Peak-valley arbitrage energy storage solution
Summary: Empower commercial and industrial energy storage "peak-valley arbitrage" with core PCS, charge during valley hours and discharge during peak hours, significantly reducing electricity costs.
Solution Overview
For industrial and commercial users subject to time-of-use electricity pricing, energy storage enables peak-valley arbitrage through "charging at low prices and discharging at high prices," reducing overall electricity costs.
Key Points
- Peak-valley arbitrage: charge during valley periods, discharge during peak periods
- High cycle efficiency PCS
- Long-life battery cells support two charge-discharge cycles per day
- Reduce energy charges and demand charges
Applicable Scenarios and Challenges
High peak electricity prices and high demand charges result in electricity costs accounting for a large proportion of operating costs; significant room exists for optimizing demand charges and power factor adjustment charges.
VGRID System Composition
- Power Conversion System (PCS): High-efficiency bidirectional conversion, ensuring high cycle efficiency and grid-friendly operation.
- Static Transfer Switch (STS): Protection switching at the grid connection point, ensuring safe isolation.
- Battery Energy Storage System (BESS): Long-life battery cells, supporting two charge-discharge cycles per day.
- Energy Management System (EMS): Develops charge-discharge strategies based on electricity price curves and demand forecasts.
- Microgrid Power Station (MPS): Factory-level AC cabinet, integrating metering and fire protection interfaces.
Core Value
- Significant reduction in energy charges
- Demand management reduces demand charges
- Participate in demand response for additional revenue
- Clear and measurable investment payback period

FAQ
What mainly determines peak-valley arbitrage revenue?
The peak-valley price spread, cycle efficiency, and the local electricity pricing mechanism; the larger the spread and the more charge-discharge cycles, the higher the revenue.
Is the energy storage system lifespan sufficient?
Long-life battery cells are used together with EMS optimization of charge-discharge depth to ensure many years of economic cycling.
How many times can it charge and discharge per day?
Typically two charges and two discharges, determined by the price spread and the EMS strategy.
Is new power distribution required?
It is usually connected nearby to the grid-connection point, with integrated MPS/PCS, requiring minimal modification.
