  Increasing participation of prosumers in the electricity grid calls for
efficient operational strategies for utilizing the flexibility offered by
Distributed Energy Resources (DER) to match supply and demand. This paper
investigates the coordination performance of a recently proposed coordination
scheme for deferrable loads: Forecast Mediated Market Based Control (F-MBC).
Enhancements are made to the simulation setup to enable an analysis of
performance in realistic scenarios, with heterogeneous loads and an open-ended
simulation horizon. Operational scenarios were formulated to showcase the
ability of F-MBC to schedule heterogeneous populations of deferrable loads with
dynamic load profiles, supported by a mix of renewable and flexible generation.
Availability patterns of devices were generated to take into account varying
user preferences. Simulation results indicate that F-MBC was able to achieve
good distributed scheduling performance for devices with a high initial power
consumption. However, performance for devices with low initial power
consumption has been found to be less satisfactory. Several directions for
further improvement of the F-MBC scheme and its applications are identified.
