A Study On The Application Of P2P In Power Grid

The countrywide power network will be achieved to grid-connected. In order to ensure the safety, stabilization and the real-time state precisely, in which each dispatched centre must communicate and cooperate by some way of the power grid. Such extensive distributed characteristic of interconnected electric network determinates the inevitable trend of distributed system in the development of monitoring system. Grid has the potential to satisfy the demand of monitoring system of interconnected electric network in future, because it integrates the extensive distributed source. However, with the development of grid, the grid model structured via five layers of sandglass has been become a bottleneck in resource integration.P2P(peer-to-peer) is a distributed technology. Both P2P and Grid are complementary from their construction to application. If the advantages of P2P is employed to offset grid's weakness, the bottleneck problem can be resolved effectively by constructing the grid system with P2P mode. Such a system can provide more advance and stronger environment of grid.In this study, all kinds of P2P and grid model are synthesized. A novel architecture, i.e. P2P-Grid model of the power system, is introduced to deal with the bottleneck which exists in resource integration of large-scale power grid, and other performances of grid will be enhanced via P2P technique. Every part of the whole regional interconnected power system belongs to different company with different power marketing mode. So it will be a hot potato for power grid to mutually accomplish the analysis and computation of power network.In this work, a prototype system of power computation grid based on P2P is constructed by JXTA. In order to simulate different parts of the regional interconnected power system, some plats based on a lot of IEEE model are incised, and the corresponding integrative distributed power flow are computed. The simulation result has demonstrated the effectiveness and feasibility of the proposed approach. The compatibility and Transplantation of this model is attempted to discuss.
