A New Management Method for Reliable Peer-to-Peer Energy Sharing in Power Distribution Systems

Abstract

The current expansion of renewable energies, restructuring in power systems, and high tendency to preserve the privacy of energy customers could lead to significant changes in distribution systems. Accordingly, studies on local markets have introduced a suitable framework for energy trading known as the Peer-to-Peer (P2P) market in distribution systems. Several research works have been done on the P2P market modeling and optimization in recent years. This paper aims to develop an appropriate P2P market framework in which the distribution system operator (DSO) can rerun the P2P market and maneuver in the case of the network failure. Respectively, in case of any grid failure, the P2P market can be adjusted according to new conditions of the grid, which is not studied in the previously developed methodologies. In addition to enabling the P2P framework to be usable when a network failure occurs in the system, this paper proposes a reliability cost model associated with participated sellers in the P2P market, which enables buyers to consider the reliability of the sellers in their decisions. Consequently, the developed scheme facilitates the reliable operation of distribution systems in a distributed manner. Finally, the developed structure is simulated on a 33-bus test system to analyze its effectiveness in operating the system.
