Embodiment 2

[0052] Before the co-simulation is started, in the co-simulation scenario configuration link, both simulators can know the data requirements of the information communication simulator to the power system simulator, that is, the data type and the update cycle of the data. According to this demand information, the power system simulator can determine its own step time length (StepTime), so that it can provide simulation data that meets the time interval requirements; and the "data receiving agent" can initialize the corresponding time interval in the event queue of the information communication simulator. Time interval for "data sampling events". Similarly, both simulators can know the type of data (such as control instructions) transmitted from the information communication simulator to the power system simulator, but the transmission time is random.

[0053] The present invention relates to a method for time synchronization and data exchange of co-simulation of electric power ...

Abstract

The invention discloses a time synchronization and data exchange apparatus and method used for combined simulation of a power system and an information communication system. The time synchronization and data exchange apparatus comprises an information communication system simulation synchronization apparatus and a power system simulation synchronization apparatus. A "peer-to-peer" synchronous system framework is adopted, so that both an information communication simulator and a power system simulator can flexibly and actively send data. An event queue is arranged on each of two sides and used for forwarding data with a time stamp and event starting time, and also serves as a "synchronous time axis", so that two simulation platforms are enabled to keep time synchronous while the data is transmitted. In a simulation process, the two simulators concurrently execute respective simulation tasks by reference to the "synchronous time axes" on the own sides, and when the speeds of the two simulators are not matched, the two simulators are suspended for waiting for each other.

Description

technical field [0001] The invention relates to power system simulation, in particular to a device and method for time synchronization and data exchange used for joint simulation of power system and information communication system. Background technique [0002] With the rapid development of smart grids, advanced information and communication technologies have been widely used in power systems. The information communication system and the physical power system are coupled with each other to form an information power coupling network system. The information power coupling network is a hybrid system of continuous dynamic and discrete time coupling. Among them, the power system is a continuous system, and the information and communication system is a discrete event system. At present, when simulating the information-power coupling network, the dynamic simulation of the power continuous system and the information discrete event system is usually combined, that is, the power sy...
