Congratulations on Prof. Yu Juan's article "Reliability Assessment of Power-Gas Interconnection System with Electricity to Gas" being selected as "Top Academic Paper of China Quality Science and Technology Journal (F5000)"! It reflects the high influence and academic value of the research results in China.
Initiated by the Ministry of Science and Technology, F5000 aims to further promote the overall level of China's science and technology journals, better publicize and utilize China's excellent academic achievements, promote more scientific research results to the world, participate in international academic exchanges, expand international influence, and play a leading and exemplary role. F5000 is selected by the Institute of Scientific and Technological Information of China using a method of combination of scientific measurement indicators and peer review, in the selection of excellent academic papers among Chinese selected science and technology periodicals, in the form of long English abstracts, focusing on presenting and communicating the excellent academic papers in China. Through the cooperation with internationally important information service institutions and international publishing institutions, F5000 papers will be centrally linked and pushed to international counterparts. F5000 provides an efficient channel for the integration of Chinese-published papers, authors and Chinese academic journals into the international academic community, reflecting the high impact and academic value of the selected research results in China.
Professor Yu Juan's paper firstly addresses the problem that the system abandonment phenomenon and the operating characteristics of P2G devices are not considered enough in the existing system state analysis models, and proposes the energy flow model based on P2G devices and gas units, and the electricity/gas/heat load reduction optimization model considering wind power abandonment. Secondly, the existing reliability indexes are further improved, and the system-level reliability indexes of power/gas/heat deficiency expectation and wind abandonment expectation are established, as well as the equipment-level reliability indexes of P2G device utilization probability, capacity utilization rate and contribution coefficient are also established. Thirdly, on the basis of the established energy flow model, load reduction optimization model and reliability evaluation index, the reliability evaluation method of power-gas interconnection system including P2G is proposed by further considering various random factors such as component failure, electrical/gas/heat load and wind power. Finally, the effectiveness of the proposed method is verified by an example simulation. The content is novel and unique, so it is recommended.
