Study on Peer-to-Peer trading mechanism in local distribution network

The rapid growth of distributed photovoltaic brings great threat to the safe operation of power system. Flexible resources can adjust the local power balance, but there is no corresponding policy in China to encourage flexible resources to participate in power system operation. At present, China is promoting the marketization development of distributed power generation. Therefore, this paper proposes to build a P2P energy market in the local network with distributed photovoltaic. Trading mechanism can encourage users to schedule flexible resources reasonably. It can improve the operating state of the system and increase the photovoltaic accommodation rate. The MMR pricing method was used to allocate benefits within the market. The results showed that the P2P energy market was able to promote prosumers to use flexible resources and increase the hosting capacity of distributed photovoltaic power stations. At the same time, market participants improved economic benefits.
