In a laser welding factory in the Netherlands, the demand for electricity is always high. The laser welding machines, motors, transmission devices and other equipment in the factory operate almost around the clock. These equipment are particularly dependent on a stable and sufficient power supply. Especially when starting up, motor loads will instantly increase the power demand. Since the power grid in the area where the factory is located is only 50kW, it is far from meeting the power demand during peak hours. Especially in the case of a sudden increase in load, the power grid cannot respond in time, resulting in problems with equipment operation and sometimes even shutdowns.
Impact of power grid restrictions on production
As the scale of the factory continues to expand, the demand for electricity is increasing, and traditional power grid supply can no longer provide sufficient power support. Especially when laser welding and motor equipment are running, the instantaneous power demand often greatly exceeds the supply capacity of the power grid, and the response speed of the power grid is far from meeting these sudden power demands. This makes the factory often encounter the problem of insufficient power supply when performing laser welding, cutting and other processes. In severe cases, it may even cause equipment shutdown and production delays, affecting the overall production efficiency and the normal operation of the equipment.
When the factory’s laser cutting machine or electric equipment is started, the instantaneous power demand often far exceeds the 50kW power grid limit. At this time, the power response of the power grid becomes slow, resulting in voltage fluctuations and even power supply interruptions. Since the startup of motor-type equipment requires a fast and large amount of power supply, this delayed power supply seriously affects the production efficiency of the factory and even leads to production stagnation.
Solution: Dynamic capacity expansion of energy storage system
In order to deal with the problems caused by the bottleneck of the power grid, the factory management team decided to introduce SCU’s energy storage system. SCU provided the factory with a 645kWh/300kW 10ft energy storage container, which is designed to solve the problem of insufficient power grid through dynamic capacity expansion.
When the factory is operating normally, the factory is powered by the mains, but once the load demand exceeds 50kW, the excess power is supplemented by the SCU energy storage system. The energy storage system can respond quickly when the load suddenly increases, switching from the grid-connected standby state to the discharge mode. Crucially, the energy storage system has a very short response time and can provide the required additional power in just 1 second.
Advantages and benefits of SCU energy storage system
The SCU energy storage system has played a vital role in the application of the Dutch laser welding plant. Through its excellent technical advantages and significant economic benefits, it has helped the factory solve problems such as insufficient power grid, load fluctuations and unstable power supply. The specific advantages and benefits are as follows:
- 1s fast response
The SCU energy storage system acts as a “battery buffer” when the power grid cannot respond quickly, helping the factory to cope with instantaneous peaks in power demand. Especially when motor loads are started or running, the energy storage system can quickly provide instantaneous power, ensuring the smooth operation of the equipment and avoiding downtime or equipment failure caused by power fluctuations or shortages.
- Small footprint and easy installation
The compact design of the SCU energy storage container makes it very small in the factory, which can make full use of the limited factory space and improve space efficiency. The modular design makes its installation process simpler and faster, without the need for complex infrastructure construction. The factory can complete the system deployment in a short time to ensure that production is not affected.
- Significant economic benefits
The energy storage system helps the factory optimize electricity costs and improve overall production efficiency by reducing the additional costs caused by power fluctuations. When the power demand is low, the mains can be used to supply power, reducing the discharge frequency of the energy storage system. When the power demand increases suddenly, the energy storage system can provide additional power support in time, avoiding additional grid costs.
Conclusion
The SCU energy storage system not only solves the power bottleneck faced by the Dutch laser cutting plant under high load and instantaneous power demand but also provides the factory with an efficient and stable power supply solution. The dynamic capacity expansion capability of the energy storage system helps the factory to seamlessly connect the power shortage of the power grid, ensure the continuous and stable operation of the production line, and further improve the factory’s production efficiency and the economic benefits of power use. The introduction of the SCU energy storage system marks a solid step for the factory in facing the challenges of modern industrial electricity consumption and also provides a sustainable development solution for future industrial energy management.
