Peer-to-peer energy trading framework for residential buildings

2 August, 2024

Scientists in the UK developed a controller for B2B trading platform that considers thermal and visual comfort. Their modeling shows that participating in local energy trading increases the robustness of the control systems in residential microgrids in face of uncertainty in the occupant comfort level.A group of researchers from the United Kingdom has proposed a novel management strategy for building-to-building (B2B) energy trading in residential microgrids (RMGs). The new method incorporates occupant comfort levels and robust trading against uncertainty in occupant usage.

How does it work?

Active buildings (ABs) are connected together through distribution lines. They can exchange energy, money, and information together and with the main grid,” said the scientists. “Under this community market, a controller collects the information from the ABs and incentivizes them to participate in the market by defining the local price signals.
The controller works on three levels. In its inner circle, optimization is conducted for each connected building without considering the B2B function, with the aim of achieving the lowest possible energy bills. Then, those results are used as a reference in the middle layer, which aims to incentivize the local market for lower costs. The third and final level takes into account the uncertainty in the preferences of occupants in terms of both thermal and lighting comfort.

To test their novel management system, the scientist group ran it on a software simulation. The simulation included ten houses clustered into different groups and different home appliances. To evaluate the performances, they created four cases in the software, which were then compared.
