The power grid side connects the source and load ends to play the role of power transmission and distribution; The energy storage side obtains benefits by providing services such as peak cutting and valley filling, frequency, and amplitude modulation, etc.
Due to the important application value of grid side energy storage power stations in power grid frequency regulation, voltage regulation, black start, accident emergency, and other aspects, attention needs to be paid to the different characteristics of energy storage when applied to the above different situations.
For each typical application scenario, evaluation indicators reflecting energy storage characteristics will be proposed to form an evaluation system that can comprehensively evaluate the operation effects of various functions of energy storage power stations in the actual operation of the power grid.
Due to factors such as high prices of energy storage devices and imperfect market models, China's grid side energy storage projects are currently in their early stages, with limited engineering applications and a lack of evaluation methods of the actual operational effectiveness of power stations from multiple perspectives.
Source grid load storage coordination measures. When energy storage is involved in market operation, it has certain time and space rules.
The third part which is about Power system considerations for energy storage covers Integration of energy storage systems; Effect of energy storage on transient regimes in the power system; and Optimising regimes for energy storage in a power system.
