Special Issue Information

Dear Colleagues,

The global consumption of fossil fuels continues to increase, resulting in the depletion of the ozone, climate changes, environmental issues, and increased health risks. It is, therefore, urgent to develop future energy systems based on sustainable and low-carbon technologies. With increasing promotion of carbon neutrality and sustainability across the globe, numerous studies have been conducted to exploit sustainable and low-carbon technologies to optimize the the structure of energy systems. In the past decades, renewable energy systems, such as solar, wind, and hydro power, have been developing rapidly and fundamentally changed the global energy market. In addition, some emerging technologies with promising potentials are under development, including cellulosic ethanol, hot dry rock geothermal power, and marine energy.

This Special Issue will collect original research and review articles on recent findings in the areas of sustainable and low-carbon technologies that play a crucial role in future energy systems. Studies can be conducted at the level of a particular technology or component of the energy system through numerical simulation, experimental measurements, and energy systems analysis. Authors are asked to declare the research objectives, state all the assumptions used to derive new models, and clearly define research hypothesis.

With the increasingly prominent environmental problems in the world today, the development of an integrated energy system and the introduction of a carbon-trading mechanism have become important means to realize the low carbonization of the energy industry. Based on this, this paper introduces the carbon-trading mechanism into the research on the optimal dispatch of an integrated energy system. The mechanism of integrated energy demand response participating in low-carbon economic dispatch is analyzed. The relationship between carbon emissions and carbon-trading price in carbon-trading mechanism is described. On the basis of considering the commodity attributes of the electricity and gas load and the flexible supply characteristics of the thermal load, an incentive-type comprehensive energy demand response model is established. Finally, aiming at the lowest comprehensive operating cost, a comprehensive energy system model considering the power balance and equipment constraints of the electric–gas–heat system is established, using an improved particle swarm algorithm to solve it. Simulations verify the effectiveness of the proposed method in reducing the carbon emissions and operating costs of integrated energy systems. Full article

Increasing extreme rainfall events caused by global climate change have had a significant impact on urban drainage systems. As a critical component of a pumping station, a large-scale slanted axial-flow pump (SAFP) featuring high specific speed plays a critical role in mitigating urban flooding and waterlogging. In this study, to reveal the transient characteristics of a SAFP at shut-off conditions, a computational fluid dynamics (CFD) based approach with dynamic mesh was proposed. Multiple shut-off conditions with various shut-down speeds of the sluice gate (SG) were modeled. Our analysis demonstrated that both the shut-off conditions and the slanted structure have conspicuous impacts on the hydrodynamic performance of a SAFP. Reducing the shut-down speed leads to a greater reverse flow rate and higher runner speed. The water hammer effect was simulated with different shut-down speeds, increasing the water head by 5.07–10.42 m, the axial force by 163.46–297.06 kN∙m, and the axial moment by 116.05–224.01 kN∙m. Compared with the axial direction, moments in the radial directions were found with more obvious oscillation as a result of stronger rotor–stator interaction. Due to the gravitational effect of the slanted structure, the fluctuation of the runner in vertical direction presented an off-axis characteristic compared with the horizontal one. As the SG speed increased, pressure fluctuations gradually decreased at various locations across the SAFP. Full article
