A Peer-to-Peer Trading Mechanism of Virtual Power Plant Considering Contact Line Constraints

The article focuses on the study of virtual power plants (VPP) participating in the electricity market in the region. Based on the traditional centralized trading model, considering the connection between the virtual power plant and the power grid, contact line constraints are added in the trading process to make the trading model closer to reality. Meanwhile, in order to fully protect the interests of the virtual power plant, while considering the contact line constraints, the peer-to-peer (P2P) trading model between aggregators was established to realize the resource synergy within the virtual power plant. Compared with directly processing the transaction results of the centralized transaction model through the way of equal proportion reduction, the mechanism model designed in this paper can make the transaction closer to reality and fully guarantee the interests of the virtual power plant through simulation.
