2.2MW/5.1MWh Peak Shaving And Valley Filling Project
Share:
In the beverage factory, 22 units of Galaxy 233L-AIO-2H have been deployed. These units enable the factory to perform energy arbitrage by charging during low-cost valley periods and discharging during peak price periods. This strategy maximizes cost savings and optimizes energy usage.
Technical Highlights
- The 2.2MW/5.1MWh LFP battery system has a modular, scalable architecture. It provides a cycle life of over 6000. The system supports seamless on/off-grid switching and responds quickly to industrial load changes.
- An intelligent EMS monitors real-time electricity prices and site load. It dynamically controls charging and discharging based on SoC, PV forecasts, and tariff signals. This helps maximize economic returns.
- Containerized The system uses a containerized and pre-integrated design. This allows plug-and-play installation and rapid commissioning. It can also be easily scaled or relocated to meet future energy needs.and pre-integrated design allows for plug-and-play installation, rapid commissioning, and easy scalability or relocation based on future energy needs.
We are committed to providing you with the best service possible.
Operation Strategy
- The system charges during midday when electricity prices are negative or PV generation exceeds demand. This enables cost-free, or even profitable, energy storage. It also helps prevent PV curtailment.
- Stored energy is discharged during high-tariff periods, typically in the evening. This reduces grid consumption and lowers electricity bills. The system achieves this through time-of-use arbitrage.
- The EMS actively monitors load profiles. It helps shave consumption peaks and reduces demand charges. The system also stabilizes grid interaction.
- The system stores surplus solar energy. It then uses this energy during non-generation hours. This approach significantly increases the facility’s PV self-consumption rate and green energy usage.
- All operations are optimized by the EMS. It uses real-time electricity prices, load forecasts, SoC, and PV generation trends. This ensures maximum economic and operational efficiency.
