Prosumer Markets: A Unified Formulation

The increasing share of more proactive actors in the electricity market supports the proposal of novel schemes to accommodate a more decentralized paradigm to power system and electricity market operation. The resulting prosumer markets may be identified as belonging to various classes such as prosumer grid integration, peer-to-peer models and prosumer community groups. We show here that they all can be modelled within a unified peer-to-peer market model but with different communication structures. Consequently, we profit of this unified formulation to compare these structures in terms of efficiency and convergence speed, as well as by generally looking at the effect of sparsification of those communication structures on market outcomes and convergence speed. The open-source simulation platform developed for that purpose may be readily used by others to study and analyze prosumer markets.
