With the in-depth advancement of the "dual carbon" strategy

the high proportion of new energy integration into the power grid has brought about systemic challenges such as weakened inertia support

complex dynamic characteristics

and strong randomness on both the supply and demand sides. Traditional control methods have fundamental limitations in response speed

adaptability

and coordination. As the core support of the new power system

the digital power grid's multi-level coordinated control architecture provides a key path to address these challenges. Advanced control technology

as the core hub

has become a fundamental requirement for ensuring the safe and stable operation of the new power system. This paper focuses on two core challenges in the digital power grid: the full integration of new energy and the maintenance of power grid security and stability. It systematically reviews the research progress and applications of advanced control technology. In response to the strong nonlinear dynamic characteristics and coordination difficulties of massive heterogeneous devices in the new power system

advanced control technology has demonstrated significant value in overcoming the response lag and adaptability bottlenecks of traditional control. Using model- or data-driven paradigms can effectively improve system control accuracy

but it still faces common problems

such as insufficient generalization in complex scenarios and conflicts in multi-objective optimization. To meet the requirements of global resource collaborative response and millisecond-level decision-making

a "cloud-edge-device-chip" hierarchical control architecture has been proposed. The cloud-side stability control achieves millisecond-level safety boundary decision-making based on global situation awareness; the edge-side group control significantly improves response efficiency through dynamic aggregation of distributed resources; the device-side numerical control ensures precise voltage and frequency support for distributed energy; and the chip-side intelligent control breaks through the computing power bottleneck of embedded devices with miniaturized AI chips. Finally

based on technical bottlenecks and development trends

a future development path for hierarchical coordinated control is proposed

focusing on building a four-level closed-loop control system of "cloud-edge-device-chip" in the digital power grid and establishing a hierarchical optimization system to support a high-resilience

low-carbon digital power grid.
