China's first MWh echelon energy storage system was successfully put into operation

Recently, the first MWh echelon energy storage system in China, led by Shanghai Xuda New Energy, was successfully connected to the big data platform
of State Grid Jiangsu Electric Power Company.
The operation of the system is equivalent to building a reservoir for the distribution network system on the user side, and the technology based on the decommissioned power battery has created a milestone in the era of low-cost lithium battery energy storage, realized the commercial promotion value of energy storage, and the echelon utilization energy storage system has become the user-side energy storage system
with the most economic investment value and large-scale promotion foundation.

With the social and economic development and productivity improvement, the intensity of electricity consumption in the industrial sector has gradually increased, and the difference between power supply and demand in time and space has become more and more, which has brought great pressure
to the power supply system.
Coupled with the continuous increase in the proportion of new energy power generation, a large number of fluctuating wind power generation and photovoltaic power generation are integrated into the traditional power grid, so that the power grid is subject to huge current impacts, resulting in grid frequency deviation, voltage fluctuation and flicker and other problems
.
The power grid company collects and dispatches the power consumption of various regions and equipment by building a big data platform, and regulates the power grid through equipment and platforms to ensure the stable operation of the power grid and the security
of power supply.

The progress of battery energy storage technology and the gradual reduction of cost and the maturity of the business model on the demand side have gradually made the application value of energy storage system in the power system gradually appeared: with its rapid power regulation and the characteristics of both supply and storage capacity, it has played a greater role in smoothing intermittent energy power fluctuations, shaving peaks and filling valleys, improving voltage quality and providing backup power, which is the key to the distribution network to achieve flexible regulation of widely accessed distributed energy resources and optimal operation of the network
.

It is understood that the MWh echelon energy storage system is composed of 9 sets of 20kW/122kWh energy storage basic units connected in parallel, a total of 180kW/1.
1MWh, taking the lead in realizing the commercial operation of echelon energy storage, thereby exploring a set of technology + commercial profit model and opening a new era
of commercial energy storage.
Its successful operation marks that the cost of lithium battery energy storage system has entered a new era of 1 yuan / Wh, and the user-side energy storage application has truly had commercial promotion value
