Industrial and commercial energy storage applications typically involve broader energy management and optimization to enhance efficiency and reduce costs. Below are the main classifications of industrial and commercial energy storage applications:
1. Grid Peak Shaving and Frequency Regulation
Peak Shaving: Stores electricity during low-cost periods (typically at night) and releases it during high-cost peak hours (such as daytime peaks) to reduce electricity expenses. It also serves as a backup power source, ensuring business continuity during grid failures or outages. Additionally, during peak demand periods, energy storage systems can discharge stored power to alleviate grid stress.
Frequency Regulation: Energy storage systems can quickly respond to fluctuations in grid frequency, maintaining stable grid operation.
2. Renewable Energy Integration
Output Smoothing: Stores excess renewable energy (such as wind and solar) to mitigate fluctuations in energy generation.
Load Shifting: Stores renewable energy during low-demand periods for use during peak hours.
3. Commercial and Industrial Applications
Peak Demand Reduction: In commercial buildings, energy storage systems supply power during peak pricing periods, lowering energy costs.
Backup Power: Ensures business continuity by providing emergency power during outages.
4. Microgrids and Distributed Energy Systems
A microgrid is a localized generation and distribution system that can operate independently or in parallel with the main grid. In industrial and commercial settings, energy storage is a key component of microgrids, balancing the intermittency of renewable energy sources (such as wind and solar) to ensure stable and reliable power supply.
Off-Grid Operation: Supports microgrid independence when the main grid is unavailable.
Energy Efficiency Improvement: Combining renewable energy with storage enhances overall energy efficiency.
5. EV Solar-Storage Charging Stations
This model integrates solar power generation, energy storage systems, and EV charging facilities. Surplus solar energy is stored for later use, reducing reliance on the grid and enhancing renewable energy utilization.
Load Balancing: Supplies additional power during peak charging periods, reducing grid stress.
Renewable Energy Integration: Uses solar or other renewable sources to power EV charging stations.
6. Backup Power and Temporary Applications
Emergency Power Supply: Ensures uninterrupted operations for critical facilities and production lines during grid failures.
Temporary Power Supply: Provides electricity for construction sites, outdoor events, and other temporary scenarios.
Disaster Response: Enables rapid deployment of power during natural disasters and emergencies.
