Analyze the application of lithium iron phosphate battery energy storage system in electric energy

The application of lithium iron phosphate battery energy storage system in electric energy. The application scenarios of lithium iron phosphate batteries can be divided into three aspects: power consumption, power consumption and energy storage. As an emerging application scenario, energy storage lithium batteries are also receiving more and more attention. Energy storage is one of the important means to solve the intermittent fluctuations of new energy wind power and photovoltaic power generation and realize the function of peak, flat and valley. There are currently two mainstream lithium energy storage batteries: ternary lithium and lithium iron phosphate. Application of Lithium Iron Phosphate Battery Energy Storage System in Electric Energy Energy Storage of Lithium Iron Phosphate Battery. JPG◆Control system The lithium iron phosphate battery energy storage system is controlled by a programmable controller (PLC) and a human-machine interface (HMI). One of the key functions of the PLC system is to control the charging time and charging rate of the energy storage system through standardized communication inputs, control signals and power supplies, and to integrate with the rest of the system. You can access the Internet via dial-up or online. It has multiple layers of protection to restrict access to its various functions, and provides self-meaning reports and alarm functions for remote monitoring. Power Conversion System The design purpose of the power conversion system is to charge and discharge lithium iron phosphate batteries to provide better power supply quality, voltage support and frequency control for the local power grid. It has a complex and fast, multi-quadrant, dynamic controller (DSP) and a special control algorithm, which converts the entire range of output devices, that is, the cycle absorbs from full power to full power output. It is suitable for reactive power and any combination of active power and reactive power demand. ◆The lithium iron battery pack reactor is composed of many single cells. The energy storage system of the lithium iron phosphate battery can be stored economically in a fixed manner, and can supply large-scale power according to the need. It is a long-life, low-maintenance, and high-efficiency technology that supports stepless expansion of power supply and energy storage capabilities. Energy storage systems are particularly effective for renewable energy suppliers, grid companies and end users. Lithium-iron battery energy storage systems can be applied to all links of the power supply chain to convert intermittent renewable energy such as wind and solar energy into stable power output. Power supply optimization methods in remote areas The lag of fixed investment in power grids and the application of peak-shaving and power-cutting. The energy storage system can also be used as a backup power source for substations and communication base stations. The lithium iron phosphate battery energy storage system is an environmentally friendly energy storage system with the lowest ecological impact of all energy storage technologies, and does not use elements such as lead and cadmium as important reactants. ◆Power supply in remote areas In sparsely populated remote areas, such as islands, diesel generators are usually used as a single source of energy. Due to load changes, diesel generators often run at non-rated power, resulting in a maximum decrease in fuel efficiency of about 30%. When wind power and photovoltaic power generation account for about 30% of the total diesel power generation, this The coming instability will directly reduce the reliability of the local power grid and restrict more renewable energy power generation. However, through the deployment of lithium battery energy storage systems, this ratio can reach 100%, and the payback period of the project can be shortened to 3 years. As fuel prices rise, economic benefits become more obvious. ◆Traditional battery systems used in communication base stations are usually used as backup power sources, which can ensure about 5-20 short-term or instantaneous power failures per year, and avoid frequent deep charge and discharge cycles. The target market for the 5kw8-hour deep-cycle energy storage system is communication base stations in off-grid or weak-network areas, enabling these communication base stations to achieve repeated cycles or use hybrid systems such as wind energy and solar energy. The lithium iron phosphate battery energy storage system greatly reduces operating costs and diesel consumption, thereby prolonging the service life of diesel engines and reducing the sensitivity of communication base stations to environmental temperature changes. ◆Peak load reduction The lithium battery energy storage system can reduce the peak energy load of users at the power distribution terminal, promote the utilization of power grid equipment, and meet the needs of end users. As a result, the load factor of the grid is added. The following chart shows the significant energy-saving effect.
