6 FAQs about [Analysis of energy storage mechanism of China Southern Power Grid]
What are source grid load storage coordination measures?
Source grid load storage coordination measures. When energy storage is involved in market operation, it has certain time and space rules.
What are energy storage capacity configuration schemes?
According to their characteristics, two energy storage capacity configuration schemes are set up, including local storage of surplus electricity and local balance of surplus electricity for Internet access.
What is the difference between energy storage capacity configuration and online storage?
In the three scenarios, with the distinction between the two methods of energy storage capacity configuration, it is clear that the storage capacity of the energy with the surplus power online presents far less than with surplus power offline in local equilibrium.
What is the difference between power grid and energy storage?
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.
