Query: Online smart charging algorithm with asynchronous electric vehicles
  demand   The increasing penetration of Electric Vehicles (EVs) and renewable energies
into the grid necessitates tools to smooth the demand curve. To this end, this
paper suggests an EV charging scheduling algorithm and a smart charging price.
As EVs arrive at the charging station and leave at different times, the
operator of the station applies at each EV arrival an online scheduling
algorithm based on the concept of "water filling. The EV charging price is
guaranteed at their arrival and defined as a function of the online algorithm's
output, following the idea of locational marginal pricing. A numerical
comparison with the offline version of the algorithm -- in which the operator
knows in advance all future arrival and departure times -- shows the efficiency
of the suggested online scheduling algorithm.
