A Unique Approach to Demand Side Management of Electric Vehicle Charging for Developing Countries

摘要

Increased penetration of electric vehicles (EVs) can lead to uncoordinated charging which can result in electrical distribution network overloads and possibly outages as well as increased peak demands. This can particularly occur in power systems with minimal and insufficient demand side management schemes where there is no time of use (TOU) tariffs. Such is usually characteristic of small Caribbean island power systems and their numerous distinctive policy, technical and infrastructural challenges. This manuscript documents a unique approach for EV charging (AC level 1 and 2) in Trinidad and Tobago with application to other developing countries. A prototype device is designed and developed for connection to the EV that allows remote (IEEE 802.11 Standard) modification by the electrical utility of the pilot control signal of the J1772 charger.
