A container fmilan米兰体育官网 package-type storage battery system
We have developed a package-type milan米兰体育官网 system to efficiently control the charging and discharging of storage batteries. A test for the operation of the system has been commenced at our Yokohama Works. In the event of a power outage, the package-type power storage system functions as an emergency power source to keep electrical equipment operating at the minimum level necessary. Usually, it helps use electricity efficiently in the form of peak shaving and the utilization of nighttime power. If connected to a solar photovoltaic panel, the system also makes it possible to adjust the time of electricity consumption and use surplus power to recharge the battery.
After an operation test at our facility, milan米兰体育官网 will be commercialized from the end of this fiscal year for public organizations, private enterprises, system manufacturers and developers that are considering anti-disaster actions.
Necessity of power storage systems
The Great East Japan Earthquake has renewed our awareness of the necessity for storage batteries for use in keeping important facilities operating milan米兰体育官网 event of a disaster or planned power outage, and in securing power sources for local community centers, schools and other evacuation locations. This type of battery can be charged when surplus power is available and discharged when the availability of power is limited, both during emergencies and under normal operating conditions. This helps power resources to be used wisely in ways such as those described below.
- During peak hours milan米兰体育官网 daytime, discharge as much as possible exceeding the contract demand so that the peak power demand can be controlled;
- Charge the battery and increase milan米兰体育官网 for electrical appliances that need to be powered 24 hours per day at nighttime when power consumption is low; and
- Use surplus power to milan米兰体育官网 when surplus photovoltaic power is available, for example on fine holidays.
Using these functions to eliminate the power differences between daytime and nighttime and efficiently utilize power supply facilities can be expected to enhance the efficiency of equipment investment and contribute to the overall local economy. milan米兰体育官网 also represents an advantage for users, as it helps to reduce basic electricity rates and partly recover their equipment investment with the use of equipment to ensure security and safety.
The mass introduction of photovoltaic power and other natural energy sources has led to concern regarding growing instability within systems. Systems with storage batteries are a viable solution to this problem, so this is a further reason why they are increasingly considered to be necessary.Functions and specifications of milan米兰体育官网
To achieve these functions, we have developed a package-type storage battery system. Integrating a milan米兰体育官网, control device and other major devices into a container, the system has the following functions.
Functions of milan米兰体育官网
| Item | Description |
|---|---|
| Automatic power supply milan米兰体育官网 outage | milan米兰体育官网 and isolated operations are detected and power supply to important equipment begins automatically.(note 1) |
| milan米兰体育官网 | If the 30-minute power demand exceeds a predetermined value, the discharge of electricity corresponding to milan米兰体育官网 excess begins automatically so that peak power demand can be reduced.(note 2) The milan米兰体育官网 and/or the solar photovoltaic panel is/are available as a power source. |
| milan米兰体育官网 surplus electricity and nighttime electricity for charging | Surplus power from solar photovoltaic generation is used to charge the milan米兰体育官网. The battery may also be charged from the power distribution system at nighttime when electricity rates are low. |
| Cooperation with photovoltaic power generation | When the system is connected to the power distribution system, the outputs from solar photovoltaic generation and the milan米兰体育官网 are combined to partly supply the power for consumption by the equipment in the building.(note 3) The power discharged from the milan米兰体育官网 supplements the variations in the fluctuations of photovoltaic power. This ensures that the power supply to the equipment settles at the same value. |
(note 1)
A blackout continues for around ten seconds before the milan米兰体育官网 begins. Install UPS in each device, such as computers, where power outages are not acceptable.
(note 2)
If milan米兰体育官网 excess is greater than the rated value for this product, the contract demand may be exceeded. Be sure to consider the capacity of the equipment before designing the capacity.milan米兰体育官网
(note 3)
In this operational test, no reverse power flow to the system is performed.milan米兰体育官网
