Energy Price-Driven Integrated Demand Response for Optimal Operation of Multi-Carrier Energy Systems with Hydrogen Facility

With the continuous advancement of the Chinese national “dual carbon” strategic goal, the green and low-carbon transformation of the multi-carrier energy system (MES) is an important path to achieve this goal. In order to fully explore the integrated demand response (IDR) ability of the MES and the influence of hydrogen utilization on the system optimal scheduling, this paper proposes an economically low-carbon cooperative optimization operation strategy for hydrogen-containing electric-thermal MES driven by energy price. Firstly, a hydrogen facility composed of electrolyzer (EL), fuel cell (FC) and hydrogen storage tank (HST) is constructed. Secondly, a MES model based on price elasticity matrix is established. Finally, with the objective of minimizing the operation costs, the effectiveness of the proposed strategy is verified by different scenarios' simulation using MATLAB and Gurobi optimization solver. Through the analysis of the system operating status under different scenarios, it is found that IDR can achieve economically, low-carbon, and efficient operation of MES. The introduction of a hydrogen utilization system can improve energy utilization efficiency and enhance the system's operational flexibility.
