[Introduction] In the face of energy scarcity and carbon reduction imperatives, the transition to clean energy centered on electricity is crucial. To achieve this, power system development must prioritize stability, automation and intelligence. Artificial intelligence (AI) technology is a key means to realize this goal. [Method] This paper introduced the carbon emissions of domestic and foreign power systems at first, and pointed out the difficulties and feasible solutions for low-carbon development of the power system in China on this basis. Then, the application and prospect of AI technology in power system development were discussed. [Result] In response to the transition to low-carbon and low-energy power systems, a series of low-carbon development routes, such as integration of capital and resources in the thermal power industry, low-carbon transition (such as the application of carbon capture technology), and promoting the consumption of and smooth replacement by clean energy, were proposed in this paper. It was also noted that AI technology will play a crucial role in automating, intelligentizing and optimizing power systems, with wide-ranging applications in power dispatching, relay protection, power equipment management, power system stability evaluation, and decision-making processes. [Conclusion] As third-generation AI technology continues to evolve and fourth-generation AI technology emerges, the application of AI technology in the power system will become increasingly widespread.

To explore the process of extraction and antioxidant activity of products from marine sponge, three influencing factors, ultrasonic temperature, ultrasonic time, and ultrasonic power were investigated respectively taking DPPH radicals scavenging rate of ethanol extracts from H. erectus as the response value, and the optimal ultrasonic-assisted extraction process was determined by Box-Behnken design. The extract obtained from H. erectus by the best ultrasonic-assisted process was detected for antioxidant activity, which included the scavenging effect on DPPH radicals, ABTS+• and •OH. The effects of the extract on viability of oxidative damage L02 cells and content of intracellular ROS were detected by constructing a cell model of H2O2 induced oxidative damage. The results showed that the optimized process conditions were as follows: Ultrasonic temperature was 57 ℃, ultrasonic time was 60 min, and ultrasonic power was 490 W. Under these conditions, the DPPH scavenging rate of the extract was 61.98%±1.52%, which agreed well with the predicted value of 62.16%. The extract showed good scavenging effects on DPPH radical, ABTS+• and •OH. The cell viability of treated groups was significantly higher than that of the model group (P
