The increasing uptake of distributed energy resources (DERs) in distribution
systems and the rapid advance of technology have established new scenarios in
the operation of low-voltage networks. In particular, recent trends in
cryptocurrencies and blockchain have led to a proliferation of peer-to-peer
(P2P) energy trading schemes, which allow the exchange of energy between the
neighbors without any intervention of a conventional intermediary in the
transactions. Nevertheless, far too little attention has been paid to the
technical constraints of the network under this scenario. A major challenge to
implementing P2P energy trading is that of ensuring that network constraints
are not violated during the energy exchange. This paper proposes a methodology
based on sensitivity analysis to assess the impact of P2P transactions on the
network and to guarantee an exchange of energy that does not violate network
constraints. The proposed method is tested on a typical UK low-voltage network.
The results show that our method ensures that energy is exchanged between users
under the P2P scheme without violating the network constraints, and that users
can still capture the economic benefits of the P2P architecture.
