Risks, challenges and strategies of power systems against the background of carbon neutrality

Abstract

Building a new power system with new energy as the main body is an important means of achieving the goal of carbon neutrality. Compared with the traditional power system, the new power system has great changes and challenges in its safety mechanism and balance mechanism. Based on this, this paper focuses on the changes in the characteristics, functions and technologies of the new power system from the three sides of the source network and load. On this basis, the challenges faced by the high proportion of new-energy power systems are summarized from six aspects: reliability, stability, economy, data intelligence, flexibility and synergy. Finally, corresponding countermeasures, solutions and suggestions are put forward for the challenges of reliability, stability, economy, data intellectualization, flexibility and synergy, which provide ideas for the power guarantee of the new power system.

Integrated Planning and Operation Dispatching of Source–Grid–Load–Storage in a New Power System: A Coupled Socio–Cyber–Physical Perspective

“…The new power system boasts a broader range of energy supply forms and incorporates highly intelligent and automated operational features compared to those of traditional power system. Nevertheless, its architectural complexity has increased [1], notably with the integration of storage into the traditional three-element structure of source-grid-load, thereby shaping the current framework of source-grid-load-storage [2,3].…”
