruction of human beings to nature ismore and more serious,relying too much on fossil energy such as coal and oil to supplyenergy,various environmental problems are gradually emerging,and people are beginning topay more attention to environmental problems.The power generation of renewable energysuch as wind energy and light energy is getting more and more attention and application.Micro-grid is a small-scale power generation and distribution system,which iscomposed of distributed power module,energy storage module,load module and monitoringand protection module.It is also called micro-grid.Due to the lack of resources and airpollution,the new energy power generation technology using wind energy and solar energyhas become the goal of scientific research.In order to realize the flexibility and efficiency ofthe distributed power and solve various different problems of the grid connection of thedistributed power,we propose a wind and diesel micro grid system.The wind and dieselmicro grid system includes solar power module,wind power module,diesel generator powermodule,energy storage device module,load module and micro grid connecting them.Inorder to promote the close connection between distributed power generation and renewablenew energy and realize the reliability of various load power supply,we develop,design andexpand the distributed power supply to find a reasonable maintenance mode.Micro-gridconnects the traditional grid to the smart grid.The wind and diesel micro grid system can effectively solve the problem oflong-distance power supply which can not be reached by the ordinary grid.Although it hasmany advantages,it does not support the backup energy storage of the large grid.At the sametime,the power supply of wind and solar energy is not stable,with intermittent volatility,which is greatly affected by the natural environment factors.Therefore,the reasonableconfiguration of the micro grid has also been studied Emphasis.The reasonable configurationof micro-grid reduces the construction cost and generation cost,improves the reliability ofpower supply,reduces the power loss between loads,and plays an important role in theoptimization of micro-grid.At the beginning,the purpose and significance of micro-grid system,its applicationfields,development trends and prospects at home and abroad,and the main problems to besolved in this paper are studied.Secondly,the principles of wind power generation,photovoltaic power generation anddiesel engine power generation are discussed,and then the structure of the micro grid system
