Optimization operation strategy of cyber physical system of micro-energy grid based on Petri net

Micro-energy grid is a typical cyber physical system (CPS), which combines energy physical entity and cyber computing unit. Aiming at the coordination optimization problem of cyber physical system of micro-energy grid, an optimization operation method of micro-energy grid based on Petri net is proposed in this paper. Firstly, the cyber physical system architecture of micro-energy grid is given. Secondly, taking the minimum operation cost and maximum utilization of clean energy as the objective function, the optimal scheduling model of micro-energy grid was constructed. Then multi-agent system and Petri net theory are used to determine the operation optimization strategy of the whole system according to the power load. Finally, the validity and correctness of the proposed method are verified by an example simulation analysis, which is of great significance for improving energy utilization efficiency and economic benefit.
