Abstract
In this paper, a novel methodological framework for energy hub (EH) planning, considering the correlation between renewable energy source (RES) and demand response (DR) uncertainties, is proposed. Unlike other existing works, our study explicitly considers the potential correlation between the uncertainty of integrated energy system operations (i.e., wind speed, light intensity, and demand response). Firstly, an EH single-objective interval optimization model is established, which aims at minimizing investment and operation costs. The model fully considers the correlation between various uncertain parameters. Secondly, the correlation between uncertainties is dealt with by the interval models of multidimensional parallelism and affine coordinate transformation, which are transformed into a deterministic optimization problem by the interval order relationship and probability algorithm, and then solved by a genetic algorithm. Finally, an experimental case is analyzed, and the results show that the research method in this paper has good engineering practicability. At the same time, different correlations among uncertainties have different influences on integrated energy system planning. Correlation and influence are positively correlated.

According to the energy hub (EH) load level on the user side, and combined with the simulation results obtained by adjusting the upper limit value of the equipment in the early stage, the maximum configurable capacity of CHP, renewable distributed power supply and electric–thermal boiler were set as 2000 kW, 1000 kW and 1000 kW, respectively
The is because reasonable pricing of environmental costs can help stimulate enthusiasm energy systems is proposed, which considers the correlation between market uncertainties
Summary
Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. With increasingly prominent environmental problems and the gradual depletion of energy, it has become an irresistible trend to make full use of RES to generate electricity. Fossil energy was the main source of electricity generation. Compared with the traditional electric energy utilization mode, the integrated energy system realizes flexible conversion and unified management of different energy sources, with the help of advanced conversion and storage equipment. It provides a new solution for carbon emission control and economic construction [1]
