Optimal Configuration of Hydrogen Storage System and Hydrogen Supply Chain Equipment for Regional Integrated Energy System

Hydrogen can be produced from varieties of feedstock. Its ability to reduce the intermittency of renewable energy, along with its versatility in terms of producing or storing energy make it the perfect complement in a system in which renewable energies are the key players. Under the background of integrated energy system (IES), the hydrogen storage system and hydrogen supply chain equipment will be more widely used. This paper studies configuration of hydrogen storage system and hydrogen supply chain equipment in the regional integrated energy system, aiming at reducing wind curtailment and total cost. Firstly, a regional integrated energy system model with hydrogen storage system and hydrogen supply chain equipment is established. Then, aiming at economy, the optimal configuration model of hydrogen storage system and hydrogen supply chain equipment is established. Finally, the effectiveness of the model is verified by a practical example, and the MATLAB toolbox YALMIP with the CPLEX solver is used to conduct the IES configuration planning.
