Application and research of global grid database design based on geographic information

global energy interconnection 2018年第1期1卷 87-95页

作者： Xuming Liang global energy interconnection development and cooperation organization

energy crisis and climate change have become two seriously concerned issues universally. As a feasible solution, global energy interconnection(GEI) has been highly praised and positively responded by the international community once proposed by China. From strategic conception to implementation, GEI development has entered a new phase of joint action now. Gathering and building a global grid database is a prerequisite for conducting research on GEI. Based on the requirement of global grid data management and application, combining with big data and geographic information technology, this paper studies the global grid data acquisition and analysis process, sorts out and designs the global grid database structure supporting GEI research, and builds a global grid database system.

The Impacts and Adaptation of Climate Extremes on the Power System:Insights from the Texas Power Outage Caused by Extreme Cold Wave

引用

Chinese Journal of Urban and Environmental Studies 2022年第1期10卷 61-76页

作者： MA Zhiyuan ZHAO Zijian LIU Changyi YANG Fang WANG Mou global energy interconnection development and cooperation organization (GEIDCO) Research Centre for Sustainable development Chinese Academy of Social Sciences University of Chinese Academy of Social Sciences Research Institute for Eco-civilization Chinese Academy of Social Sciences

Along with the aggravation of climate change, various weather and climate extreme events(abbreviated as climate extremes) are becoming more frequent. During the transition to the use of clean energy, the power system will show increasingly prominent features such as high ratio of clean energy, high ratio of electrification, and a high proportion of electric and electronic equipment, coupled with summer and winter load peaks. Against this backdrop, this paper studies the impacts of climate extremes on the power system using the Texas power outage as an example,and proposes general adaptation measures to cope with climate extremes. For a start, this paper reviews the power outage in Texas caused by an extreme cold wave across the North America in 2021, and conducts an in-depth analysis of its causes. Then, based on the theoretical framework of disaster risk management, this paper analyzes the weather and climate disaster risks, extreme events, exposure, and vulnerability faced by the power system in the context of climate change and extreme events. Finally, in order to build a new power system, this paper establishes an overall framework for the power system to mitigate and adapt to climate change, and summarizes the key techniques involved in power generation, transmission, distribution, and consumption, as well as key technologies in the fields of power supply, power grid, power load, and energy storage, and the strategies and measures for addressing climate change.

Recent developments in HVDC transmission systems to support renewable energy integration

引用

global energy interconnection 2018年第5期1卷 595-607页

作者： Zhou Li Ruopei Zhan Yazhou Li Yan He Jinming Hou Xiaoling Zhao Xiao-Ping Zhang Southeast University global energy interconnection development and cooperation organization University of Birmingham

The demands for massive renewable energy integration, passive network power supply, and global energy interconnection have all gradually increased, posing new challenges for high voltage direct current(HVDC) power transmission systems, including more complex topology and increased diversity of bipolar HVDC transmission. This study proposes that these two factors have led to new requirements for HVDC control strategies. Moreover, due to the diverse applications of HVDC transmission technology, each station in the system has different requirements. Furthermore, the topology of the AC-DC converter is being continuously developed, revealing a trend towards hybrid converter stations.

Full electromagnetic transient simulation for large power systems

引用

global energy interconnection 2019年第1期2卷 29-36页

作者： Yong Tang Lei Wan Junxian Hou China Electric Power Research Institute global energy interconnection development and cooperation organization

For building global energy interconnection(GEI), it is necessary to implement new breakthroughs on largepower system simulation. Key routes for implementing full electromagnetic transient simulation of large-power systems are described in this paper, and a top framework is designed. A combination of the new large time step algorithm and the traditional small-time step algorithm is proposed where both parts A and B are calculated independently. The method for integrating the Norton equivalence of the power electronic system to the entire power grid is proposed. A two-level gird division structure is proposed, which executes a multi-rate parallel calculation among subsystems and element parallel calculation in each subsystem. The initialization method of combining load flow derivation and automatic trial-and-error launching is introduced. The feasibility of the method is demonstrated through a practical power grid example, which lays a foundation for further research.

Poverty Reduction Effect of Adaptation to Climate Change: Empirical Evidence from China's Loess Plateau and Qinba Mountains

引用

Chinese Journal of Urban and Environmental Studies 2020年第3期8卷 102-115页

作者： LIU Jie LIU Changyi International Business School Shaanxi Normal University global energy interconnection development and cooperation organization

Based on the micro-survey data of rural households in China’s Loess Plateau and Qinba Mountains, this paper empirically examines the poverty reduction effect and mechanism of adaptation to climate change. The research conclusions show that the adaptation actions can significantly reduce the poverty vulnerability of farmers, especially the future incidence of poverty in agricultural or poor households to a greater extent, which is characterized by a “pro-poor” *** actions can reduce poverty from two aspects: decreasing the expected income volatility(loss mitigation effect) and increasing the expected income level(opportunity effect), and the former is stronger than the latter. In the post-2020 period, China should enhance policy support in rural areas to adapt to climate change, improve the resilience of farmers’ livelihoods and climate change resilience of rural areas, and promote sustainable poverty reduction.
