Impact of P2P trading on distributed generation curtailment in constrained distribution networks

The increasing uptake of Distributed Energy Resources and advancement in blockchain technology has led to the growth in interest in the peer-to-peer (P2P) based energy trading. However, there has been a lack of consideration how these trades may affect the network operation, in particular in networks that apply Active Network Management using Last-in-First-out (LIFO) access rules, such as in the UK. This paper presents a novel application of Optimal Power Flow that manages the P2P trading whilst optimising legacy DGs under a LIFO access agreement. Analysis show that under such arrangements, and in combination with autonomous P2P trading, lower priority DGs are vulnerable to excessive curtailment levels.
