Research on the Key Issues of Constructing Southern Regional Power Market in China

To reach the “30·60” decarbonization target (where carbon emissions start declining in 2030 and reach net zero in 2060), China is restructuring its power system to a new energy-based one. Given this new situation, this paper reviews previous studies on the power market and highlights key issues for future research as we seek to adapt to the new power system (NPS). Based on a systematic literature review, papers on the operational efficiency of the power market, participants’ bidding strategies and market supervision were identified. In a further step, papers with high relevance were analyzed in more detail. Then, key studies that focused on market trading under China’s new power system were picked out for further discussion. New studies were searched for that pertained to new energy mechanisms and bidding, the transition from coal-fired power, flexible resources and the technical applications of simulations. The quantitative analysis supports the construction of a basic paradigm for the study of power markets that is suitable for the new power system. Finally, the theoretical basis and application suggestions for power market simulations are introduced. This study summarized the existing research on the power market and further explored the key issues relating to the power market as it adapts to the NPS, hoping to inspire better research into China’s power sector, and promote safe, low-carbon, and sustainable development in China’s power industry.

Power Trade

South Asia is the fastest growing region in the world and is experiencing increasing demand for energy. As a result, countries are witnessing an excessive reliance on fuel imports, making themselves vulnerable to external price volatility and compromising on energy security. Power trade in South Asia can meet the challenge of increasing energy demand owing to complementarities in resource endowments and peak demand. Power trade in South Asia has increased over the years but is below potential. However, there are various challenges due to lack of institutional structures and frameworks for developing regional power trade models. The examples of power integration models in Europe, that is, the Nordic power market, and in Southeast Asia, that is, power trade in the Greater Mekong Subregion (GMS), can provide useful lessons and international best practices for regional power trade to be replicated in the South Asian context. Based on this, the objective of this article is to evaluate the existing power trading mechanisms in South Asia, highlight the challenges to regional energy cooperation, outline the necessary instruments and catalysts to promote regional power trade in South Asia based on the case study of successful power trading arrangements, including the Nordic power market in Europe and the Greater Mekong Subregion (GMS) in Southeast Asia, draw on their experiences to identify key mechanisms and develop a template for greater regional cooperation in electricity in South Asia.

Key Issues

In electron energy loss spectroscopy (EELS), the near-edge region of a core-loss edge contains information on high-order atomic correlations. These correlations give details of the 3-D atomic structure which can be elucidated using multiple-scattering (MS) theory. MS calculations use real space clusters making them ideal for use in low-symmetry systems such as defects and interfaces. When coupled with the atomic spatial resolution capabilities of the scanning transmission electron microscope (STEM), there therefore exists the ability to obtain 3-D structural information from individual atomic scale structures. For ceramic materials where the structure-property relationships are dominated by defects and interfaces, this methodology can provide unique information on key issues such as like-ion repulsion and the presence of vacancies, impurities and structural distortion.An example of the use of MS-theory is shown in fig 1, where an experimental oxygen K-edge from SrTiO3 is compared to full MS-calculations for successive shells (a shell consists of neighboring atoms, so that 1 shell includes only nearest neighbors, 2 shells includes first and second-nearest neighbors, and so on).
