  A novel decentralized peer-to-peer-to-grid (P2P2G) trading mechanism
considering distribution network integrity is proposed. In order to direct
prosumers' peer-to-peer (P2P) trading behavior to be grid-friendly, the
proposed method incorporates Dynamic Operating Envelopes (DOEs) into the
existing P2P2G trading. Moreover, DOEs are determined through negotiations
between the distribution system operator (DSO) and prosumers alongside the
process of P2P trading, avoiding compromising prosumers' privacy and network
parameters leakage. To reduce communication costs during P2P trading, a variant
of the alternating direction method of multipliers (ADMM), i.e.,
communication-censored ADMM (COCA) is used to solve the P2P2G trading problem.
Finally, the DOE price is shown to be comprised of several economically
interpretable components. Simulations validate the effectiveness of the
proposed mechanism.
