Abstract
This paper firstly proposes a hydrogen energy hub to satisfy the diverse hydrogen demands of industrial users consuming renewable energy for low-carbon emissions. In the hydrogen energy hub, two techniques, i.e., water electrolysis and biomass gasification, are coupled through complementary oxygen utilization. Then, an industrial integrated energy distribution system is formally constructed by incorporating multiple hydrogen energy hubs, battery energy storage, renewable energy sources, and a gas generator to coordinate local renewable resources. Accordingly, a real-time energy management system for a hydrogen energy hub-based industrial integrated energy distribution system is further proposed to efficiently coordinate multiple resources in the distribution network. To minimize the real-time operational cost of an industrial integrated energy distribution system under stochastic environments of time-variant renewable generation, biomass moisture content, electricity prices, and electrical loads, multidimensional piecewise linear function-based approximate dynamic programming is adapted. Finally, case studies validate the techno-economic benefits of the proposed system and the advantages of the proposed algorithm.
