Optimal Operation Strategy of Hydrogen Range Extender Considering Start-stop Times and Energy Conversion Efficiency
摘要
Abstract
Aiming at the problems of frequent start-stop and low energy conversion efficiency of hydrogen range extenders in hydrogen fuel cell driven vehicles,an optimal operation strategy for hydrogen range extenders considering start-stop times and energy conversion efficiency is proposed.Energy flow of a power supply system composed of a hydrogen fuel cell and a power battery is analyzed,and an overall framework for the optimal operation of hydrogen energy range extenders is built.The power-efficiency characteristics of hydrogen fuel cells is analyzed and the interpolation method for using the power-efficiency characteristics in optimal models is presented.Based on average speeds of traffic flow and estimated travel time obtained from navigation system interface,a power curve and travel energy demand prediction method are proposed,and a start-up rule of hydrogen energy range extenders is constructed.An optimal operation model for hydrogen energy range extenders is established.The objective of the optimal operation model consists of two sub-objectives:deviation of the expected terminal state of charge and energy conversion efficiency.The effectiveness of the proposed method is verified through case analysis.The results show that the proposed method can reduce the start-stop times of the hydrogen energy range extender by 37.50%,and increase the energy conversion efficiency of the power supply system by 28.13%.关键词
