The independent energy storage power stations are expected to be the mainstream, with shared energy storage emerging as the primary business model. There are four main profit models. Other ancillary services: Providing ancillary services such as black-start and voltage regulation.
As fossil fuel generation is progressively replaced with intermittent and less predictable renewable energy generation to decarbonize the power system, Electrical energy storage (EES) technologies are increasingly required to address the supply-demand balance challenge over a wide range of timescales.
Energy storage is an important link for the grid to efficiently accept new energy, which can significantly improve the consumption of new energy electricity such as wind and photovoltaics by the power grid, ensuring the safe and reliable operation of the grid system, but energy storage is a high-cost resource.
The reason is that the scheme for local storage of surplus electricity does not consider that the excess energy does not participate in the power coordination of the external grid.
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.
The energy storage configuration should be converted to independent operation mode through technological upgrading. This transformation enables the original abandoned output power from the wind and solar can be stored and thereby increasing revenue through the consumption of otherwise discarded electricity.
