  Owing to the decreasing costs of distributed energy resources (DERs) as well
as decarbonization policies, power systems are undergoing a modernization
process. The large deployment of DERs together with internet of things (IoT)
devices provide a platform for peer-to-peer (P2P) energy trading in active
distribution networks. However, P2P energy trading with IoT devices have driven
the grid more vulnerable to cyber-physical threats. To this end, in this paper,
a resilience-oriented P2P energy exchange model is developed considering three
phase unbalanced distribution systems. In addition, various scenarios for
vulnerability assessment of P2P energy exchanges considering adverse prosumers
and consumers, who provide false information regarding the price and quantity
with the goal of maximum financial benefit and system operation disruption, are
considered. Techno-economic survivability analysis against these attacks are
investigated on a IEEE 13-node unbalanced distribution test system. Simulation
results demonstrate that adverse peers can affect the physical operation of
grid, maximize their benefits, and cause financial loss of other agents.
