Carbon Energy Flow Modeling and Optimization of Integrated Energy Systems Based on Petri Net

Integrated energy system is a system that realizes the cascading utilization and rational allocation of energy. However, it is difficult to observe its energy coupling characteristics during actual operation. Therefore, this paper combines the modeling principles of Petri net and proposes a carbon energy flow analysis model of integrated energy system based on Petri net. Then, based on the carbon energy flow model of the integrated energy system, an optimization model for the system was constructed, which considers the goals of energy conservation, carbon reduction, and economic efficiency fully. Meanwhile, dynamic carbon emission factors are incorporated into the carbon emission calculation, and an improved Particle Swarm Optimization (PSO) algorithm is used to solve the model, thereby obtaining the optimal output conditions for each device in the system. Finally, the effectiveness of the method is verified by comparing the simulation results of different optimization algorithms.
