When every line and every device in the power grid has a "digital avatar", the transformation towards digitalization has a vivid footnote. Digital twins are quietly changing the operation mode of the power grid and unlocking new possibilities for energy development.

Recently, the World Data Organization was established in China, which means that global data governance, circulation, and value mining have entered a new stage of institutionalized development. Digital twin is a technology that builds a physical object mirroring system in the digital space. Its core is to accurately reflect physical objects through real-time data, which is used for simulation, monitoring, prediction, and optimization. The establishment of the World Data Organization can provide a more comprehensive data foundation and rule guarantee for the development of digital twin and other intelligent technologies.

Digital twins assist in the transformation of the power grid

As a key measure to promote the digital transformation of the power grid, digital twins can achieve high fidelity mapping, real-time perception, and dynamic inference of the physical power grid in the digital space. Driving energy transformation with data and accelerating the deep integration of digital twins and modern power grids is the only way to seize the opportunities of the new round of technological revolution and industrial transformation.

Supporting source network load storage collaboration

The collaborative development of source network load storage cannot be separated from the strong support of digital twins. Currently, the large-scale integration of new energy into the grid, the extensive access of distributed resources, and the deepening of the coupling between source, grid, load, and storage have led to a continuous increase in the difficulty of optimizing resource allocation. The digital twin power grid integrates technologies such as artificial intelligence, advanced control, and intelligent sensing, which can more accurately judge the laws of new energy generation and load changes, optimize the operation mode and energy storage regulation strategy of the power grid, promote efficient interaction between source, grid, load, and storage, optimize scheduling, and provide guarantees for the high proportion of new energy access and high-level consumption.

In the construction of modern power grid engineering system, digital twins can play an important role. In the face of major tasks such as regional coordinated development, the development of the "Shage Desert" new energy base, and the construction of cross regional transmission channels, the construction of power grid projects needs to be planned and coordinated in advance. Digital twins can connect various aspects such as planning, design, and construction, promote efficient connection between engineering construction and system requirements, and promote the linkage between individual project construction and overall network optimization; Combining intelligent manufacturing and mechanized construction can also improve the safety, quality, and efficiency of engineering construction.

Improve the level of power grid operation and maintenance

Improving the intelligent operation and maintenance level of modern power grids can solve development problems with the help of digital twins. Currently, the scale of the power grid is constantly expanding, the grid structure is becoming increasingly complex, the types of equipment are becoming more diverse, and the operating mechanism of the power system is also becoming more complex. Digital twin promotes the deep integration of digital space and physical power grid, connecting the entire process of perception, analysis, decision-making, execution and feedback. By relying on dynamic mapping, simulation deduction and comprehensive analysis, it enhances the ability of state perception, trend judgment and risk disposal, and promotes the transformation of power grid operation and maintenance from "post disposal" to "pre warning and mid intervention".

With the continuous deepening of digital transformation, digital twins and artificial intelligence will work together to gather various types of data on a unified digital base, enhance situational awareness, risk identification, and collaborative decision-making capabilities, and provide support for intelligent planning, design, and construction of the power grid.
