动态过网费分摊对CDA交易机制下本地市场点对点能源交易影响研究OA

To address the issue of distribution network cost recovery under the peer-to-peer(P2P)energy trading model and to ensure fairness among prosumers participating in market transactions,this paper investigates the impact of dynamic network tariff allocation on multi-prosumer P2P energy trading based on the continuous double auction(CDA)mechanism.The dynamic network tariff is divided into a basic usage fee and a topology-related charge.A quantitative model for the basic usage fee is proposed,incorporating voltage deviation adjustment costs,network loss costs,and concession right loss costs.Meanwhile,a network topology cost assessment model is constructed using the electrical distance matrix to determine the portion of transmission fees related to grid structure.An enhanced zero-information bidding improvement strategy is proposed considering the dynamic network tariff,along with a model predictive control-based quantity bidding strategy to achieve efficient energy transaction matching.Simulation analysis is conducted on an improved 11-node distribution network.The results show that incorporating network tariffs not only increases prosumer trading volumes but also satisfies the requirement for grid investment cost recovery.
