Prosumers Peer-to-Peer Transaction Decision Considering Network Constraints

With a large number of distributed renewable energies, distributed energy storage and controllable devices connected to end users, the traditional electricity consumers have been transformed into prosumers with dual characteristics of electricity production and consumption, which can carry out flexible peer-to-peer transactions anytime and anywhere. Firstly, this paper puts forward the framework of prosumers peer-to-peer transaction. Secondly, a peer-to-peer transaction model is constructed, which takes the constraints of energy conservation, energy storage charge and discharge, and interactive power into account. And the aim is maximizing the interests of prosumers. Then, considering the influence of distribution network physical constraints on the transaction results, the transmission power of the transmission line is calculated by the power transfer distribution factor (PTDF) to adjust the transaction. Finally, taking the distribution network with IEEE15 nodes to study the case, and analyzing the influence of distribution network physical constraints to the prosumers peer-to-peer transaction.
