Optimal Scheduling of Integrated Energy Network with Electricity-Hydrogen-Storage Considering Ladder Carbon Trading Mechanism

The integrated energy network (IEN) is one of the important forms of future energy system development. Low-carbon emission and economic operation are main aims for IEN. In order to improve consumption capacity of new energy sources, and improve its economy and environmental friendliness, this paper proposes an optimal scheduling method for electricity-hydrogen-storage integrated energy network (EHS-IEN) considering the carbon trading mechanism and dynamic weights and constructs a multi-objective optimal scheduling model to minimize operating costs and carbon emissions. The feasibility of the model is verified by the comparative analysis of the operating cost and environmental cost before and after the system optimization, and the influence of the carbon trading mechanism and different types of weights on the optimal scheduling of the EHS-IEN is analyzed. The simulation example analysis shows that the optimal dispatching model for EHS-IEN reduces carbon emissions and operation cost.
