// The following are the common application scenarios of the Distributed Energy Storage Device:
1. Peak Shaving and Frequency Regulation of the Power System:
Against the backdrop of a decrease in the proportion of traditional thermal power and an increase in the proportion of new energy power generation, new energy power generation such as wind power and photovoltaic power has intermittency and volatility, resulting in unstable grid loads. Distributed energy storage devices can charge during low-power-consumption periods and discharge during peak-power-consumption periods, quickly responding to grid dispatching. They can effectively smooth out power fluctuations and enhance the stability of the power system. For example, in regions rich in new energy sources, by deploying distributed energy storage power stations, the problem of curtailed wind and solar power can be solved. Excess electrical energy can be stored and released when the power demand is high, achieving the temporal and spatial transfer of electrical energy.
2. Peak Shaving and Valley Filling in the Industrial Field:
In the production processes of some industrial enterprises, there is a significant difference between peak and valley power consumption. Electricity prices are high during peak periods, leading to expensive electricity costs. Distributed energy storage devices can charge during low electricity price periods and discharge for internal use by enterprises during peak periods, reducing the electricity costs of enterprises. Large industrial enterprises such as steel plants and chemical plants can use energy storage devices to achieve flexible allocation of electrical energy, reduce their dependence on peak power from the grid, optimize the energy usage structure, and enhance their economic benefits.
3. Energy Conservation and Efficiency Improvement in Commercial Buildings:
Large commercial buildings such as shopping malls and office buildings have high power consumption for devices such as air conditioners and lighting, and their peak power consumption periods coincide with the peak periods of the power grid. Installing a distributed energy storage system can reduce the amount of electricity purchased from the grid during peak periods and lower electricity costs. At the same time, it can provide emergency power for important devices in case of a power outage, ensuring the normal operation of commercial activities.
4. Power Supply Guarantee in Remote Areas:
In remote mountainous areas, islands and other regions, due to the complex geographical environment, it is costly and difficult to erect long-distance transmission lines, and the power supply reliability is low. Distributed energy storage devices combined with small-scale renewable energy power generation devices (such as solar panels and small wind turbines) can build off-grid microgrids, providing a stable power supply for local residents. For example, some islands have solved the needs of residents' daily electricity consumption and seawater desalination by building integrated "wind-solar-storage" microgrids, getting rid of their dependence on the external main power grid.
5. Electric Vehicle Charging and Battery Replacement Facilities:
With the rapid increase in the number of electric vehicles in use, large-scale centralized charging will have a great impact on the power grid. Deploying distributed energy storage devices in electric vehicle charging and battery replacement stations can charge when the grid load is low and discharge during the peak charging periods of electric vehicles, relieving the pressure on the grid and improving the power supply capacity and stability of the charging facilities. In addition, energy storage devices can also provide backup power for charging piles, ensuring that the charging needs of electric vehicles can still be met in case of a grid failure.
6. Emergency Rescue Scenarios:
After natural disasters such as earthquakes and floods occur, grid facilities may be damaged, resulting in power outages in the disaster areas. Distributed energy storage devices are small in size and mobile, and can be quickly transported to the disaster areas to provide power support for important places such as emergency command centers, hospitals, and communication base stations, ensuring the smooth progress of rescue work and maintaining the basic living order in the disaster areas.
// FAQ
Q: Which new energy power generation devices can the distributed energy storage device be adapted to?
A: It can be seamlessly connected with various renewable energy devices such as photovoltaic power generation, wind power generation, and hydropower generation. Through the intelligent management system, it can achieve coordinated optimization of power generation, energy storage, and power consumption, improving energy utilization efficiency.
Q: Can the device supply power immediately after a power outage?
A: It supports millisecond-level response. When the power grid outage is detected, the energy storage device can instantly switch to the backup power supply mode to ensure uninterrupted power supply for key devices and avoid production interruptions or data losses caused by power outages.
Q: How to select suitable energy storage devices for different application scenarios?
A: Factors such as capacity requirements, charging and discharging power, cycle life, and cost budget need to be comprehensively considered. For example, large-capacity devices are required for peak shaving and valley filling in the industrial field, while portability and fast response capabilities are more emphasized in emergency rescue scenarios.
