Coalition game theoretic P2P trading in a distribution network integrity-ensured local energy market

This paper presents a peer-to-peer (P2P) trading-enabled local energy market (LEM) mechanism and analyses it in the Australian market context to verify its feasibility. To do so, a coalition game theoretic-model is adopted to model the mutual trading interactions between participating purchasers and sellers in the LEM, in which energy is purchased/sold at a rate lower/higher than the business-as-usual purchase/sell price while the margin of the LEM operator is locked on. Further, both purchased and sold energy quantities are also decided on following the import, export, voltage, and line flow constraints, respectively, prescribed for the P2P trading in the LEM. The properties of the proposed coalition game are examined, and the beneficial aspects and stability of the structured P2P coalition…
