Energy storage has a wide range of applications in various application scenarios of power systems and has been verified in engineering examples. The role of energy storage in the power generation side is mainly to improve economic and social benefits.
Through shared energy storage and other energy storage business models, the application scope of energy storage on the power generation side, transmission and distribution side, and user side will be blurred. And many application scenarios can realize the composite utilization of energy storage according to demand.
Energy storage can adjust the output reactive power and then adjust the voltage of the entire line to dynamically compensate the power grid [28, 29]. The energy storage system is installed upstream of the blocked line. Store the energy that cannot be transported by the line in the energy storage device when the line load exceeds the line capacity.
Shared energy storage not only increases the amount of new energy power generation and eases the pressure on local power grids for peak regulation, but also assists the energy storage power station to achieve a revenue-generating model that obtains rental fees and profits from increased power generation.
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.
