06-Household + Energy Storage
More and more households are installing photovoltaic (PV) power plants as a supplement to energy use or a source of income from electricity bills, and the configuration of energy storage power plants has become an important measure to ensure the safety and stability of household electricity use.
Household energy storage usually includes equipment such as batteries, supercapacitors and hot water storage tanks, which can effectively store home-generated solar energy, wind energy and other clean energy. The advantage of this is that it allows households to be self-sufficient when they need to be, and at the same time, they can also sell excess power to the grid, thus obtaining a certain amount of economic returns.
Household energy storage can help households become self-sufficient and less dependent on the grid, thereby reducing the cost of electricity for the household. In addition to self-sufficiency, household energy storage can also sell excess electricity to the grid, thereby gaining some financial benefit. It can also improve the quality of power when it is poor by storing power and providing power support.
07-Microgrid + Energy Storage
In recent years, China has vigorously developed the construction of sea islands, which live with a few residents, island guarding militia, and also have mobile signal transmitting base stations, maritime radar stations, and other power-using equipment, and the conventional photovoltaic power generation or wind power generation is unable to provide stable and reliable power for the sea islands in such scenarios under the harsh natural environment.
Installation of off-grid smart island microgrids on such islands utilizes energy management systems to precisely coordinate the control of power generation, energy storage, and power consumption conditions, flexibly deploy the connection mode of each user, and realize the coordinated control and economic operation of “source-network-load-storage”. Off-grid intelligent island microgrid not only solves the problem of island residents’ energy consumption, provides power supply guarantee for island and ocean development and protection, but also provides a technical model for the construction of intelligent island microgrid.
08-Mining + energy storage
Such as oil exploration, coal mining and other areas, there is no reliable fixed, continuous power supply of economic power. After configuring the energy storage system, when the grid side fails or normal maintenance needs to stop power supply, the load side is powered by the battery system through the energy storage converter to convert the DC in the battery system to AC for the user side.
During normal operation, the time period during which the user side draws power from the grid side and the time period during which the battery pack stores energy are reasonably allocated by the system controller according to the peak, flat and valley time periods of power billing. Offshore oilfield power grid is a typical isolated island power grid, small power capacity, large load capacity, large load start-up moment and grid failure will cause large frequency fluctuations. Configuration of energy storage can effectively improve the frequency regulation performance of the power system to maintain frequency stability.
09-emergency energy storage power supply
High-power emergency energy storage power supply is a segment of the new energy battery industry, which can be simply understood as “oversized charging treasure”, of which portable energy storage power supply can be applied to caravan travel, night fishing, outdoor camping and other outdoor scenes. In addition, in the event of grid power system failure, emergency energy storage power system can provide power protection for emergency rescue, can be used for emergency rescue, hospital backup power and other scenarios.
10-Urban rail transit + energy storage
Urban rail transit energy storage system refers to, urban rail transit vehicle regenerative braking generates a large amount of regenerative power, the introduction of energy storage system to recover regenerative power and recycling process, is the future construction of energy-saving social requirements and development direction.
Flywheel energy storage is the most widely used in urban subways. Flywheel energy storage is the use of electric motors to drive the vacuum magnetic levitation conditions of the flywheel rotor rotating at high speed to store energy, when the speed is increased, charging, when the speed is lowered, it can be discharged. High power density, long life is its technical characteristics, not only can respond to high-power charging and discharging in 5 milliseconds, and charging and discharging life is as high as tens of millions of times.
