Method for selecting and optimizing typical scenes in electric automobile charging facility planning

Abstract

The invention discloses a method for selecting and optimizing typical scenes in electric automobile charging facility planning, which comprises the steps of building an improved Floyd algorithm based electric automobile locating and sizing model; building a charging facility planning scheme evaluation system; aggregating electric automobile charging demands from a time dimension and a space dimension based on a K-means clustering algorithm, and screening or construction a typical day; solving a corresponding charging facility planning scheme; and evaluating the construction of the typical day according to the charging facility planning scheme evaluation system. According to the invention, traffic factors such as road congestion are considered, so that actual situations are reflected more comprehensively. The most representative one or more typical days can be acquired according to the time-space two-dimension K-means clustering based planning typical day construction method, typical charging demand scenes are reflected, and the calculation amount of a planning problem is significantly. Through controlling the number of clustering centers, evaluation indexes of the planning scheme can be improved, and the satisfaction degree of users is improved.

Description

technical field [0001] The invention relates to electric vehicle charging facilities, in particular to a method for selecting and optimizing typical scenes of electric vehicle charging facility planning. Background technique [0002] Traditional electric vehicles use petroleum as fuel, consume a large amount of fossil energy, and exacerbate the global energy crisis, and the exhaust gas contains a large amount of carbon dioxide and harmful gases, which has brought about a series of environmental problems such as climate warming and urban smog. The number of cars is growing rapidly. In 2015, the number of cars in the world has reached 1.12 billion. The energy and environmental problems accompanying it are becoming more and more serious. Electric vehicles use electric motors instead of internal combustion engines, and use electric energy as their power source, which greatly improves energy utilization efficiency and reduces emissions of greenhouse gases and harmful gases in cit...

Problems solved by technology

[0004] However, the current construction of electric vehicle charging and discharging facilities in my country has just started, and the relevant planning and construction theories still lag behind the needs of actual construction

The solution to the planning problem of electric vehicle charging facilities needs to be based on certain typical days or typical scenarios. The selection of typical scenarios will significantly affect the planning results, but there are few related studies at present.
