Exploiting the Benefits of P2P Energy Exchanges in Resilience Enhancement of Distribution Networks

TL;DR

The paper addresses resilience challenges in distribution networks by enabling peer-to-peer energy exchanges through a network-constrained double auction framework. It introduces a resilience-oriented MRDA-APM that combines Distributional Locational Marginal Pricing (DLMP) with an Average Price Mechanism (APM) to broker fast, fair trades while respecting network constraints, even in islanded emergency operation. A resilience index RI_t based on load served versus load shed is defined and evaluated on a modified 33-node network, showing P2P exchanges can achieve complete load supply during disruptive periods and increase seller revenue, with varying effects on buyers. The approach offers practical benefits for prosumers and consumers and outlines a path toward deploying P2P resilience in distribution systems with constraint checks via sensitivity factors.

Abstract

As the adoption of distributed energy resources grows, power systems are becoming increasingly complex and vulnerable to disruptions, such as natural disasters and cyber-physical threats. Peer-to-peer (P2P) energy markets offer a practical solution to enhance reliability and resilience during power outages while providing monetary and technical benefits to prosumers and consumers. This paper explores the advantages of P2P energy exchanges in active distribution networks using a double auction mechanism, focusing on improving system resilience during outages. Two pricing mechanisms distribution locational marginal price (DLMP) and average price mechanism are used to complement each other in facilitating efficient energy exchange. DLMP serves as a price signal that reflects network conditions and acts as an upper bound for bidding in the P2P market. Meanwhile, prosumers and consumers submit bids in the market and agree on energy transactions based on average transaction prices, ensuring fast matching and fair settlements. Simulation results indicate that during emergency operation modes, DLMP prices increase, leading to higher average transaction prices. Prosumers benefit from increased market clearing prices, while consumers experience uninterrupted electricity supply.
