Scheduling Optimization of Integrated Electricity and Green Hydrogen Storage System for Power Transmission-Distribution Coordination

This paper presents a new economic-oriented optimization for the coordinated scheduling of power transmission and distribution systems, with a particular focus on integrating green hydrogen storage with offshore wind energy. The designed objective is to maximize annual revenue by considering both electricity and hydrogen revenues while reducing electricity purchase costs. With a case study, the optimal results of the coordinated system are obtained and analyzed. This is compared with results for a system that employs a single storage system located only at the production side. This comparison highlights the economic advantages of situating electrolyzers and hydrogen storage systems at both the production and consumption ends, and improved coordination between the transmission and distribution of electricity.
