- Peer-to-peer energy trading strategies for decentralized residential energy systemsPublication . Borges, Paulo Ricardo Mesquita; Ferreira, Angela P.; Pereira, Maria JoãoThis work investigates peer-to-peer (P2P) energy trading within residential local energy markets (LEMs) assessing how decentralized bilateral matching mechanisms can increase renewable self-consumption, reduce reliance on the upstream grid, and affect distributional and network outcomes. Two bilateral matching strategies are formalized and implemented: a time-varying Supply–Demand Matching strategy (ST1), which privileges temporal complementarity between surplus and deficit, and a time-invariant Distance-Based Matching strategy (ST2), which privileges geographically proximate trades to reduce distribution losses. Both strategies are embedded in a decentralized market-clearing framework solved via the Alternating Direction Method of Multipliers (ADMM) and implemented in Python using CVXPY with the SCS solver. Experiments are conducted on a synthetic community of ten households derived from real household generation and load data, including photovoltaic and wind profiles. Simulation results show that both ST1 and ST2 materially decrease community grid imports and overall procurement costs compared with the baseline, while producing distinct trade-offs. ST1 attains higher adaptability to temporal variability and delivers greater economic savings and improved renewable utilization in scenarios with pronounced intermittency, at the expense of increased computational and coordination complexity and less stable pairing patterns. ST2 yields more stable, locality-constrained exchanges that tend to reduce distribution losses and operational complexity, though with reduced responsiveness to dynamic supply–demand fluctuations. Sensitivity analyses (varying grid tariffs and local generation capacity) indicate that the relative benefits of P2P trading are amplified under higher grid prices and greater local renewable penetration. The findings provide empirical guidance for the design of scalable, equitable, and technically robust P2P mechanisms and inform policy and DSO considerations for integrating local markets into existing distribution systems.
