“…A reasonable energy-abandonment rate is beneficial for reducing system consumption costs and improving system energy utilization efficiency. According to research calculations on the planned renewable energy installed capacity in 2025, the wind curtailment rate in the western region of China has decreased from 8.6% in 2020 to 7.8% in 2025 [25]. According to statistics from the National Energy Administration, the wind curtailment and light curtailment rates in the western region of China in 2022 were 6% and 2%, respectively.…”

“…When the primary aim is to achieve environmental sustainability, the objective function primarily takes into account the cost of carbon emissions. In the context of multi-objective optimization, it is common practice to integrate several individual objectives, including but not limited to maximizing economic gains, optimizing power quality, minimizing carbon emissions, and reducing output fluctuations [24][25][26][27][28]. The aforementioned scheduling models for pumped storage stations in the context of combined power generation system from diverse energy sources represent optimal solutions.…”

With large-scale grid-connected renewable energy, new power systems require more flexible and reliable energy storage power sources. Pumped storage stations play an important role in peak shaving, valley filling, and promoting renewable energy consumption. This paper presents the reasonable energy-abandonment operation of a combined power generation system (CPGS), in which a pumped storage station is the core control power, with an ultra-high proportion of renewable energy. Firstly, based on the seasonal characteristics of wind, solar, and load demand, typical days are selected through improved clustering analysis algorithms. Then, a daily optimal scheduling model for combined power generation systems (CPGS) is developed with the goals of economy, low-carbon, and stable operation. Finally, the correlation between the energy-abandonment rate and pumped storage station peak shaving and system optimization operation indicators is obtained by a reasonable energy-abandonment calculation method considering source-grid-load coordination. Taking the operation data of an energy base in the western region of China as an example, when the penetration rate of renewable energy is 60–70% in the future, the operating cost on the power side is greatly affected by the construction of the source side. When the system operates at a planned reasonable energy-abandonment rate of 2%, electricity regulation, load tracking, and daily operating costs all show better performance.

“…Additionally, this study proposes a unique multi-subject joint operation mode for the Re-gas circulation box, which enables "benefit sharing and risk sharing" throughout the entire supply chain of express boxes. The circular express box solution suggested in this study aims to contribute to environmental protection and conservation, promote the clean, low-carbon, green, and sustainable development of the express delivery industry, and aid the country in achieving carbon neutrality as soon as possible [3] . become a pressing issue that the government is closely monitoring and urgently needs to address.…”

In recent years, with the vigorous development of e-commerce, China's express delivery industry has experienced a peak of development. However, the production of express garbage during this process has led to serious environmental pollution problems. The relevant national policies have also set higher requirements for the reduction, standardization, and recycling of express boxes. Therefore, it is urgent to reduce the size of the express box. It has been observed that many express delivery companies have joined the "green revolution" of promoting express delivery boxes. However, due to factors such as cost and safety, the utilization rate of circular express delivery boxes has not improved. Based on the current situation analysis, this study will address the existing problems and challenges of the current circulating box in practical applications. It will consider designing a green, shared, and circulating express box that can be implemented with existing technology. Therefore, this study is based on RFID technology to conduct innovative research and development, design a circular shared express box named Re-gas, and establish a closed-loop system for the supply chain of express boxes. This will promote the green and efficient transformation of the express industry. However, because the designed and manufactured express box samples have not been tested, and due to limitations imposed by application scenarios, cost control, and industry barriers, the project may have some defects and challenges.
