The invention provides a distribution network information physical joint simulation platform and method. The platform comprises a digital test verification part and a dynamic model test verification part. The digital test verification part includes a distribution network dynamic model platform, a communication entity network and a master station physical device; the dynamic model test verificationpart includes RT-Lab, OPNET and a master station digital platform; the distribution network dynamic model platform and a distribution network digital platform form a power layer; the communication entity network and a communication digital platform form a communication layer; the master station physical device and the master station digital platform form a master station layer. The platform and the method can simulate dynamic interaction behavior of systems accurately and rapidly; digital simulation and dynamic model simulation are united and unified complement the advantages of each other; digital simulation is used for rapid modeling and parameter adjustment and the dynamic model simulation is used for simulating elements for which accurate digital modeling is impossible, and continuoussystem simulation and discrete event simulation are combined with a high-efficiency time synchronization method, so that the influence of a communication system in a distribution network on a power system in a CPS environment can be effectively verified.

Description

technical field [0001] The invention belongs to the field of distribution network simulation analysis, and in particular relates to a distribution network information-physics joint simulation platform. Background technique [0002] The modern distribution network contains a large number of physical networks, information equipment and computing units, and gradually develops into a large-scale cyber-physical system (CPS), and presents the coexistence of continuous systems and discrete systems, diversified operation modes, and network security. prominent problems. In order to solve these problems, it is necessary to increase a large number of communication facilities to realize the optimal control of distributed power generation and its coordinated control with the large power grid, and to achieve the intercommunication of primary equipment, control terminals and multi-level controllers. The above factors make the network topology of the distribution network more and more comp...
