Summary
The above case demonstrates the core value of industrial and commercial energy storage:
1. Peak-valley arbitrage: Utilize the price difference to achieve electricity cost savings (Case 1, 2, 6).
2. Demand Management: Reduce transformer demand electricity costs (Case 1).
3. Photovoltaic consumption: Increase self-consumption rate, reduce low-priced grid connection of surplus electricity (Case 2, 5).
4. Backup power supply: Ensure production continuity during power restrictions/outages (Case 4).
5. Policy subsidies drive: Local subsidies accelerate investment recovery (Case 2).
