| Summary: | Electrification of the transportation segment has
long been seen as a promising solution to reduce oil dependency
and its environmental impacts. Electric Vehicles (EVs) can also
be used as distributed energy resources providing ancillary
services to the grid through Vehicle-to-grid (V2G). Incentives
through V2G can lead to reduced EV ownership cost, thus
increasing their acceptance and overall penetration. However,
with high current battery prices and increased battery wear due
to more frequent charging and discharging during V2G
operations, it becomes economically challenging in realizing a
profitable business model. This paper presents an economic
analysis of various V2G offerings in consideration of market
prices and battery wear cost. Aggregate Power Capacity, from a
fleet of EVs is realized by modeling their driving pattern using
trip chaining based on data from survey conducted, employment
pattern and vehicular statistics. Battery life cycle is analyzed, for
achievable cycle counts and net energy transferrable, operating
to various depths of discharge (DoD) values. Economic analysis is
performed using Singapore data. |
