Peer-to-peer transaction model for prosumers considering franchise of distribution company

When designing peer-to-peer power transaction mechanism for the distribution system level，it is needed to consider the franchise owned by the distribution company，and effectively compensate the invest⁃ ment and operation costs of infrastructure owners of the distribution system by designing appropriate network charging mode. A peer-to-peer transaction model for prosumers considering the franchise of distribution company is proposed. Based on the Stackelberg interaction relationship between distribution company and prosumer，a bi-level game model of network fee pricing based on electrical distance is established，the upper level is a decision-making model of network fee price with the maximum income of distribution company as the object，while the lower level is an optimal dispatch model of prosumers considering network fee. The bi-level game model is transformed into a single level mixed-integer programming problem based on Karush-Kuhn-Tucker（KKT） condition，and then the network fee price is obtained. The alternating direction method of multipliers is used to solve the peer-to-peer real-time transaction power quantity and transaction price of prosumers. The simulative results of IEEE 33-bus distribution system verify that the proposed model can guarantee the benefits of all prosumers on the basis of ensuring the secure operation of distribution system，and can reasonably compensate the income loss caused by giving up a part of franchise of distribu⁃ tion company. © 2023 Electric Power Automation Equipment Press.
