Peer-to-Peer Electricity Market based on Local Supervision

The active participation of small-scale prosumers and consumers with demand-response capability and renewable resources can be a potential solution to the environmental issues and flexibility-related challenges. A local peer-to-peer market is proposed to exploit the maximum flexibility potential of prosumers. In this local market, network users can trade with each other as well as the grid. The proposed trading model includes two levels to consider both the democracy and the profitability of energy trading. At the first level, the model considers the trading preferences of each player to respect the peers’ choices. The second level matches the rest of the bids and offers of the local buyers and sellers aiming to maximize the social welfare of all of the players participating in the local market. Our proposed local market is implemented for a test system consisting of fifteen residential players, and the results are compared to other trading models through different comparison criteria such as social-welfare of all players and the net cost of each individual player from consuming electricity. Simulation results for the case study demonstrate that the proposed local market model can still be profitable and liquid while respecting the players’ trading preferences and choices.
