For the safe and stable operation of the power grid, due to the instability of the new energy power supply, the grid-connected power generation system without energy storage will have many adverse effects on line power flow, system protection, economic operation of the grid, power quality and operation scheduling. In this case, the role of energy storage is reflected. First, it is conducive to ensuring stable power supply in extreme weather such as high temperature and cold wave; Second, it is conducive to increasing the safety margin of the power system and solving the problem that the new energy power generation cannot provide effective moment of inertia, short circuit capacity and frequency modulation capacity; Third, it is conducive to improving the utilization rate of new energy and supporting the efficient use of a high proportion of new energy.
