Energy storage solutions for construction sites (with difficult power distribution)

By adopting the ACADIE NEW ENERGY (ANE SINY) integrated air-cooled energy storage system, both the power grid and the diesel generator set as well as the energy storage system supply power simultaneously at the moment of starting an impact load, reducing the impact during startup and thus minimizing the capacity of the power grid distribution or diesel generator set, saving costs. Meanwhile, the addition of energy storage enables the diesel generator set to operate smoothly at the optimal load state, enhancing its operational efficiency and saving fuel.

The cost of power distribution at construction sites is high. The current surge during the startup of impulse loads is 3 to 5 times that of normal operation. The traditional solution requires the power grid to be sized according to the maximum load of the equipment or to install a diesel generator, resulting in high costs. Moreover, the impulse loads at the construction site cause significant fluctuations in the operation of the diesel generator, resulting in low efficiency and high fuel consumption.

The ACADIE NEW ENERGY (ANE SINY) integrated air-cooled energy storage system is adopted. At the moment of starting under impact load, the energy storage system provides power, or the power is supplied by the grid, diesel generator, and energy storage system simultaneously. This reduces the impact during startup, thereby reducing the capacity of the power distribution grid or diesel generator, and saving costs. At the same time, the addition of energy storage enables the diesel generator to operate stably in the optimal load state, improving the operating efficiency of the diesel generator and saving fuel.

• Environmental Protection

  Replacing diesel generators has eliminated the high noise and carbon emissions during their operation.

• Reduce impact on the power grid from transient loads

  The energy storage system supplies power during the instant of starting transient loads, reducing the impact during startup.

• Save costs

  Save on distribution costs or the cost of the diesel generators.

• Save fuel

  The integration of energy storage enables the diesel generator to operate within the optimal load range, resulting in lower fuel consumption.

• Peak-valley arbitrage

  During normal operation, the energy storage system can adjust its power output according to the load conditions, thereby achieving peak-valley load balancing and engaging in the arbitrage of the price difference between peak and valley periods.

The integrated air-cooled battery power generation system adopts the All-In-One design concept, integrating the power distribution system, power conversion system, battery system, EMS system, temperature control system, and fire protection system. It has a small footprint and can be multi-cabinet and cabinet-connected to achieve larger capacity expansion. The battery part of the system adopts a four-level fire protection and safety design, ensuring the highest system safety; the power conversion part uses the third-generation SiC components, with an energy conversion efficiency 1% to 2% higher than that of conventional systems, bringing higher economic benefits to the operator and shortening the investment recovery period. The energy storage system features a 200% load shock resistance characteristic, capable of supporting up to 1.5 times overload for 5 consecutive seconds without voltage waveform distortion. and can operate continuously for 5 seconds under 2 times overload.This solution is applicable to customers who originally used diesel generators as the voltage source and have the need to save costs and reduce noise. It is particularly suitable for power supply to motor-type equipment such as cranes, hoists, winches and mixers on construction sites, thereby achieving energy conservation, environmental protection and zero carbon emissions. Meanwhile, this battery generator can take advantage of the peak-valley difference of the power grid to reduce operating costs and improve economic benefits (charging at night and discharging during the day).
