Abstract

Green power trading has become a concerted global action to address climate change and promote green and low-carbon transformation, and its effect on carbon emission reduction in China's power sector is becoming increasingly pronounced. Exploring the development of China's green power trading market and assessing the impact of green power trading on the electricity market can promote the construction of a new type of power system and help realize the goals of reaching peak carbon emissions and carbon neutrality. The Beijing-Tianjin-Hebei region, one of the important economic hubs and urban agglomerations in China, fully launched green power trading in 2021. The study of green power participation in the electricity market in the Beijing-Tianjin-Hebei region can provide experience and policy references for the development of China's green power market. Therefore, this study analyzed the coupling mechanism between the green power trading market and the electricity market, proposed a non-cooperative game model considering the coupling between the two markets as well as a system dynamics model, and analyzed the impact of green power trading on the behavioral decisionmaking of market players and on the electricity market in the Beijing-Tianjin-Hebei region. The results showed that: 1 The proportion of green power generation affected the behavioral decisions of market players, and increasing the proportion of green power generation increased the profits of green power manufacturers and power grid enterprises and reduced the profits of thermal power plant operators and the cost of power purchases by electricity users. 2 Without considering the scenario of purchasing electricity from outside, feed-in tariffs for green and thermal power were on a downward and then upward trend; the green power installed capacity under construction and generation capacity were increasing, and the green power feed-in was estimated to account for about 63% of the total power in 2030; and the thermal power installed capacity under construction showed a rising, then falling, then rising trend. However, its rate of increase was smaller than that of green power. 3 Considering the scenario of purchasing electricity from outside, the green and thermal feed-in tariffs would decrease; thermal power generation would increase from January 2021 to April 2024, while thermal power generation would decrease from May 2024 to December 2030; green power generation would increase from January 2021 to April 2029 and decrease slightly from May 2029 to December 2030. The sensitivity analysis of purchased power revealed that increasing purchased power had a weakening inhibitory effect on thermal power in the region and promoted green power development. Based on the above conclusions, this study puts forward the following policy recommendations: accelerating the transformation of the power supply structure and promoting the changing roles of green power and thermal power in the power market; adjusting the pricing model of thermal power and promoting the multi-dimensionalization of electricity value; and encouraging inter-provincial and inter-regional green power trading to accelerate the construction of a unified national electricity market.

Abstract

As the most sensitive key area of the Earth system to global climate change, research on the key processes of the cryosphere has attracted much attention. Meanwhile, the inevitable trend in the multi-scale monitoring study of key processes of the Earth system is to move from digital surveying to intelligent surveying and mapping. This article summarizes the research status quo on the key processes of the Earth system in terms of intelligent observation and processing in five aspects:glacier melting and sea level rise, polar ice cap stability and subsurface structure, Arctic and Antarctic sea ice changes and extreme climates, permafrost degradation and geological disasters, and livable urban underground spaces under the Earth system. Furthermore, it provides the outlook of the development trend of the intelligent surveying and mapping of key areas and key processes of the Earth system, i.e., to improve the intelligent comprehensive monitoring network, to establish big data centers for key areas, and to build the intelligent model and prediction system of key processes.

Abstract

The 2030 Agenda for Sustainable Development, adopted by the United Nations in 2015, set 17 global Sustainable Development Goals (SDGs) with 169 targets. 232 indicators were proposed as the global framework for monitoring the progress made in achieving SDGs. SDG targets and their corresponding indicators interact with each other forming an indivisible system. This study examined the interlinkages between SDG targets in China and used 51 indicators and relevant time-series data mapping with 108 SDG targets to quantify the network of interlinkages between SDG targets. Using Social Network Analysis and Principal Component Analysis, we identified 17 strategic targets and 17 core indicators. The core indicators can explain more than 95% of the variance of 51 indicators. Using core indicators can reduce statistical burden while satisfying the needs for SDG monitoring. Based on the dashboard indicating the synergies and trade-offs between 17 strategic targets and other targets, this paper recommended that China should set 17 strategic targets as priority areas and optimise the use of limited financial resources by maximising the synergies and minimising the trade-offs.
