(1) It can effectively improve the safety and power supply reliability of the power system. Utilizing the powerful “self-healing” function of the smart grid, it can accurately and quickly isolate faulty components and quickly restore the system to normal conditions with less human intervention, thereby improving the safety and reliability of system power supply.

(2) To achieve sustainable development of the power grid. Strong smart grid construction can promote technological innovation in power grids, and realize improvements in all aspects such as technology, equipment, operations, and management to meet the needs of the electricity market and promote scientific and sustainable development of power grids.

(3) Reduce the effective installed capacity. Utilizing the characteristics of large differences in power load characteristics in different regions of China, through intelligent unified scheduling, we can obtain network benefits such as peak shifting and peaking; at the same time, we can use the time-of-use price mechanism to guide users to reduce electricity consumption and reduce peak load, thus reducing the effectiveness Installed capacity.

(4) Reduce the cost of the system for generating fuel. Building a strong smart grid can meet the intensive development of coal-fired power plants and optimize the layout of China's power supply so as to reduce fuel transportation costs. At the same time, by reducing load peak-to-valley differences, it can increase the efficiency of thermal power units, reduce coal consumption, and reduce power generation costs.

(5) Improve the utilization efficiency of power grid equipment. First, by improving the power load curve, the peak-to-valley difference is reduced, and the utilization efficiency of power grid equipment is improved; secondly, the self-diagnosis capability is extended to extend the life of the power grid infrastructure.

(6) Reduce line loss. The strong smart grid based on the UHV transmission technology will greatly reduce the loss rate in the transmission of electric energy. Intelligent dispatching system, flexible transmission technology and real-time two-way interaction with users can optimize the distribution of the trend and reduce the line loss; at the same time, The construction and application of distributed power also reduce the network loss of long-distance power transmission.
