  4. Abstract:
  5. Emergence of the prosuming phenomenon inspired by environmental and financial incentives has led to a paradigm shift in energy markets and operational conditions of power distribution networks. As a result of this transition, Peer-to-Grid (P2G) and Peer-to-Peer (P2P) energy markets have received a lot of attention in recent years. These markets must prioritize the facilitation of fair and efficient energy trading while considering the preferences of both parties participating in these markets as well as Distribution System Operators (DSOs). In this context, ensuring the viability of the network's physical structure is essential. Without a robust physical structure, the energy trading process and the fulfillment of the parties'commercial obligations would be disrupted due to faults. Our proposed framework involves a fault-resilient energy management system in which P2G and P2P energy transactions are re-arranged based on factors such as the electrical distance of the dynamic physical route swept by P2P and P2G transactions and energy price. The electrical distance between end-users is calculated based on the dynamic configuration of the distribution network, which is adjusted due to the removal of faults and mitigation of emergencies such as line failures. In the developed framework, to reduce the overall operational cost of the community, an energy-sharing coordinator named Market Operator (MO) would then take into account the network configuration optimized by the Network Operator (NO). The obtained framework which joins the Network Re-configuration (NR) problem and the energy transactions re-arrangement problem in a hierarchical manner, is implemented on a 22-bus distribution system to evaluate its effectiveness in decreasing power losses and operational cost of grid-connected energy communities. © 2024
