Abstract
Environmental concerns over the production of
greenhouse gas have led to the development of environmental
friendly transportation such as electric vehicle (EV). As the number
of EVs is increasing day by day, it will have a great impact on grid
operation and electricity market. Significant amount of EV
charging during peak hour will cause branch congestions and low
voltage. Moreover, high penetration of EVs plays an important role
in altering electricity price. Thus, optimal scheduling of EVs
charging is inevitable from the perspective of both system reliability
and market. Load aggregators can combine the capacities of many
EVs to participate in wholesale energy market. In this paper,
optimal dispatch algorithm of EVs is developed and tested on a
system consisting 1000 EVs. The advantage of the algorithm is that
it requires less number of communication signals and less expensive
infrastructure. EVs are turned on and turned off in binary fashion
based on priority to follow the regulation signal.
