Energy management optimization of integrated energy system with electric hydrogen hybrid energy storage

Abstract

Integrated energy system (IES) has attracted wide attention as an efficient solution to a comprehensive utilization of hybrid energy system including electricity, heat, and hydrogen in recent years. This paper investigates the stochastic optimal operation for the micro integrated electric power, heat, and hydrogen delivery system. Firstly, the mathematical model of the micro integrated energy system for residential communities and other similar scenarios is discussed, including the energy interface, power microgrid, micro-heat system and micro-hydrogen system with considerations of distributed energy supply, energy storage, load, upstream energy network interface and their mathematical models. Secondly, the correlated uncertainty, such as wind power, solar power, and loads, are considered and handled in micro integrated energy system. Finally, a scenario-based approach is proposed for the stochastic operation of micro integrated energy system. The objective function is formulated to minimize the expected total operation and environmental costs, the hourly schedule of controllable components in micro integrated energy system. Numerical results demonstrated that the effectiveness of the proposed method. The correlated uncertainty and the corresponding impacts are accurately presented in the optimization model.

“…A few technologies that can be installed at home to make a change include small solar and wind electric systems and microhydrogen power systems. 38 The Indian Government for example has released new incentives to promote clean energy. A program, Facility for Low Carbon Technology Deployment (FLCTD), implemented by the Bureau of Energy Efficiency (BEE) and the United Nations Industry Development Organization (UNIDO) was proposed which aimed for the identification of innovative low carbon technologies and to support up to $50,000 for validation and commercialization in the industrial sectors of the Indian economy.…”

Capacity Optimization Configuration for a Park-Level Hybrid Energy Storage System Based on an Improved Cuckoo Algorithm

“…After comparing multiple scenarios, it was found that incorporating power interaction constraints in the capacity optimization model helps to reduce the cost of microgrids and improve stability. An electric and hydrogen energy storage system is proposed by Huang et al [9], which is used to regulate the fluctuation of photovoltaic systems and to fulfill the demand for electric and hydrogen loads on the user side. Du et al [10] developed a two-tier optimization model.…”
