Abstract: In order to solve the computational bottleneck of centralized and large-scale computing systems, improve the response speed and reliability of electric power simulation, and make full use of idle computing resources, a peer-to-peer(P2P) based computing platform for power system simulation was built. The feasibility of the integration of power system simulation with P2P technology was analyzed. By using the hybrid P2P structure, an overall architecture of simulation platform was designed. According to the specific requirements of electric power simulation platform, a P2P communication protocol was stipulated and its syntax and semantics were analyzed in detail. Moreover, a distributed storage system based on P2P structure was studied, which can be applied to the simulation platform with PSD-BPA program. Experimental results show that the platform has a greater superiority in solving large-scale computing problems, and has a broad range of application prospects.

Key words: power system simulation, hybrid P2P structure, protocol analysis, distributed storage, power flow calculation
