Abstract

Abstract:

The development and applications of electric vehicles have become a strategic option in many countries around the world to address the energy crisis and environmental pollution problems. Extensive applications of plug-in electric vehicles could result in some new problems even challenges to the secure and economic operation of a power system concerned. Given this background， the state-of-the-art and future prospect of power batteries are introduced at first， and the aggregated load characteristics of electric vehicles with their spatial and temporal distributions considered are presented in detail. Then， the impacts of plug-in electric vehicles on the power system especially on the distribution system concerned are outlined. The coordinated interactions between electric vehicles and power systems are next addressed， and some charging and discharging control strategies for electric vehicles are outlined for supporting the secure and economic operation of the power system. Finally， the economic profits of the interactions between electric vehicles and power systems are briefly examined from both the perspective s of the owners of electric vehicles and the power system.

Key words: electric vehicle, power system, power battery, aggregated load characteristics, charging and discharging control
