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

Abstract

The invention discloses a hierarchical distribution type hybrid calculation architecture system of an electric power information physical system. The hybrid calculation architecture system of the electric power information physical system comprises three independent sub-systems. The three sub-systems are composed of a communication layer hybrid calculation system, a secondary equipment layer hybrid calculation system and an information physical system hybrid calculation system. Each sub-system enables the analysis and the treatment on different characteristics of a current layer model. All sub-systems are in mutual communication with one another through data interaction interfaces. According to the invention, a hierarchical distribution type calculation algorithm system and a model simplification method are provided for solving problems in the prior art, including the multi-time scale, the multi-management main body, the data interaction safety and the model complexity of the electricpower information physical system. A model and algorithm on-demand response mechanism is established. The reasonable simplification, the rapid calculation and the accurate analysis of a complex electric power information physical system model are achieved. Meanwhile, the advantages of good data safety and expandability are achieved.
