Electric network and communication network heterogeneous dual-network coupling modeling method under background of intelligent power grid

Abstract

The invention provides an electric network and communication network heterogeneous dual-network coupling modeling method under background of an intelligent power grid. The electric network and communication network heterogeneous dual-network coupling modeling method under background of the intelligent power grid comprises the following steps: building an electric network logic diagram model according to the network characteristic of the electric network; building a communication network logic diagram model according to the network characteristic of the communication network; building a heterogeneous dual-network coupling model based on the electric network logic diagram model and the communication network logic diagram model; realizing interaction among the electric network logic diagram model, the communication network logic diagram model and the heterogeneous dual-network coupling model in time domain. The heterogeneous dual-network coupling model is built aiming at the network characteristic of the electric network and the communication network, the modeling method is mainly applied to the hybrid modeling simulation for the electric network and the communication network, the simulation result is used for estimating the reliability and safety of the intelligent substation, micro-grid and wide-area control protection system.

Description

technical field [0001] The invention relates to a modeling method, in particular to a modeling method for heterogeneous dual-network coupling modeling of a power network and a communication network under the background of a smart grid. Background technique [0002] The power grid is an important platform for energy allocation and transmission, and the communication network is a guarantee for social informatization and intelligence. Two networks are important infrastructure in modern society. At present, the power industry and the communication industry adopt different methods to model the power grid and communication network. In fact, the correlation between these two systems is getting bigger and bigger. A power failure may cause the communication network to be paralyzed, and the power grid will cause electromagnetic interference to the communication network. On the contrary, the smart grid emphasizes that the operation control of the modern power grid requires the communi...
