In the field of energy storage, energy storage power stations play an important role. The application of energy storage power station technology runs through all aspects of power generation, transmission, distribution, and power consumption in the power system. It realizes peak shaving and valley filling of the power system, smoothing and tracking plan processing of renewable energy power generation fluctuations, efficient system frequency modulation, and increases power supply reliability. 1. What is an energy storage power station Energy storage power stations are power stations set up to regulate peak and valley power consumption problems. Energy storage power stations are composed of energy storage units and auxiliary facilities, access devices, and measurement and control devices. The establishment of energy storage power stations is to store the electricity that we are going to waste during low-peak power consumption periods and release it back to the power grid during peak power consumption to achieve the purpose of peak shaving and valley filling. 2. Composition of energy storage power station system Energy storage power station system can be divided into six main parts, namely renewable energy, energy transmission system, conversion system, storage system, management system and network access system.

The key technologies of smart microgrids mainly include the following: (I) Renewable energy generation technology At present, smart microgrids are mainly based on a variety of renewable energy sources, and the power input is mainly photovoltaic, wind power, hydrogen energy, natural gas, biogas and other mature power generation technologies. (I) Key technologies of energy storage Energy storage is an indispensable part of microgrids. It can play a role in peak shaving and valley filling in microgrids, greatly improving the utilization efficiency of intermittent energy. With the continuous development of science and technology, the current energy storage mainly includes battery energy storage, flywheel energy storage, superconducting magnetic energy storage, and supercapacitor energy storage. The more mature energy storage technology is lead-acid battery, but it has the problems of short life and serious lead pollution. In the future, the marketization of high energy storage, low cost, and high-quality performance graphene batteries will bring spring to the energy storage industry. The current development cost of energy storage technology is relatively high. Countries around the world are working on this technology, but they all have a common goal, which is to achieve the goal of "low cost + high energy storage". (II) Smart microgrid energy optimization dispatching technology Different from the traditional power grid dispatching system, the smart microgrid dispatching system belongs to the horizontal multi-energy complementary optimization dispatching technology, which can fully explore and utilize the direct complementary substitutability of different energy sources, and can not only realize the output of heat, electricity and cold, but also realize the energy exchange of light/electricity, heat/cold, wind/electricity, direct/alternating current.

This method is not only beautiful, but also reduces the energy consumption and carbon emissions of buildings, achieving green buildings and sustainable development.           2. Agricultural field: The integration of photovoltaic and agricultural fields can realize the "agricultural light complementary" mode. Installing photovoltaic panels above the farmland and carrying out agricultural production below not only makes full use of land resources, but also improves the efficiency of agricultural production. At the same time, photovoltaic panels can also provide power support for agricultural irrigation, breeding, etc., and promote the modernization of agriculture.           3. Transportation field: The application of photovoltaics in the transportation field is mainly reflected in the solar power supply system of transportation facilities such as highways, railways, bridges, etc. By installing photovoltaic panels on traffic facilities, it is possible to provide power support for traffic lights, surveillance cameras, etc., while reducing dependence on traditional electricity and improving energy efficiency.           4.

       In the process of accelerating the realization of dual carbon goals and building a new power system, energy storage technology is gradually becoming one of the key technologies to support the stable operation of the new power system and optimize resource allocation. Among them, PCS (Power Conversion System) energy storage converter is the core equipment of the energy storage system, and its performance and application directly affect the overall efficiency and stability of the energy storage system.        PCS energy storage converter, full name Power Conversion System, is a key equipment in the energy storage system, used to realize energy conversion and bidirectional flow between energy storage batteries and power grids. It can convert DC power into AC power or AC power into DC power to meet the charging and discharging requirements of the power grid for the energy storage system. PCS energy storage converter plays the role of "bridge" in the energy storage system, connecting the energy storage battery and the power grid to ensure the efficient and stable operation of the energy storage system.         The working principle of PCS energy storage converter is mainly based on power electronics technology, and realizes the conversion and bidirectional flow of electric energy by controlling the on and off of switching devices. When the grid needs the energy storage system to discharge, the PCS energy storage inverter converts the DC power in the energy storage battery into AC power and outputs it to the grid; when the grid needs the energy storage system to charge, the PCS energy storage inverter converts the AC power in the grid into DC power and stores it in the energy storage battery. During the charging and discharging process, the PCS energy storage inverter also needs to perform precise power control and energy management according to the needs of the grid and the status of the energy storage battery to ensure the stable operation and efficient utilization of the energy storage system.

