创建于05.29

1. Frequency Regulation and Ancillary Services on the Grid Side

Case 1: Thermal Power Plant Combined Frequency Regulation (Thermal Storage Frequency Regulation)

Quickly respond to grid frequency changes (in milliseconds) through energy storage systems, compensating for the slow response speed and low precision of thermal power units. For example, the McIntosh compressed air energy storage station in Alabama, USA, improves efficiency by adding a heat exchanger to provide frequency regulation services to the grid.

Case 2: Independent Energy Storage Participates in Secondary Frequency Regulation

Large-scale energy storage power stations on the grid side (such as the Shandong Feicheng salt cavern compressed air energy storage power station) can provide functions such as peak shaving, phase adjustment, emergency response, and black start for the grid. For example, they can quickly release electrical energy to stabilize frequency during grid failures.

2. Remote areas and off-grid power supply

Case 1: Amazon Rainforest Off-Grid Microgrid

Using solar energy + energy storage to supply power to remote communities (such as the Huatacondo community in Brazil), addressing the issue of populations without electricity, and supporting schools, healthcare, and local economic development.

Case 2: Island Microgrid

China has deployed off-grid microgrid systems on islands in the South China Sea, coordinating photovoltaic, wind power, and energy storage to achieve self-generated and self-used power for the islands, providing stable electricity for personnel and equipment stationed on the islands (such as the Zhoushan Islands demonstration project).

3. Transportation Infrastructure

Case 1: Urban Rail Transit Energy Storage

Flywheel energy storage is used for regenerative braking energy recovery in subways. For example, the Beijing subway uses a flywheel energy storage system to recover the electrical energy during train braking for use in starting other trains, achieving an energy-saving efficiency of over 30%.

Case 2: Port Shore Power Replaces Auxiliary Generator Power

Shanghai Yangshan Port deploys lithium battery energy storage systems to provide clean shore power for docked vessels, reducing pollution from diesel generators, with annual CO₂ emissions reduced by over ten thousand tons.

4. Agriculture and Irrigation

Case: Solar Energy + Smart Irrigation Energy Storage

The agricultural area construction in Niger, Africa, utilizes a "photovoltaic + energy storage" system to charge during low electricity price periods and drive smart irrigation equipment during peak electricity usage, reducing electricity costs. For example, a certain project reduced diesel usage by 80% and improved water-saving rates by 25%.

5. Ocean and Ship

Case 1: Ship Energy Storage System

Freedom Won launches the Ocean Series energy storage products (IP65 protection level), suitable for yachts and deep-sea fishing boats, supporting stable power supply in high humidity environments, replacing traditional fuel generators.

Case 2: Offshore Oilfield Island Power Grid

In a certain oil field in the South China Sea, a tiered lithium battery system is deployed to smooth out load fluctuations on the drilling platform, reduce diesel consumption, and save over 5 million yuan in fuel costs annually.

6. Communication and Emergency Backup

Case 1: Africa 5G Base Station Energy Storage

Nigeria uses "lithium battery + photovoltaic" to power base stations in remote areas, achieving peak shaving and valley filling through intelligent scheduling, resulting in a 40% reduction in base station operation and maintenance costs.

Case 2: Hospital Emergency Energy Storage Power

A hospital in Berlin, Germany, is equipped with a perfluorohexane fire extinguishing system's energy storage cabinet, providing 48 hours of backup power during grid interruptions to ensure continuous power supply to the operating room and ICU.

7. Public Places and Urban Services

Case: Seasonal Energy Storage for Urban Heating

Copenhagen, Denmark utilizes underground rock layer heat storage technology to store excess heat in summer and provide heating in winter, covering 30% of the city's heating demand and reducing seasonal energy waste.

💡

Summary

Energy storage systems demonstrate diversified application value in fields such as grid frequency regulation, off-grid power supply, transportation, agriculture, marine, communication, and urban public services, addressing specific scenarios' energy supply, efficiency improvement, and environmental protection needs through technological adaptation.
