The 2022 2nd International Conference on Power Grid Systems and Green Energy (PGSGE 2022) was planned to be held on January 07-09, 2022 in Xiamen, China. Due to the impact of COVID-19, many communities from all over the world were under strict health measures and strict travel restrictions, and participants of 2022 2nd International Conference on Power Grid Systems and Green Energy (PGSGE 2022) also meet with the difficulty of travel restrictions. For communities, if our conference was not held in a virtual form, it would add huge work on traffic system, Exit-Entry system, medical system, etc., which is quite a serious issue, to actively respond to the call of the government, to strengthen the protection work, to effectively reduce people gathering and prevent COVID-19, considering the situation that most of the authors would like to publish their articles and make academic communications as scheduled, PGSGE 2022 was held on-line instead of postponing the conference. It was a challenge, not only to the organizers, but also to the participants who were delivering their speeches using videoconference tools, under different time zones.It is a comprehensive conference which focuses on Power Grid Systems, Power Engineering and Energy Storage and Energy. The main objective of PGSGE 2022 is to address and deliberate on the latest technical status and recent trends in the research and applications of Power Grid Systems and Green Energy. PGSGE 2022 provides an opportunity for the scientists, engineers, industrialists, scholars and other professionals from all over the world to interact and exchange their new ideas and research outcomes in related fields and develop possible chances for future collaboration. The conference also aims at motivating the next generation of researchers to promote their interests in Power Grid Systems and Green Energy.The conference brings together about 90 leading researchers, engineers, and scientists in the domain of interest from China, Malaysia and Australia. The conference model was divided into two parts, including keynote presentations and online discussion. In the first part, each keynote speakers were allocated 30 minutes to present their talks via Zoom.
