Special Session VIII
Power Quality and High-quality Power Supply
With the large-scale integration of new energy into the grid and the accelerated construction of a new power system, power quality and high-quality power supply have become a solid foundation for ensuring energy security and supporting industrial upgrading. Driven by the "dual carbon" goals, the volatility, intermittency, and nonlinear characteristics of a high proportion of renewable energy sources have led to frequent issues such as grid frequency fluctuations, voltage, and harmonic disturbances. Moreover, the popularization of digital and intelligent electricity consumption scenarios has further amplified the demand for high-quality power supply. Currently, power grid companies are achieving the optimization and improvement of power quality through means such as customized power quality management equipment, energy storage compensation, and demand response, effectively alleviating the impact of new energy grid connection on power quality. However, the decentralized access and random fluctuations of a large number of new sources and loads, as well as the poor governance effect of the traditional point-to-point approach, pose significant challenges in dynamic power quality perception, assessment of the carrying capacity for new energy access, and coordinated control of power quality by multiple types of flexible resources. These factors still restrict the realization of the goal of high-quality power supply in the power grid. In order to deepen industrial transformation and promote the development of new productive forces, this column focuses on the technological innovation of power quality optimization and improvement, gathers cross-disciplinary research achievements, and provides theoretical and technical support for the construction of a safe, efficient, and green new power system. The topics include but are not limited as below:
The topics of interest include, but are not limited to:
• Simulation and optimization technologies for power quality in new power systems
• Power quality sensing and measurement technologies under the large-scale integration of new energy sources

Fund/General Program/Youth Program). She has been authorized 54 Chinese and
American invention patents, among which 5 have been transferred for
implementation licenses (with transfer of research results value of 3 million
yuan). She has won 5 provincial - level scientific and technological progress
awards, including 1 first - class award of the Sichuan Provincial Scientific and
Technological Progress Award (ranked 1st). She has also won 10 industry and
society scientific and technological progress awards, including 1 first - class
award of the Power Science and Technology Progress Award of the Chinese Society
for Electrical Engineering (ranked 1st), 3 first - class awards of the Electric
Power Science and Technology Innovation Award of the China Electricity Council
(ranked 1st/ranked 3rd/ranked 8th), and 2 gold awards of the Invention
Entrepreneurship Award of the China Invention Association (ranked 1st/ranked
3rd). She has been rated as an outstanding scientific and technological worker
in the power field by the Chinese Society for Electrical Engineering, and a
"Power of Electricity" science communication expert of the Chinese Society for
Electrical Engineering. She took the lead in formulating the most core national
standard in the power quality field, "Power Quality - Terms" (draft for
approval) (ranked 1st). As the fundamental program and foundation in the power
quality field, it supports the national power quality management, treatment
work, and industry development. She was the main writer of 2 international
standards in the power quality field, IEEE Std. 2938 - 2023 (ranked 2nd) and IEC
TR 63222 - 100: 2023 (ranked 8th), 7 national standards including GB/T 39227 -
2020 (ranked 2nd), and 6 industry standards including DL/T 2475.1 - 2022 (ranked
3rd). She serves as the vice - chair of IEEE P2938 and IEEE P3453. She has been
the guest editor - in - chief of special issues on power quality in journals
such as "Proceedings of the CSEE" and "Power Supply & Utilization" for 4 times.
