(1) Have a strong ability to optimize resource allocation. After the completion of my country's smart grid, it will form a strong receiving-end power grid and a sending-end power grid, and the power carrying capacity will be significantly strengthened, forming a "strong AC, strong direct" UHV transmission network, realizing large hydropower, large coal power, large nuclear power, large power. The cross-regional, long-distance, large-capacity, low-loss, and high-efficiency transmission of large-scale renewable energy has significantly improved the power exchange capacity between regions.

(2) It has a higher level of safe and stable operation. The security, stability and power supply reliability of the power grid will be greatly improved. There will be close coordination between the defense lines at all levels of the power grid, and the ability to resist emergencies and serious failures can effectively avoid the occurrence of large-scale cascading failures and significantly improve power supply reliability. Reduce power outage losses.

(3) Adapt to and promote the development of clean energy. The power grid will have control mechanisms such as wind turbine power prediction and dynamic modeling, low voltage ride-through and active and reactive power control, and rapid regulation of conventional units. Combined with the popularization and application of large-capacity energy technologies, the operation control capability of clean energy grid connection will be significant. upgrade to make clean energy a more economical, efficient and reliable energy supply method.

(4) Realize highly intelligent power grid dispatching. A horizontally-integrated and vertically-connected smart grid dispatching technology support system will be built in an all-round way to realize online intelligent analysis, early warning and decision-making of the power grid, as well as efficient regulation of various new generation and transmission technologies and equipment and lean control of AC/DC hybrid power grids.

(5) To meet the service requirements of new power users such as electric vehicles. A complete electric vehicle charging and discharging supporting infrastructure network will be formed to meet the development needs of the electric vehicle industry, adapt to the needs of users, and achieve efficient interaction between electric vehicles and the power grid.

(6) Realize efficient utilization of power grid assets and full life cycle management. It can realize the overall management of power grid facilities in the whole life cycle. Through smart grid dispatching and demand-side management, the utilization hours of grid assets have been greatly increased, and the utilization efficiency of grid assets has been significantly improved.
