Configuration Optimization of Hydrogen-Based Multi-Microgrid Systems under Electricity Market Trading and Different Hydrogen Production Strategies

Hydrogen-based multi-microgrid systems (HBMMSs) are beneficial for energy saving and emission reductions. However, the optimal sizing of HBMMSs lacks a practical configuration optimization model reasonable solution method. To address these problems, we designed novel structure that combines conventional energy, renewable hydrogen subsystem. Then, established bi-level multi-objective capacity while considering electricity market trading different production strategies. The objective inner model, which is minimum annual operation cost, three objectives outer total cost (TAC); carbon (ACE); maximum self-sufficiency rate (SSR), researched simultaneously. solve above two-stage method, considers conflicts between objectivity weights, proposed. Finally, case study performed. results show when green strategies adopted, best scheme USD 404.987 million, 1.106 million tons, 0.486, respectively.
