With the release and gradual implementation of the “carbon peaking and carbon neutrality” policy, renewable energy is integrated into power grids on a large scale, and its uncertain and intermittent supply challenges the stability of the power system. The new power system integrated with renewable energy is faced with a new challenge in terms of frequency security, while the extreme climate in recent years has made it more difficult to achieve power balance in the power system. As an integral part of the load side, the flexible power regulation of industrial enterprises is now attracting attention. With focus on the exploitation of flexible power regulation resources under industrial load, this paper builds various industrial load models for industrial enterprises, promotes the deep integration of Industrial Internet and Energy Internet, conducts research on the exploitation of flexible resources and power grid regulation technologies driven by Industrial Internet under industrial load, and analyzes the direct and indirect benefits of the research. The research results are of great significance to the safe and stable operation of the power system, the consumption of new energy, and the green and low-carbon transformation of the industry.

In this study, a kind of ZnO/NiO/CeO2 nanocomposite constructed by solution method was adopted to remove malachite green (MG) dye from water. The nanocomposite was characterized by Zeta potential, SEM, TEM, FTIR, XRD, XPS and BET analysis. The results indicate that ZnO/NiO/CeO2 has hierarchical porous structure containing micropores, mesopores and macropores. Through the study of the adsorption process, the adsorption performance of ZnO/NiO/CeO2 was evaluated systematically. The adsorption conditions such as initial concentration of dye, pH value and adsorption time were considered, and the equilibrium adsorption and kinetic were described by different isotherm and kinetics models. We demonstrate that ZnO/NiO/CeO2 composite displays preferential adsorption performance to cationic dye MG with great adsorption capacity of 7600 mg g−1. The ZnO/NiO/CeO2 nanocomposite displays highest removal rate when pH is 7, with adsorption time of 60 min at room temperature. The pseudo-second-order kinetic and Langmuir isothermal models are well applied to the adsorption process of MG on ZnO/NiO/CeO2. The adsorbent can be recycled for four times and maintain good adsorption performance all the time. [ABSTRACT FROM AUTHOR]