As the world pays more and more attention to renewable energy, wind, solar and energy storage systems have attracted widespread attention as a solution to convert wind and solar energy into electricity and effectively store it. Among them, energy storage batteries are the core components of wind, solar and energy storage systems, and their performance and application are directly related to the efficiency and reliability of the entire system. In wind, solar and energy storage systems, the core role of energy storage batteries is the storage and release of energy. Due to the intermittent and unstable nature of wind and solar energy, the electricity they generate often fluctuates, making it difficult to directly meet the stable power supply needs of the power grid. At this time, energy storage batteries can play an important role. When wind and solar resources are abundant and the power generation exceeds the power grid demand, energy storage batteries can store excess electricity; when wind and solar resources are insufficient or the power grid demand is peak, energy storage batteries can quickly release electricity to ensure the stable operation of the power grid. In addition, energy storage batteries can also optimize the operating efficiency of wind, solar and energy storage systems. Through intelligent control strategies, energy storage batteries can smooth the fluctuations of wind and solar resources, reduce the phenomenon of wind and solar abandonment, and improve the utilization rate of wind and solar resources. At the same time, energy storage batteries can also participate in the peak and frequency regulation of the power grid to improve the stability and economy of the power grid. In summary, energy storage batteries play a vital role in wind, solar and energy storage systems. With the continuous advancement of technology and the expansion of application areas, energy storage batteries will play a more important role in the future, providing strong support for the utilization of renewable energy and the optimization of energy structure.

Industrial and commercial energy storage development has achieved significant breakthroughs in recent years. As the national peak-to-trough price gap further widens and the cost of lithium iron phosphate batteries declines, the internal rate of return (IRR) of industrial and commercial energy storage has steadily increased, and its economics has become increasingly prominent. Against this background, industrial and commercial energy storage has gradually become the fastest-growing segment in the energy storage market.   The energy storage system, on the surface, consists of batteries, PCS converters, BMS, EMS and other electrical circuits, protection, monitoring systems, fire protection, etc. However, there are big differences between source grid-side energy storage and industrial and commercial energy storage.   First, industrial and commercial energy storage pays more attention to integration. Compared with large energy storage containers, industrial and commercial energy storage is more likely to adopt the form of integrated energy storage cabinets. This integrated design makes the energy storage system more compact and occupies a smaller area, adapting to the needs of industrial and commercial scenarios.   Secondly, industrial and commercial energy storage capacity is relatively small. Because its main purpose is to meet the company's users' own photovoltaic needs and reduce electricity costs, rather than participating in grid dispatching. Therefore, compared with source-grid side energy storage, industrial and commercial energy storage has lower requirements for system control.   In addition, the profit model of industrial and commercial energy storage is also different from that of source-grid side energy storage. Industrial and commercial energy storage mainly achieves profitability through peak-valley electricity price difference arbitrage, demand response, and ancillary services. In source-grid side energy storage, profit paths include dispatching auxiliary services, power market transactions, etc.   As a new energy storage development model, industrial and commercial energy storage is quite different from source-grid side energy storage in terms of system focus, business logic, and profit model. As industrial and commercial energy storage technology continues to mature and market demand continues to expand, industrial and commercial energy storage will play an increasingly important role in my country's energy storage industry in the future.     Driven by policies and markets, my country's industrial and commercial energy storage market is ushering in a golden development period. Jntech Renewable Energy will increase investment and continue to innovate to meet the diverse and personalized needs of industrial and commercial energy storage and help the rapid development of my country's new energy industry.
