A power system model with reasonable external network is needed for new energy management system. Network reconstructing ensures the validity of dynamic security assessment done in the internal network, as well as realizes dynamic equivalence of external network and online integration of external and internal networks. An implementation scheme of model integration taking into account external network equivalence is proposed in this paper.Based on the analysis of network model reconstructing,the key problem of model for interconnected power system is discussed in this paper. An implementation in Jiangxi provincial power system in central China is described to demonstrate the feasibility and applicability of the method proposed. A set of software based on the method has been developed and integrated into an online early warning and security countermeasure.At the same time,this model would be applied for new energy management system.
