“…The phenomenon that results in the loss of electrical energy during transmission. Line loss is an important index to measure the running quality of power system [18][19]. The corresponding amount of carbon dioxide in this part of the network loss is defined as the carbon dioxide emissions in the power transmission stage, which can be calculated by the following formula:…”

As an important transmission corridor of "West-east power transmission" and the central hub of the power grid in northwest China and has obvious resource advantages in the power and location of the country. And it will accelerate the construction of a new power system to adapt to the gradual increase in the proportion of new energy, from the traditional energy consumption structure dominated by coal power to the new energy consumption structure, new energy will enter the stage of high-quality leapfrog development, in order to achieve the "double carbon" goal as soon as possible. Based on the analysis of carbon emissions in Gansu province, especially in the power industry, this paper demonstrates the overall situation of carbon emissions in Gansu province, and points out the status of new energy in Gansu province combined with the latest energy resources and the existing regional development situation, and puts forward relevant suggestions to adapt to the development of new energy in Gansu province under the "dual carbon" goal.

“…To achieve the goal of carbon neutrality, many countries propose to vigorously develop renewable energy sources represented by solar energy, wind energy, and so on (Li et al, 2021). This move can effectively improve the current situation of relying on fossil energy for energy supply and mitigate environmental problems taken from the energy supply processes (Wang S. et al, 2023;Lin and Zhang, 2023). According to a survey by the International Energy Agency, the scale of renewable energy will expand rapidly over the next few years, and be the largest source of electricity supply by early 2025 (Agency and International Energy, 2022).…”

Thermal integrated pumped thermal energy storage (TIPTES) systems with the features of high efficiency, flexibility, and reliability, have attracted increasing attention since they can integrate low-grade heat sources to further improve the utilization and economic viability of renewable energy. In this study, a typical TIPTES system driven by waste flue gas is established, and the heat pump and organic Rankine cycle (ORC) are chosen as the charging and discharging cycle, respectively. Four organic fluids, including R600, R245fa, R601a, and R1336mzz(Z), are selected to compose sixteen different working fluid pairs for thermodynamic analysis. The effects of key parameters, like heat pump system evaporation temperature and hot storage tank temperature, on system performance were analyzed, and the single-objective optimization was conducted. A comparative study was carried out to identify the best working fluid pair according to the optimization results. Results show that the system’s power-to-power efficiency goes up as the evaporation temperature increases while an increase in the heat storage temperature decreases the exergy efficiency of the TIPTES system. Optimization results show that the R245fa + R245fa is the best working fluid pair, and in this system, the ORC evaporator has the largest exergy destruction at about 260.84 kW, which is 20.2% of the total. On the other hand, the ORC pump has the smallest exergy destruction only about 0.5%. This study also finds that the system’s power-to-power efficiency of using different working fluids in either heat pump cycles or ORC cycles is lower than that of using the same working fluid throughout the entire system.
