On distributed energy routing protocols in the smart grid

The smart grid shall integrate the distributed energy resources and intelligently transmit energy to meet the requests from users. How to fully utilize the distributed energy resources and minimize the energy transmission overhead becomes critical in the smart grid. In this paper, we tend to address this issue and develop the distributed energy routing protocols for the smart grid. In particular, we first develop the Global Optimal Energy Routing Protocol (GOER), which efficiently distributes energy with minimum transmission overhead. Considering that the computation overhead of GOER limits its use in large-scale grids, we then develop the Local Optimal Energy Routing Protocol (LOER) for large-scale grids. The basic idea of LOER is to divide the grid into multiple regions and adopt a multiple layer optimal strategy to reduce the energy distribution overhead while preserving the low computation overhead. Through extensive theoretical analysis and simulation experiments, our data shows that our developed protocols can provide higher energy distribution efficiency in comparison with the other protocols.
