Ten Application Scenarios Of Energy Storage Projects

Traditional industrial parks have many equipment, which have the characteristics of high power consumption, long-term high load, and high energy consumption of equipment. In order to achieve the carbon reduction goal, renewable energy is used in large quantities in smart parks, but due to its instability, it will lead to insufficient or excessive power supply. At this time, energy storage systems are needed to adjust the supply and demand levels.

In the "smart park + energy storage" mode, the energy storage system can collect excess electricity such as solar energy and wind energy, and then supply it to the power grid during the main power consumption time. This not only stabilizes the power grid, but the energy storage system can provide backup power to the power grid in an emergency to ensure the normal operation of the park. In addition, industrial parks have a higher electricity price difference, which is suitable for peak-valley arbitrage of energy storage projects.

The integrated implementation plan of energy saving-energy storage-charging for commercial complexes is a comprehensive solution. By adopting energy-saving technologies and equipment, the energy consumption of commercial complexes is reduced; distributed new energy power stations are installed in commercial complexes, and electric energy is stored through energy storage equipment for commercial entities to use, thereby reducing dependence on traditional energy.

In addition, through energy storage equipment, charging piles can also be set up in parking lots, underground garages and other places of commercial entities to provide charging services for new energy vehicles.

Under the implementation of the global low-carbon strategy, low-carbon data centers will be the future development trend. "Renewable energy + storage integration + virtual power plant" is one of the ways for data centers to achieve carbon neutrality. Through digital and intelligent technologies, distributed energy, energy storage, and load are deeply integrated.

By establishing the aggregation effect of the upper platform of the virtual power plant, the data center load, renewable energy power supply, and energy storage become an organic whole, achieving a self-generated and self-managed energy autonomous domain in the region, and truly realizing a carbon-neutral data center. In this process, the energy storage system improves the economy of data center power operation and enhances the power supply reliability of the data center through mechanisms such as peak shaving and valley filling and capacity allocation. While low-carbon energy saving, it can effectively prevent accidental power outages in the data center from causing data loss and improve the safety and stability of the power supply system.

With the rapid development of the new energy vehicle industry, the demand for charging is also growing synchronously. At present, there is still a huge gap in the charging pile market. As a new attempt at green economy, the "photovoltaic storage and charging integrated charging station" has broad development prospects.

The photovoltaic storage charging station integrates multiple technologies such as photovoltaic power generation, large-capacity energy storage batteries, and intelligent charging piles. It uses the battery energy storage system to absorb valley electricity and support fast charging loads during peak periods to supply green electricity for electric vehicles. At the same time, it is supplemented by the photovoltaic power generation system to achieve auxiliary service functions such as peak shaving and valley filling, effectively reducing the peak-valley difference of the fast charging station load and effectively improving the system operation efficiency.

In order to meet the growing number and electricity demand of 5G base stations, and to reduce resource waste, the electrochemical energy storage system has become a suitable choice for the backup power supply of 5G base stations with its flexible, intelligent and efficient technical characteristics.

The 5G base station storage uses intelligent peak shifting, charging during idle time and discharging during busy time, which well solves the pain point that the construction of 5G base stations cannot be smoothly promoted due to power supply problems, and is conducive to vigorously promoting the implementation of 5G base stations and the development of 6G technology.

More and more families are beginning to install photovoltaic power stations as a supplement to energy consumption or a source of electricity bill income. The configuration of energy storage power stations has become an important measure to ensure the safety and stability of household electricity consumption.

Household energy storage usually includes equipment such as batteries, supercapacitors and hot water storage tanks, which can effectively store clean energy such as solar energy and wind energy produced by the family. The advantage of this is that it allows the family to be self-sufficient when needed, and at the same time, it can also sell excess electricity to the power grid, thereby obtaining certain economic benefits.

Household energy storage can help families be self-sufficient and no longer rely on the power grid, thereby reducing household electricity costs. In addition to self-sufficiency, household energy storage can also sell excess electricity to the power grid, thereby obtaining certain economic benefits. When the power quality is poor, it can also improve the power quality by storing electricity and providing power support.

In the island construction and development projects, these islands are inhabited by a small number of residents and island militiamen, as well as mobile signal transmission base stations, maritime radar stations and other power-consuming equipment. In harsh natural environments, conventional photovoltaic power generation or wind power generation cannot provide stable and reliable electricity for the islands in this scenario.

Install an off-grid smart island microgrid on this island, use the energy management system to accurately coordinate and control the power generation, energy storage, and power consumption conditions, flexibly allocate the connection methods of each user, and realize the coordinated control and economic operation of "source-grid-load-storage". The off-grid smart island microgrid not only solves the energy consumption problem of island residents, provides power supply guarantee for island and marine development and protection, but also provides a technical template for the construction of smart island microgrids.

In areas such as oil exploration and coal mines, there is no reliable, fixed, and economical power supply that can continuously supply power. After the energy storage system is configured, when a fault occurs on the grid side or the power supply needs to be stopped for normal maintenance, the battery system on the load side converts the DC in the battery system into AC through the energy storage converter to supply power to the user side.

During normal operation, the time period when the user side draws power from the grid side and the time period when the battery pack stores energy are reasonably allocated by the system controller according to the peak, flat and valley periods of electricity billing. The offshore oil field power grid is a typical isolated island power grid with small power supply capacity and large load capacity. The instant of large load startup and grid failure will cause large frequency fluctuations. Configuring energy storage can effectively improve the frequency regulation performance of the power system and maintain frequency stability.

High-power emergency energy storage power supply is a subdivision of the new energy battery industry, which can be simply understood as an "oversized power bank". Among them, portable energy storage power supply can be used in outdoor scenes such as RV travel, night fishing, and outdoor camping.

In addition, in the event of a failure in the power supply system of the power grid, the emergency energy storage power system can provide power guarantee for emergency rescue, which can be used in a variety of scenarios such as rescue and hospital backup power supply.

Urban rail transit energy storage system refers to the process of introducing energy storage system to recover and recycle the large amount of regenerative electric energy generated by regenerative braking of urban rail transit vehicles. It is the requirement and development direction for building an energy-saving society in the future.

Flywheel energy storage is the most widely used in urban subways. Flywheel energy storage uses electric motors to drive the flywheel rotor under vacuum magnetic suspension conditions to rotate at high speed to store energy. When the speed increases, it is charged, and when the speed decreases, it can be discharged. High power density and long life are its technical characteristics. It can not only respond to high-power charging and discharging within 5 milliseconds, but also has a charging and discharging life of up to tens of millions of times.
