Customizable High Voltage Cascade Energy Storage System 6kV~35kV Multichannel Power Supply

Energy Storage for Frequency Regulation

• How it Works: This system connects to the grid (or a microgrid) to monitor power load changes in real-time. It uses supercapacitors to instantly release power when demand suddenly increases (supporting grid stability) and absorb power when demand suddenly drops (preventing voltage spikes).
• Benefit: Stabilizes the local power grid, boosting safety and reliability, especially for temporary or isolated systems. It offers fast response times, is energy-efficient, and environmentally friendly.
• Key Advantages:
  • Rapid Detection: Quickly (under 1 second) and accurately identifies sudden power surges or drops using an advanced algorithm.
  • Smart Compensation: Automatically stabilizes power during various load fluctuations (single, continuous, or random), minimizing impact on the grid.
  • Clean Grid Connection: Ensures smooth grid integration with very low electrical noise (current harmonics < 3%) using advanced power electronics.
  • Versatile: Also provides reactive power support and can function as a backup power source (off-grid mode) during outages.

Energy Storage for Peak Shaving

• Problem: High electricity demand during peak hours strains the power grid. This can lead to inefficiency, high operational costs, potential power shortages (especially during summer), and challenges integrating intermittent renewable energy sources (like solar and wind).
• Solution: Large-scale energy storage systems.
• How it Helps: Balances power supply and demand by storing energy when generation exceeds consumption (especially from renewables) and releasing it when needed. This improves overall grid stability and power quality.
• Application (Peak Shaving / Valley Filling): Store lower-cost electricity generated during off-peak hours ("valley" times) in batteries. Then, use this stored energy during high-demand peak hours.
• Benefits: Reduces strain on the grid during peak times and lowers electricity costs for end-users by shifting energy use away from expensive peak periods.

Advantages

• Battery cluster operates with all cells under control.
• High output waveform quality is achieved under low carrier frequency.
• System efficiency is improved by more than 3%.
• Grid dispatch is simplified with fast response speed.
• Power unit redundancy design extends fault-free operation time.
• Increased power leads to more significant cost advantages and emerging size benefits, along with a reduction in the number of primary switches for connection.
