Abstract:

In order to solve the problem of poor synchronization, discrete and continuous events coexist, a micro grid Petri monitoring model based on the structure of I type synchronous decomposition is proposed to improve the accuracy of the model construction of micro grid. Firstly, the research for Petri net system model of micro grid system was conducted, and the Petri network based main network model, micro source energy, storage system model, the standby power supply model and load model were built; Secondly, in order to improve the performance of Petri network model, the network structure decomposition method was used to construct Petri model based on the structure of I type synchronous decomposition, Petri complex control was multiple sets of simplified local subnet control problems; Finally, the effectiveness of the proposed model is verified based on micro grid Stateflow monitoring simulation system.

Key words: The structure of I type synchronous decomposition; micro grid, Petri net, sub network control, Stateflow simulation system
