Abstract: This article presents a robust unified planning framework for a integrated energy system of electric heating gas (EHG-IES), which includes a hydrogen energy multi-scale regulation system (HEMRS). In addition to a multi-scale control system for hydrogen energy, the integrated energy system includes a power generation system comprising wind, solar, and micro gas turbines, as well as a thermal-electric storage system consisting of cogeneration units, batteries, and thermal storage tanks. To ensure the safe and stable operation of various equipment for production and daily life within the park, we propose a novel flexible and adjustable robust optimization (FARO) method to manage uncertainties arising from renewable energy fluctuations and electrical load demands. By linearizing complex nonlinear constraints, we formulated a FARO bi-level robust planning model characterized by mixed-integer linear features. This model was solved using a combined approach of stochastic bisection and the GUROBI commercial solver. Simulation results demonstrate the unique advantages of the EHG-IES with multi-scale hydrogen energy control in terms of economic costs and carbon reduction. The findings also validate the effectiveness of the FARO approach in addressing uncertainties from both supply and demand sides.
