Description

Intelligent storage battery system

Technical Field

The invention relates to the technical field of storage batteries, in particular to an intelligent storage battery system.

Background

At present, the peak-to-valley electricity price is also called "time-of-use electricity price". An electricity price system for calculating the electricity fee according to the peak electricity consumption and the valley electricity consumption. Some places in China are also in trial. The peak power consumption generally refers to the power consumption when the power consumption unit is centralized and the power supply is in short supply, such as the daytime, the charging standard is higher, and the valley power consumption generally refers to the power consumption when the power consumption unit is less and the power supply is more sufficient, such as the night, the charging standard is lower. The peak-valley electricity price is beneficial to promoting the electricity consumption unit to stagger the electricity consumption time, and fully utilizing equipment and energy. Peak-to-valley electricity prices are practiced in many countries, with some of the price differences between peaks and valleys reaching over 50%.

According to the document spirit of the joint issue of the economic trade committee of the price bureau of the goods and the electric power industry bureau, the peak-to-valley electricity consumption of the living of residents is a new electricity price category for developing the test points among the residents in the city at present. The method divides 24 hours a day into two time periods, 8: 00-22: the time of 14 hours in total is called a peak section, and the power price of the execution peak is 0.568 yuan/kwh; 22: 00-next day 8: 00 hours are called valley period, and the electricity price of the valley is 0.288 yuan/kwh.

The time interval division of industry and commerce and the regions of the electricity price are slightly different, and the peak is in the region of Guangdong province: 9-12, 9-22 hours, electricity price: 1.3988 yuan; leveling: 8 ~ 9, 12 ~ 19, 22 ~ 24 hours, the price of electricity: 0.8595 membered; and (3) low valley: 0-8 hours, electricity price: 0.4447 yuan.

Compared with the large industry, the price difference between the peak and the valley of general industrial and commercial works is relatively large, and provinces and cities exceeding 0.7 yuan/kilowatt hour are also more, wherein the price difference between the peak and the valley of each voltage grade in Beijing urban areas and suburbs is more than 1 yuan/kilowatt hour, and Jiangsu, Guangdong local cities and Zhejiang are also commonly over 0.8 yuan/kilowatt hour, which undoubtedly provides more favorable conditions for the development of energy storage at the user side of the areas. Furthermore, it is worth noting that the peak-to-valley price difference of Jiangsu, whether it be general industry or large industry, is substantially in excess of 0.7 yuan/kilowatt-hour, which perhaps explains to some extent why Jiangsu user-side energy storage can be leading nationwide.

Because many families, processing enterprises, merchants, underground places and public places have less power consumption at night, and the power consumption is more mainly in the daytime. This results in less electricity being used when the price of electricity is low and more electricity being used when the price of electricity is high, which not only increases unnecessary expenditure, but also increases the burden on the power supply enterprises.

Disclosure of Invention

The invention aims to provide an intelligent storage battery system which can supply power to equipment and charge a storage battery at the same time in the valley time, and can also close the commercial power to independently supply power to the equipment in the peak time so that the equipment can use the valley power all day, thereby solving the problems in the background art.

In order to achieve the purpose, the invention provides the following technical scheme:

an intelligent storage battery system comprises a peak-valley ammeter, a storage battery and an equipment input end, wherein a first time switch and a charging transformer are arranged between the peak-valley ammeter and the storage battery, an inverter and a second time switch are arranged between the storage battery and the equipment input end, the peak-valley ammeter, the first time switch, the charging transformer, the storage battery, the inverter, the second time switch and the equipment input end are sequentially and electrically connected, and the first time switch is electrically connected with the equipment input end; open the first time switch during power consumption low ebb time period, close the second time switch simultaneously, utilize the low ebb electricity to charge for the battery simultaneously and supply power for equipment input, close the first time switch during power consumption peak time period, open the second time switch simultaneously and supply power for equipment input.

As a further scheme of the invention: the first time switch and the second time switch are both switches which can set time and are automatically turned on.

As a further scheme of the invention: the charging transformer can convert alternating current into direct current and charge the storage battery.

As a further scheme of the invention: the storage battery adopts a battery assembly capable of being repeatedly charged and discharged.

As a still further scheme of the invention: the inverter adopts an inverter capable of converting direct current into alternating current.

Compared with the prior art, the invention has the beneficial effects that: the invention can not only supply power to the equipment in the valley time, but also charge the storage battery, and can also close the commercial power in the peak time to supply power to the equipment independently, so that the valley power can be used by the equipment all day, residents and industrial workers are encouraged to consume a large amount of valley power by using the preferential condition of the valley power price, for the power department, the peak power consumption is transferred to the valley time section, thereby not only relieving the gap of the peak power supply and demand, but also promoting the optimal allocation of the power resource, and being a win-win strategy of 'peak clipping and valley filling'.
