Research on Measurement of Electric Vehicle Charging Load Based on Markov Chain Theory
The measurement of electric vehicle charging load is an important basis for electric vehicle charging configuration planning.However,the current methods have low measurement accuracy,low confidence level of measurement results,high MPE,and cannot achieve the expected measurement effect.Therefore,a research on electric vehicle charging load measurement based on Markov chain theory is proposed.Using Markov chain theory to express the charging and travel process of electric vehicles,describing the residual state of charge transfer process of the vehicle,and analyzing the charging load demand of electric vehicles based on the state of charge transfer process at different time periods,measuring the charging load of electric vehicles,thus achieving the measurement of electric vehicle charging load based on Markov chain theory.Experimental results have shown that the confidence level of the measurement results of the design method is above 96%,and the MPE does not exceed 1%,which can achieve accurate measurement of the charging load of electric vehicles.
