Sunshine Samsung energy storage system helps western photovoltaic power plants solve the problem of "abandoning light"

The problem of abandonment of light has led to a significant reduction in the investment income of photovoltaic power plants, which has long become a "heart disease" for photovoltaic investors, and in some areas, such as Gansu and Xinjiang, the annual abandonment rate of photovoltaic power plants has exceeded 30%
in 2015.
In order to cope with the problem of curtailment of light, Sunshine Samsung proposed the solution of connecting energy storage systems on the photovoltaic DC side for the first time in the world, and successfully applied it to the 100MW photovoltaic power station
in Suzhou Zhongkang and Jinchang, Gansu.
At present, the project has completed the commissioning work and is running smoothly on the grid
.

Sunshine Samsung provided a full set of design solutions for the project, including 2 sets of Sunshine Samsung PowCube 550 energy storage system, which adopts a 20-foot container integration design, each container integrates 550kWh Samsung ternary lithium battery, DC converter, BMS, intelligent temperature control, automatic fire protection, power distribution, communication and other complete equipment, and adopts DC side access scheme
.
The so-called DC side access means that the energy storage system
is connected in parallel at the DC bus end of the photovoltaic module and the photovoltaic inverter without changing the original equipment and configuration of the existing photovoltaic power station.

The energy storage system deposits excess power into the battery near the limited power line, sends out the stored power during a slightly idle time of the power grid, and cycles charging and discharging once a day, which has the following advantages: First, there is no need to re-declare the grid-connected procedures, and the battery charging can be automatically and flexibly controlled with the limited power condition
.
Second, there is no need for new transformers and energy storage inverters, and the use of
cables is reduced.
Third, using high-energy density Samsung ternary lithium battery and patented air duct design and temperature control system, the battery life cycle is long, and the number of 100% DOD cycles exceeds 6000 times
.
Fourth, it adopts a standard container design, which can be moved and recycled in different limited power stations
.
Fifth, the energy storage system can flexibly configure battery capacity according to the emission restriction situation, and completely solve the problem
of emission limiting.
The energy storage system can also adjust the smoothness of the output of the photovoltaic power station through the energy distribution algorithm, improve the stability of the photovoltaic power station, and at the same time greatly improve the accuracy of optical power prediction through the flexible control of the output power of the photovoltaic power station, make the power station more intelligent, and improve the friendliness of the power grid, and the energy storage system is expected to feed 400,000 kWh
per year.
