The 2021 International Conference on Power Electronics and Power Transmission (ICPEPT 2021) was held on October 15-17, 2021 in Xi’an, China. ICPEPT 2021 is to bring together innovative academics and industrial experts in the field of Power Electronics and Power Transmission to a common forum. The primary goal of the conference is to promote research and developmental activities in Power Electronics and Power Transmission and another goal is to promote scientific information interchange between researchers, developers, engineers, students, and practitioners working all around the world. The conference will be held every year to make it an ideal platform for people to share views and experiences in Power Electronics and Power Transmission and related areas. The conference model was divided into two sessions, including oral presentations and keynote speeches. In the first part, some scholars, whose submissions were selected as the excellent papers, were given 15 minutes to perform their oral presentations one by one. Then in the second part, keynote speakers were each allocated 30-45 minutes to hold their speeches. More than 100 participants attended the meeting. There were over 20 experts and scholars in the area of Power Electronics and Power Transmission representing different famous universities and institutes around the globe to form Conference Committees. In the keynote presentation part, we invited three professors as our keynote speakers. The first keynote speakers, Assoc. Prof. Jinsong Tao, from School of Electrical Engineering and Automation, Wuhan University, China was invited to present his talk Operation Mode Analysis and Coordinated Control Strategy Research of Multi-terminal Network with DC Microgrid. Assoc. Prof. Sohrab MIRSAEIDI, from Beijing Jiaotong University, China was our second keynote speakers. He presented a talk: Improvement of Capacitor-Commutated-Converter-Based and Fault-Current-Limiting-Based Commutation Failure Prevention Approaches in HVDC Transmission Networks. In this talk, the structure of an improved Controllable Commutation Failure Inhibitor (CCFI) is presented which obviates the main drawbacks of the existing capacitor-commutated-converter-based and fault-current-limiting-based strategies. Assoc. Prof. ANWAR ALI, from Zhejiang Sci-Tech University, China as our finale keynote speakers. He delivered a speech: Design and Development of a Small Satellite Subsystems-AraMiS-C1. We are glad to share with you that we received lots of submissions from the conference and we selected a bunch of high-quality papers and compiled them into the proceedings after rigorously reviewed them. These papers feature following topics but are not limited to: 1. Power Electronic Technology. 2. Electric Power System. All the papers have been through rigorous review and process to meet the requirements of International publication standard. We are really grateful to the International/National advisory committee, keynote speakers, session chairs, organizing committee members, student volunteers and administrative assistance of the management section of University, including accounts section, digital media and publication house. Also, we are thankful to all the authors for contributing a large number of papers in the conference, because of which the conference became a story of success. It was the quality of their presentations and their passion to communicate with the other participants that really make this conference series a great success. The Committee of ICPEPT 2021 List of Committee members are available in this pdf.

Abstract A novel control strategy of synchronous compensators and converters is proposed to increase the ability of line commutated converter (LCC) based HVDC systems to successfully recover from commutation failures (CFs). The dynamic var support is one of the most important factors, which impact the commutation process. Many synchronous compensators have been implemented to enhance the transient voltage stability for improving the CF recovery performance. However, the traditional automatic voltage regulator (AVR) of synchronous compensator may not be suitable for the commutation voltage support, because the transient var demand of converters during the CF recovery is neglected. In our work, the voltage control will be adaptively adjusted, depending on the state of converters. Case studies based on simulations in PSCAD/EMTDC show that the proposed strategy can improve the performance of fault recovery from CF.
