Distributed Network-Constrained P2P Community-Based Market for Distribution Networks

Energy communities have been designed to empower consumers while maximizing the self-consumption of local renewable energy sources (RESs). Their presence in distribution systems can result strong modifications operation and management such systems, moving from a centralized distributed one. In this scope, work proposes community-based market that aims at minimizing costs each community member, accounting for technical network constraints. The alternating direction method multipliers (ADMM) is adopted distribute market, preserve, as much possible, privacy prosumers’ assets, production, demand. proposed tested on 10-bus medium voltage radial network, which node contains large prosumer, relaxed branch flow model optimization problem. framework modeled fashion. Market clearing day-ahead basis carried out taking into account actual exchanges, generation uncertain. comparison between ADMM approach shows an 0.098% error nodes’ voltages. integrated OPF computational burden increases resolution dispatch problem by about eight times computation time, 200.7 s (without OPF) 1670.2 s. An important conclusion structure guarantees P2P exchanges avoid violation constraints, ensures agents’ still benefit architecture advantages.
