Research on Modeling and Simulation of Battery Swap Station Based on Discrete Event

This paper builds a model for the operation of battery swap stations based on discrete event and build corresponding simulation system for optimized configuration of battery swap stations. The results showed that both the quantity of the robots and the utilization of source were important factors to ensure the optimal configuration of battery swap stations in the premise of supposing the traffic flow and the higher utilization of source, the higher operation efficiency in the premise of the normal operation of battery swap stations. Introduction With the development of world economy, ecological environment worsening and the contradiction between the growing demand for energy is increasingly obvious. And the development of electric vehicles has great influence in improving energy efficiency and cutting CO2 emissions [1-4]. In recent years, scholars at home and abroad according to the different characteristics of electrical changing station constructed many kinds of models. Liu Yujiao and other colleagues[5] reduce the electric car in plant operation as much as possible in the case of meeting the demand of electric vehicles in electricity and establish the mathematical model which makes expectation and variance of the cost as the objective function; Karbasioun M M and other colleagues[6] established markov decision process model under the premise of that charging vehicles obey the poison distribution and the charging demand are independent of each other; Wen-qi tian and other colleagues[7] according to the characteristics of the electric vehicle in plant, make charging power in different power plant each time as control object, establish the mathematical model of charging order scheduling policy for three kinds of objective function of Smooth the load fluctuation, poor peak valley, load rate,. In the simulation, Zhang Shu and other colleagues[8] introduced in power plant electric vehicles in traditional unit combination problem, established the new model of in power plant and power network interactive unit combination and called on the software of CPLEX to solve problems based on Matlab; Liu Nian and other colleagues[9] through the research of the active control strategy of power plant operation In the case of distribution network fault, built the simulation model of feeder automation based on PSCAD software and simulated analyze the influence for the feeder automation when power plants are using active control strategy. Due to countries actively promote the development of electric buses, electric buses as infrastructure are used in a big number. Therefore, this paper will regard the operation of the electric bus in power plant as the research object. In view of the problem of optimal operation in power plant, considering the in plant operation more accord with the characteristics of discrete event system and the characteristics of the randomness, we proposed discrete event modeling method based on AnyLogic software platform with the simulation system of form a complete set of and find out the optimal configuration under the certain conditions in power station.

The authors Published by Atlantis Press 1926 to stay in power electric cars as the "real" in the system, fully charged batteries as "resource" in the system, the charge in the electric process as a "service" in the system and all electric cars with no response as the "queue" in the system. The operating model of electric cars in power station is mainly composed of input and output variables, operation and some basic parameters [10]. The basic flow chart shown in Figure 1.
