The Evaluation Of Technical And Economic Of Electric Vehicle Charge For Electricity Network Planning

According to the development pattern of the world’s energy supply and demand, electric vehicles as an important part of the new energy industry, has been drawing concerns around the world, which has become an inevitable choice for the future of the global automotive industry as a symbol of transformation. To develop electric cars, electric vehicle charging facilities for electric cars is the foundation. Establishment of a perfect electric vehicle in electric facilities service network can widespread the application of electric vehicles.This paper focuses on the technical and economic evaluation indicator of charging for electricity network planning, and makes the comprehensive technical and economic evaluation for the planning by subjective weighting method, so that Service providers can choose the best solutions from multiple planning scenarios.Firstly, the paper proposes the status and significance of the subject research, and analyses the factors that influence the charging for electric network planning evaluation. Then the paper presents the forecasting method of the future number of electric cars and the algorithm of electricity demand for electric vehicles, analyses service capabilities of single station and electricity network development mode, and makes planning schemes of different network development models by demand forecasting. The paper studies technical evaluation factors for electricity network planning making charging for electric network service radius and electric service capabilities as a major technical evaluation. The charging for electricity network planning economic evaluation model is developed. Finally, the thesis makes the comprehensive technical and economic evaluation for network planning and provides an optimal planning method by coordinating the techniques and economic objectives.In this paper, flat and three-dimensional planning are formulated as a instance in a city, and then the evaluation findings can be made through evaluation model for calculation of the two programs and examples analysis. The service provider can select the optimal planning by adjusting the planning parameters neatly.
