Ⅰ：Energy storage terms

Stored energy：The process of storing energy through a medium or device and releasing it when needed. Through flexible charge and discharge control, it realizes the matching of production capacity and energy consumption in time and space. From the perspective of power system, energy storage can be divided into power generation side/power supply side, power grid side, and user side energy storage, of which power supply side and power grid side energy storage is also known as pre-table energy storage or large storage

Pre-sheet energy storage：Energy storage that is directly connected to the power grid and has independent power and electricity meters; Otherwise, it is post-table energy storage, and user-side energy storage is also called post-table energy storage. User-side energy storage is divided into industrial and commercial energy storage and home energy storage. Domestic user-side energy storage mainly refers to the energy storage system applied in the majority of industrial and commercial customers, energy storage equipment can be simply understood as a large charging treasure. Charge when the electricity price is low, discharge when the electricity price is high for enterprise production, and earn the difference between peak and valley electricity prices, thereby reducing the cost of electricity for enterprises.

Peak regulation：Transfer excess electricity from low-power areas to low-power areas. Because electricity cannot be stored on a large scale, it is generally necessary to use as much electricity as is generated. When the power generation of a region is constant, and the power here is not used up, it is necessary to transfer the excess power to the power shortage area through dispatch, or is the common pumped storage

Frequency modulation：For example, the rated frequency stipulated in China is 50Hz, but the electrical appliances in production and life are complex and diverse, and the start-up of the machine will affect the power grid frequency, which requires frequency modulation to improve the power quality.

PCS(Power Conversion System)：Realize the power conversion between the grid and the battery, and monitor and manage the exchange process. It can control the charging and discharging process of the battery, carry out AC/DC transformation, and directly supply AC load in the case of no power grid. PCS is composed of DC/AC bidirectional converter, control unit, etc

BMS(Battery Management System)：It is mainly used for battery pack monitoring, calculation, communication and protection. It mainly consists of battery management chip, analog front end, embedded microprocessor, and embedded software

EMS(Energy Management System)：It can realize real-time monitoring and intelligent management of all equipment in the system. Realize data collection, storage, processing, upload, operation control, operation strategy formulation, and so on, and carry out overall information-based monitoring and management
