Modeling method for heterogeneous dual-network coupling of power grid and communication network under the background of smart grid

Abstract

The invention provides a heterogeneous dual-network coupling modeling method of a power network and a communication network under the background of a smart grid, comprising the following steps: establishing a logic diagram model of a power network according to the characteristics of the power network; establishing a logic diagram model of a communication network according to the characteristics of the communication network; The heterogeneous dual-network coupling model is established on the basis of the logic diagram model and the communication network logic diagram model; the interaction between the power network logic diagram model, the communication network logic diagram model and the heterogeneous dual-network coupling model is realized in the time domain. According to the characteristics of the respective networks of the power network and the communication network, the present invention constructs a heterogeneous dual-network coupling model, which is mainly applied to the hybrid modeling and simulation of the power network and the communication network, and the simulation conclusions are used to evaluate the reliability of systems such as smart substations, micro-grids, and wide-area control and protection. sex and security etc.

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...

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 communication network (the The patent generally refers to power secondary equipment, communications, information systems, computer networks and other systems that are different from the physical network of the power grid) to provide information transmission, information collection and information processing, and the communication network will also have a potential impact on the power grid
