A Battery Enegry Storage Solution is an interconnected collection of loads and distributed energy sources, including wind, solar, diesel generators, or energy storage, that can also be used for electricity generation. It is a Battery Enegry Storage Solution that can realize autonomous control, management, and protection; the purpose is to make up for the places that the national grid cannot cover.
According to the electricity demand in different regions, Battery Enegry Storage Solution can be divided into off-grid and grid-connected; off-grid micro-grids can operate independently without any connection to the grid; they mainly rely on renewable energy to generate electricity, such as solar power, wind power, hydroelectric power, etc.; the voltage frequency converter will adjust the voltage frequency to store within the suitable battery voltage range; it mainly provides power for users in places where natural disasters often occur, and is generally set up in remote areas or An isolated island in the sea to meet the electricity demand of residents.
The grid-connected Battery Enegry Storage Solution can interact with the local grid for energy. When renewable energy power generation is insufficient, the regional grid can be used to obtain electric energy; the grid-connected Battery Enegry Storage Solution has relatively affluent energy acquisition channels, such as photovoltaic power, wind power, hydroelectric power, generator sets, etc. When the power grid fails to obtain energy, the EMS system will automatically switch to an independent operation mode; it is generally set up in residential communities, commercial buildings, hospitals, industrial parks, etc., to improve stable power supply.
Because the microgrid is a vast energy storage system, different components are required to form a stable operation; the following are the components and functions of the microgrid system.
Such as solar photovoltaic panels, wind power generators, steam turbines, geothermal generators, hydroelectric generators, etc.; converting renewable energy into electrical energy can continuously provide energy for the microgrid.
Generally, multiple battery packs are connected in series and parallel to form a battery cluster, and each battery pack itself will also have a BMS protection board to monitor, control and manage the operating status of the battery; to ensure the safety of the battery during operation.
The power conversion system is composed of inverters, battery packs, chargers, controllers, and other accessories; it can accept the input of a variety of renewable energy power generation and will automatically adjust the frequency according to the set voltage and current range values, to ensure that both the input and output are within the control value range.
The energy management system comprises battery packs, power converters, power managers, and monitors; the system will collect real-time data from all components in the microgrid, and the collected data will be aggregated and analyzed. The demand of the load is used to conduct reasonable energy scheduling to ensure the stable operation of the entire microgrid system.
The temperature control system is composed of a temperature sensor, a refrigerator, and a controller; the sensor collects the temperature data of the battery, and the data is fed back to the controller, and the controller will adjust the indoor temperature according to the set temperature threshold to prevent The battery is damaged due to overheating or overcold temperature.
The microgrid uses an advanced aerosol fire extinguishing device; its working principle is to release particles, form tiny suspended particles in the air, generate a large amount of inert gas, diffuse rapidly in the combustion zone, and reduce the oxygen concentration in the area, thus To achieve the effect of fire extinguishing.
