In response to the country's "carbon neutrality, peak carbon dioxide emissions" task, this paper constructs an integrated energy system based on clean energy. The system consists of three subsystems: concentrating solar power (CSP), compressed air energy storage (CAES), and absorption refrigeration (AR). Among them, thermal energy storage equipment in the photothermal power generation system can alleviate the fluctuation of solar energy and provide a stable power supply for the system. The compression heat generated during the compression process of the CAES system can be recovered through heat transfer oil to provide a heat load. The compressed air in the air accumulator (ACC) expands in the air turbine to provide an electric load. The low-temperature exhaust gas discharged from the turbine can provide cool load. First, a multienergy system that includes CSP, CAES, and AR is built. Then, the system takes the lowest economic cost as the objective function and constructs the system day-ahead scheduling model. Finally, for data obtained from scene reduction, the commercial optimization software Gurobi is invoked through YALMIP to solve the model. The results show that the three subsystems achieve multienergy complementarity; system operating costs are reduced by 59.94% and fully absorb wind and solar energies by the system.

“…The main goal in energy system integration is to take advantage of the synergies and complementary strengths offered by various forms of energy carriers (Wu et al, 2016) (energy carriers that are also referred to as energy vectors). Research in this area covers a broad range of concepts and topics, including multi-vector energy systems (Hosseini et al, 2020), multi-carrier energy systems (Alabi et al, 2023;Zhang et al, 2023), integrated energy systems, and energy systems integration (Wu et al, 2022).…”

As the global community faces unprecedented climate change challenges, the transition towards a sustainable society has become an urgent priority. The complexity of this transition is characterised by the interplay of developing and implementing green manufacturing processes, integrated energy systems, and circular resource flows, and the inherent dynamics associated with geopolitical uncertainties, energy price fluctuations, and global instability. Although new technological advancements and more sustainable models are on the rise, a significant knowledge gap remains in comprehending the intricate dependencies and impacts of various uncertainties on complex industrial and energy systems. Dependency means that one component, subsystem, or variable relies on another for its operation or effectiveness. A change in one element will directly affect the other, causing changes in its status or actions. Because the components are interconnected in this way, they are not independent of each other. This knowledge gap is particularly noticeable in the lack of a comprehensive understanding of the interactions between the energy system and uncertainties. This became significantly more apparent during events such as the COVID-19 pandemic and the subsequent Russian invasion of Ukraine. IntroductionAbundant, clean, and affordable energy is crucial for realising the vision of a modern, industrialised, and sustainable society (Tainter, 1988). Hence, a systemic shift towards a renewable and electrified energy system on a massive scale is necessary to achieve rapid emissions reductions (IPCC, 2023). If new energy demand and electric power capacity were instead built on fossil fuels rather than renewable sources, the consequences could be severe. This would worsen climate change, as electricity generation based on fossil fuels leads to ongoing emission of carbon dioxide and other greenhouse gases. It could also entrench unsustainable infrastructure for an extended period, thereby prolonging the unsustainable reliance on limited fossil resources (IPCC, 2023). Furthermore, persisting reliance on fossil fuels could compromise energy security (Correlje & Van der Linde, 2006;Yergin, 2006).Transitioning to renewable energy sources can avert these risks, promoting a more self-reliant, sustainable, and secure energy future (IEA, 2022b). This involves adopting low-or zero-emission technologies and biogenic energy sources (Demirbas, 2009), curbing energy and material demand, modifying behavioural patterns, and enhancing efficiency. The diminishing carbon budget means that energy systems must quickly transition towards net-zero CO2 emissions by decreasing fossil fuel dependence, applying carbon capture, widespread electrification, utilising and improving energy conservation, efficiency, and energy system integration (IEA, 2022b(IEA, , 2023bIPCC, 2023).The growth of renewable energy is not just about increasing renewable electric power capacity and biogenic energy sources; rather, it is more about incorporating and coordinating multiple technol...

The interactive demand of electrical power between integrated energy microgrid (IEMG) and smart distribution network (SDN) is growing rapidly with the increase of distributed generation (DG) installed capacity. When SDN and IEMG are connected through a single gird‐connected point, the renewable power consumption may be limited by tie‐line capacity. A distributed optimal dispatching method of the SDN considering the IEMG with multiple gird‐connected points is proposed. The impact of various flexible resources is also considered. Firstly, a IEMG connection mode, in which each IEMG can be connected to multiple nodes of the SDN, is designed. A distributed optimal dispatching method is proposed, by which the IEMG operation privacy and the SDN responsibility to consume renewable power can be considered. Then, the electric power on tie‐lines is taken as the coupling variable to establish the IEMG and SDN coordinated dispatching model. The model can be solved by adjusting the power upper limits of tie‐lines circularly. Finally, the improved IEEE 33‐bus system is analysed based on the proposed method. It is found that when the IEMG is with large DG installed capacity, multiple gird‐connected points can improve the SDN operation flexibility and increase the operation benefits of all entities.
