Problems solved by technology

However, the usual large-scale industrial electricity consumption and non-residential electricity consumption are mostly in the peak period of electricity consumption, and the high electricity price during peak hours will bring higher operating costs
The price of electricity is relatively cheap during off-peak hours, but the usage is relatively small

Embodiment Construction

[0033] Such as figure 1 Shown is an industrial energy storage system for time-of-use electricity pricing. The energy storage system includes a battery pack 1 , a battery management system 2 , a bidirectional converter 3 , an energy manager 4 , an electric meter 5 , and a high-voltage box 6 .

[0034] The battery pack 1 is discharged under the control of the energy manager during peak periods or peak periods, and charged under the control of the energy manager during valley periods or normal periods.

[0035] The battery management system 2 includes a battery monitoring system and a battery management system. The battery monitoring system is responsible for monitoring battery information and reporting the data to the battery management system. When an abnormality occurs, disconnect the high-voltage power contactor to make the battery pack out of operation and ensure the safe use of the battery.

[0036] The bidirectional converter 3 can convert direct current into alternating ...

Abstract

The invention provides an industrial energy storage system for time-of-use electricity price, which is mainly composed of a battery pack, a battery management system, a bi-directional converter, an energy manager, an electric meter and a high-voltage box. In areas where time-of-use tariffs exist, the industrial energy storage system realizes the commands of charging the valley or flat-section battery packs and discharging the cusp or peak-section battery packs under the premise of meeting the energy balance among the commercial power, energy storage and load through the dispatching function ofthe energy manager, thereby achieving the purpose of reducing the power consumption cost. The invention also provides a charging and discharging strategy of the energy storage system.

Description

technical field [0001] The invention relates to an industrial energy storage system for time-of-use electricity pricing, and also provides a charging and discharging strategy for the energy storage system. Background technique [0002] The peak-valley time-of-use electricity price is a kind of electricity price system that calculates the electricity cost according to the peak electricity consumption and the low-valley electricity consumption respectively. In mainland China, large-scale industrial electricity consumption and non-residential electricity consumption mostly adopt a time-of-use electricity price charging strategy. Peak power consumption generally refers to the electricity consumption during the period when the power consumption is relatively concentrated and the power supply is tense. For example, during the day, the charging standard is higher; During the night, the charges are lower. [0003] The purpose of implementing peak-valley electricity prices in China...
