Hierarchical distributed hybrid computing architecture system and method for electric power cyber-physical system

Abstract

The invention discloses a layered distributed hybrid computing architecture system of an electric power cyber-physical system. The hybrid computing architecture system of the electric power cyber-physical system includes three independent subsystems, and the subsystems are a communication layer hybrid computing system and a secondary equipment layer. Hybrid computing system and cyber-physical system hybrid computing system, each subsystem supports the analysis and processing of different characteristics of the model at this layer; the subsystems communicate with each other through the data interaction interface; multi-time scale and multi-management for power cyber-physical systems In order to solve the problems of subject, data interaction security and model complexity, a layered and distributed computing algorithm system and model simplification method were proposed, and a mechanism for models and algorithms to respond on demand was established, which realized the rationalization of complex power cyber-physical system models. Simplified, fast calculation and precise analysis, and has good data security and scalability.

Description

technical field [0001] The invention belongs to the field of electric power information physical coupling system, and specifically relates to a layered distributed hybrid computing architecture system and method of electric power information physical system. Background technique [0002] With the rapid development of computing technology, communication technology and intelligent control technology, once proposed, Cyber-Physical Coupling System (CPS) has attracted extensive attention from academia and industry and has maintained rapid development. With the continuous development of smart grid construction, the number of grid sensors, the scale of information network and the number of decision-making units have all increased rapidly, and the degree of automation of the power system has been greatly improved. In addition, the promotion of the Energy Internet has made more and more external information directly or indirectly affect the power system control decision-making throug...

AI Technical Summary

Problems solved by technology

In addition, the promotion of the Energy Internet has made more and more external information directly or indirectly affect the power system control decision-making through various business channels, and the interaction mechanism between the power network and the information network is becoming increasingly complex.

The modern power system has developed into a power cyber-physical system (power CPS) with various typical characteristics of CPS. However, in the prior art, there is a lack of a hierarchical distributed hybrid computing system of the power cyber-physical system, and it is impossible to use CPS technical means to analyze power CPS for modeling and hybrid calculations

The existing research on modeling and hybrid computing for power CPS has just started, and most of them are modeling and computing for specific power business, without forming a specific theory and method system, which has great limitations
