Analysis of Energy Consumption at Public Charging Stations, a Nebraska Case Study

摘要

Plug-in Electric Vehicle (PEV) charging stations can have a significant influence on the electric grid and its reliability. In order to evaluate the influence of rapid penetration of PEVs and their charging infrastructure on the electric grid, and assess their potential benefits to the future micro-grid, statistical analysis of PEV charging behavior is essential for planning as well as running public charging stations in different areas. In this paper, 27,481 charging sessions from public charging stations in the state of Nebraska are analyzed to determine the relationship between energy consumption, time, and location of charging. A multinomial logistic regression model is presented to aid utility companies in anticipating the charging demand of PEV users, as well as the impact on the electric grid at increasing PEV penetration rates.
