Home energy storage systems
The smart home energy storage system adopts an integrated home appliance design, exquisite and beautiful, easy to install, and can provide first-class power for residences, public facilities, small factories, etc. Home energy storage system, the use of rooftop solar power generation devices, household wind turbines to generate energy, as well as the social power supply system of low-cost power ** rich power storage into the energy storage system, during the day, household photovoltaic energy storage system absorbs solar power and automatically stores for night load use, in the event of unexpected power outages, the system can also be automatically switched for home backup power supply in time, always ensure the normal operation of lighting, electrical appliances and other equipment systems. In addition to being used as an emergency power supply, the home energy storage system can also balance the electricity load, thereby saving household electricity costs. The smart home photovoltaic energy storage system is similar to a micro energy storage power station, and the operation is not affected by the pressure of urban power supply.
When a meter or current sensor is installed at the grid-connected point, the output power of the inverter remains unchanged when it detects that there is a current flowing to the grid, and the bidirectional converter is activated, and the excess electric energy is stored in the battery, and then released when the photovoltaic power decreases or the load power increases.
The power parameters are sampled, and the inverter or energy management system (EMS) communicates with them to prevent backflow, adjust power generation, and charge and discharge the battery according to the real-time power and cumulative power.
It adopts standard DIN 35mm guide rail installation, which has the advantages of small size, convenient installation and easy networking.
The transformer has a ma-level output for higher accuracy.
The installation of open transformer makes it easier to connect in the field.
The 100ms response time enables faster countercurrent detection and more time for the inverter to adjust the power.
It can be applied to new energy power generation systems such as photovoltaic grid-connected systems, micro-inverter systems, energy storage systems, and AC coupling systems.
Commercial and industrial energy storage systems
C&I energy storage refers to energy storage systems that are used in industrial or commercial terminals. According to different application scenarios, electrochemical energy storage can be divided into power supply side, grid side and user side. The user side can be subdivided into two scenarios: industrial, commercial and residential. The industrial and commercial energy storage system is modular in design and flexible in voltage capacity. C&I energy storage systems mainly include batteries and battery management systems (BMS), converters (PCS), energy management systems (EMS) and other electrification components.
Industrial and commercial energy storage systems can be divided into many types, such as battery energy storage systems, supercapacitor energy storage systems, hydrogen energy storage systems, etc. These systems are able to convert excess electrical energy into reserve energy and release it when needed to meet the needs of industrial and commercial use.
When the power system is faced with sudden power demand or ** interruption, the industrial and commercial energy storage system can balance supply and demand by releasing reserve energy to avoid the impact of power outages and power fluctuations on industrial and commercial activities.
The concept and function of energy storage meters
Energy storage meter refers to the meter used to measure the power input, output and power quality parameters of the energy storage system. The main function of the energy storage meter is to realize the measurement, monitoring, management and control of electric energy exchange in the grid-connected application of energy storage system and power system.
Energy storage meters have a variety of functions. First of all, it can measure the charging and discharging power of the energy storage power station, as well as feedback power quality parameters such as total harmonic distortion, etc., to help managers understand the operation status of the energy storage power station. Secondly, the energy storage meter can also be controlled in terms of synchronization speed, frequency, voltage and other aspects when the energy storage system and the power system are connected to the grid to ensure the stable operation of the system. In addition, the energy storage meter can also realize the measurement and settlement of electricity, power and other indicators.
The concept and function of grid-side metering
Grid-side metering refers to the measurement method of measuring the amount of electricity in the power system, mainly including voltage, current, power, power angle and other parameters. The function of grid-side metering is to record the electricity and quality of the power system, which is used for functions such as electricity sales billing, grid operation parameter analysis, and electricity billing.
In the grid-connected application of energy storage system, grid-side metering data is a must. Through grid-side metering, the power measurement and settlement are realized when the energy storage system and the power system are connected to the grid, so as to ensure the economic benefits and compliant operation of the energy storage system.
Energy storage meter and grid-side metering are important links in the grid-connected application of energy storage system and power system, and the two cooperate with each other to complete the functions of metering, monitoring, management and control, and ensure the economic benefits and operational stability of the system. In the grid-connected application of energy storage system, energy storage meter is the key to realize electricity measurement and settlement, while grid-side metering is a necessary means to ensure electricity settlement and standardized operation of energy storage power station.
