Analysis of New Energy Consumption and Carbon Emission Reduction in an Electric-Hydrogen Integrated Energy System

The continuous increase in the installed capacity of new energy in the power system highlights the critical importance of effectively enhancing the integration of these energy sources. This paper achieves the mutual conversion of electrical energy and hydrogen energy by introducing hydrogen storage devices into the power system. Building upon this, optimization objective function is established, specifically minimizing the sum of system generation cost and carbon emission cost. Two different dispatching modes are designed accordingly. A case study is conducted to compare the effects of these two dispatching modes. Simulation results demonstrate that the integrated electricity-hydrogen energy system can effectively promote the integration of new energy and reduce carbon emissions. In conclusion, the paper provides a comprehensive summary of its findings.
