Performance Analysis of a V2G Brokering Agent

Abstract:

This paper first presents a brokering architecture for a vehicle-to-grid electricity trades between electric vehicles and a microgrid, and then measures its performance, particularly focusing on the stay time, which significantly affects the scheduling flexibility. The brokering service matches demand and supply on battery-stored energy, traversing the search space to find an energy allocation for each time slot. The slot-by-slot schedule, generated from the two-way interaction protocol, coordinates the arrival time of each seller at the microgrid, achieving temporal and spatial power load shift. The performance measurement based on a prototype implementation analyzes the effect on the lacking and surplus energy, the demand meet ratio, and the effective consumption ratio. The experiment result shows that the brokering scheme can fully take advantage of enhanced flexibility in placing available energy on the time slots, reducing the lacking amount by up to 38.4 % as well as enhancing the consumption ratio by up to 27 % for the given parameter set.
