BSLBATT mainly provides a full set of solutions for energy storage bi-directional converters, DC converters, energy management systems (EMS), battery management systems (BMS), energy storage batteries, etc., which can be scientifically matched according to actual applications to ease the pressure of emission reduction on the power generation side, promote the shift from power transmission to electricity transmission on the transmission and distribution side, improve the quality of power supply and interactive power supply demand on the user side, and energy management system mainly addresses and covers large centralized energy storage power plants and distributed energy storage solutions.
Centralized large scale battery energy storage systems are mainly used in large photovoltaic power generation, large wind farms, hydroelectric power generation, etc., generally with a capacity of MW or more, which are connected to the 10KV (35KV) medium and high voltage power grid, acting as peak regulation, frequency regulation and reactive power support stations. On the power generation side, it can help smooth the output of new energy, solve the phenomenon of wind and light abandonment, promote the storage and consumption of new energy, and on the transmission and distribution side, it can cut the peaks and fill the valleys, improve the utilization rate of electric energy, help the external and internal smooth, and accelerate the construction of a modern energy storage and transportation network with multi-energy complementarity.
Widely used in industrial parks, industrial and commercial parks, office buildings and other scenarios, close to the user side, in the form of decentralized points connected to the 380V (10KV) distribution network, self-generated automatically, the balance of the Internet, but also peak shaving and valley filling, with demand-side management.
Networked microgrid system is mainly used in industrial and commercial parks, schools, communities and other large grid presence, connected to the customer distribution network, through the energy management system to achieve the complementary use of a variety of renewable energy sources, to provide high reliability, high power quality of green energy for the customer side, with independent and grid-connected solutions and operation modes, can achieve grid-connected power control, seamless switching, peak and valley reduction, grid support, reactive power compensation, smoothing new energy output and other functions.
Island microgrid system is a complete system of power generation, transmission, distribution, consumption and energy storage in the region, which adopts the multi-energy complementary approach and uses wind power, photovoltaic power, diesel generator, small hydropower and other renewable energy sources. It is mainly used in remote border guard posts, independent islands, grassland mobility pastoral areas, etc., mainly to solve the problem of power supply in areas without electricity.
Energy storage is a way of converting electrical energy into other forms of energy to be stored and released when needed. Energy storage can be divided into pumped storage, electrochemical storage, flywheel storage, compressed air storage, thermal storage, and gravity storage. Energy storage power plants can exist independently or can be built in conjunction with new energy sources, such as "energy storage + photovoltaic" and "energy storage + wind power", but in the field of new energy, the main application is electrochemical energy storage, which is also discussed in this paper.
Energy storage systems have three application scenarios: power generation side, grid side, and customer side.
On the power generation side, there can be shared energy storage, auxiliary services such as frequency regulation and peaking, suppressing fluctuations in new energy output, tracking new energy output plans, improving new energy outgoing DC, and flexible ramp climbing.
On the grid side, it can improve the possibility of grid power supply, delay grid investment, improve equipment utilization, line expansion, and tide optimization.
On the user side, it can have backup battery, peak shaving, demand reduction, and demand response.
New energy configuration storage, can avoid abandoning wind and light, scenery depends on the natural environment, issued by the power has unstable characteristics, when the grid does not need photovoltaic, wind power output, energy storage can store excess power, when the grid pressure is small, and then output, to avoid waste.
Peaking refers to when the power load and power consumption is not uniform, put in other generating units, synchronous adjustment in grid connection, to maintain the balance of power consumption. Frequency regulation refers to when the power load or power generation output changes significantly, by other generating units before participating in the secondary frequency regulation. Peaking and frequency regulation is to respond to the demand of the grid and solve the problem of instability of the grid itself, which is paid and even subsidized in several provinces, mostly for large energy storage power plants operating independently.
In remote islands, the national grid of high-voltage lines to places, "energy storage + photovoltaic" is a complete power system, solving the problem of powerless border soldiers, and even grow fresh vegetables.
Electrochemical energy storage is battery energy storage, currently there are lead-acid batteries, lithium-ion batteries, all-vanadium liquid flow batteries, zinc-bromine liquid flow batteries, sodium-sulfur batteries, currently mainly lead-acid batteries and lithium-ion batteries. The mainstream of the two types of batteries, and lithium batteries are more widely used. One reason is that the cycle life of lithium batteries is higher than that of lead-acid batteries, in the whole life cycle, lithium batteries can cycle 4000-6000 times, lead-acid batteries can only cycle 500-1000 times. Second, the volume of lithium batteries is much smaller than lead-acid batteries, only one tenth of lead-acid batteries, and more environmentally friendly.
The application scenarios of energy storage systems can be divided into three categories: grid-side, grid-side and customer-side. Grid-side energy storage systems are mainly used to alleviate grid blockage, delay transmission and distribution capacity expansion and upgrade, and make profits for grid frequency regulation; user-side energy storage systems are mainly used for peak-valley spread arbitrage.
