To fully exploit the flexible regulation potential at the distribution side and promote the local consumption of new energy through secure and fair trading of distributed resources,this paper proposes a coordinated regulation strategy for congestion management and network tariff allocation in peer-to-peer(P2P)energy trading with prosumer participation,based on the continuous double auction(CDA)mechanism.To address line flow overloading caused by distributed transactions while considering the network investment cost recovery,a congestion management model based on node marginal price is constructed.To quantify network usage costs arising during transactions,a network tariff calculation model is developed,incorporating both a basic usage fee and a topology-based surcharge.The network tariff is then settled according to the post-congestion-management trading results,and prosumers dynamically update their trading decisions accordingly.Simulation results on an optimized 11-node distribution network show that the proposed strategy effectively increases trading volume among prosumers,enhances system security and economic performance while safeguarding participants'economic benefits,and satisfies the requirement for network investment cost recovery.
