New energy has strong randomness, low controllability, and high security risks. The increasing of new energy has caused the traditional power system to face overall problems, requiring a series of technical support related to the new energy power system. The study first outlines concepts and basic features of the new energy power system, and then introduces three control and optimization methods of the new energy power system, including effective utilization of demand-side resources, large-scale distributed energy storage and grid integration, and source–network–load–storage integration. Faced with the problems of low power supply reliability, unbalanced distribution of new energy and power load, and insufficient power consumption which is produced by new energy, this paper puts forward methods such as vigorously developing energy storage technology, building a “low-carbon power technology development mechanism”, and building a “low-carbon power smart power utilization mechanism”, and proposes a number of recommendations for related policies.
