Research On Capacity Allocation Of Micro-grid Considering Electric Vehicle

In 21 Century,human beings are facing the problems of energy shortage and environmental pollution.At the same time,China has great potential for the development of new energy resources.Micro grid as an effective organization form of distributed energy,can build “Local area network” by the new energy power’s generation,collection,gathering and sharing as well as micro-grid store energy or electricity consumption,which can promote the use of new energy.Therefore,the combination optimization of electric vehicle charging facilities and micro-grid which is high-level use of new energy sources,it can improve the current situation which electric vehicles rely on the traditional power grid and not fundamentally achieve the goal of energy saving and emission,will be a great significance to the construction and development of new energy sources.In this paper,the main works are as follows:Firstly,based on the background and significance of the topic,this paper expounds the current situation and the main characteristics of the micro grid and the electric vehicle.Summarizing the progress and disadvantages about EV and micro-grid at home and abroad,inducing the main content and structure of research as well.Secondly,based on the existing electric vehicle charging mode,charging facilities and the summary of the charging standards,this paper discussing the integration of electric vehicles used in micro grid,building mathematical model of the distributed power supply model and the output characteristics,studying about charging rules and requirements on various types of electric vehicles to establish electric vehicle load forecasting model.Finally,this paper building double-target configuration model based on the optimization scheduling model about considering demand side response and EV cluster scheduling,the core of DAC and MUL,the constraint of Configuration quantity,DRL and BAL.this paper analyzes the influence of the overall operation of the electric vehicle on the economy,reliability and the utilization of new energy sources of the micro-grid.
