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.
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.
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.
The 101 MW/202 MW•h grid side energy storage power station in Zhenjiang, Jiangsu Province, which was put into operation on July 18, 2018, is currently the largest grid side energy storage power station project in China and the world's largest electrochemical energy storage power station.
The power grid company improves transmission efficiency by connecting or building wind farms, constructing grid-side energy storage, upgrading the grid, and assisting users in energy conservation, carbon offsetting, etc. to achieve zero carbon goals.
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.
