Abstract: In this paper,a game theory-based optimal reconfiguration model for distribution network with hydrogen energy is proposed.The model integrates two sub-objectives,namely network security and load balancing,to conduct optimal reconstruction research on the distribution network system with hydrogen energy. Additionally,a modified particle swarm optimization（MPSO）method to solve the optimal reconfiguration model for distribution network system with hydrogen energy is introduced. To verify the effectiveness of the model and solution algorithm,as well as the impact of hydrogen energy units on the optimal reconfiguration results,the modified IEEE33 node system is simulated and analyzed. The simulation results demonstrate that the described gametheory-based optimal reconfiguration model and solution algorithm effectively achieve the optimal reconfiguration for distribution network system with hydrogen energy. Furthermore,the inclusion of hydrogen energy units,compared to units without hydrogen,significantly reduces the pressure of optimal reconfiguration on the distribution network system and improves the indices of network security and load balance.
