The global energy structure is changing against a dual-carbon backdrop, and clean energy development is accelerating. Photovoltaic and wind energy are currently the two main sources of new energy in China. Furthermore, China is currently speeding up the development of the so-called energy storage system, which is comparable to a sizable charging treasure.
Energy storage can be used in the power generation side, user side, and other fields as a support for the development of new energy. The industrial and commercial energy storage system market is now progressively active, driven by factors like time-sharing tariff adjustment, widening peak-valley price differential, power limitation, and lower cost of energy storage.
Commercial and industrial energy storage systems are typical user-side energy storage system applications. As a large user of electricity, industrial and commercial energy storage can not only reduce the cost of electricity, but also improve the social image of enterprises, Energy storage systems close to the load power supply, reduce the loss of power transmission, and can be used with new energy such as photovoltaic, improve the rate of photovoltaic self-generation and self-utilization.
The current business and industrial profit model is always evident. One for the peak and valley arbitrage, i.e., when using low electricity price charging in the electricity consumption valley and high electricity price discharging in the electricity consumption peak. To shorten the payback period for industrial and commercial energy storage, China is now gradually improving the time-of-day tariffs. In Guangdong, Zhejiang, and other provinces, some areas can realize a day two charging two put. Second, photovoltaics can be combined with commercial and industrial energy storage.
When the photovoltaic power generation is large, industrial and commercial can not be used by themselves, can be stored in the energy storage system, when the photovoltaic power generation is insufficient, and then will be released in the storage system for the load to use the electricity, photovoltaic power generation configuration of the storage system can enhance the rate of clean energy consumption, but also for the industrial and commercial to save the electricity bill expenditure. In addition to the above two points, industrial and commercial energy storage systems can also be used as a backup power supply, we know that in the summer of these two years, some areas in the south will appear power limitations, and energy storage system can be the main load power supply, to cope with sudden power outages, can be used for industrial and commercial owners to save some of the investment cost of UPS power supply equipment.
There are many energy storage methods, such as pumped storage, flywheel storage, electrochemical energy storage, and so on. In recent years, electrochemical energy storage has developed rapidly. Which is represented by lithium iron phosphate batteries, thanks to the progress of energy storage technology and the gradual reduction of energy storage costs. Taken together, lithium iron phosphate battery has a good performance in energy density, safety, cycle times, etc., so their commercial applications continue to expand.
The whole energy storage system includes not only the battery system but also BMS, EMS, PCS, etc. BMS battery management system is divided into three levels of architecture, the single battery, battery pack, and battery cluster hierarchical management, monitoring the battery SOC, SOH, and timely reporting of anomalies, EMS as an energy management system, the energy storage system for real-time monitoring, panoramic analysis, diagnostic early warning to ensure the safety and reliability of the energy storage system, to ensure the safety and reliability of the system. EMS, as an energy management system, provides real-time monitoring, panoramic analysis, diagnosis, and warning of the energy storage system to ensure the safe and reliable operation of the system. If the industry and commerce want to arbitrage the peaks and valleys, they can set the design of charging and discharging hours of the energy storage system through the EMS system.PCS energy storage converter is a device connected between the energy storage battery system and the power grid or the loads, which can convert the DC power from the battery system into AC power to be output to the grid or AC loads, and also convert the AC power from the power grid into DC power to be charged to the batteries.

The industrial and commercial distributed energy storage system can store and release electrical energy according to energy demand and supply, realizing energy regulation and peak and valley filling. Storing electrical energy during peak hours and then releasing it during peak hours can reduce the peak value of the grid load, improve grid stability, and greatly enhance economic efficiency, realizing the purpose of energy cost reduction.
The energy storage capacity of industrial and commercial distributed energy storage systems can be adjusted according to demand. Enterprises of different sizes can choose the energy storage capacity that suits their energy consumption and production characteristics to meet different power needs.
Distributed energy storage systems usually use energy storage technologies, such as battery storage system capacitors. These technologies have high energy conversion efficiency, which can effectively convert electrical energy into stored energy and release it again, reducing energy waste.
Commercial and industrial distributed energy storage systems are usually combined with renewable energy generation systems, such as solar photovoltaic or wind power generation. By combining renewable energy with energy storage systems, sustainable use of energy can be realized, reducing dependence on traditional energy sources and reducing the negative impact on the environment.
Distributed energy storage systems can provide backup power and short-term power supply capacity to provide emergency power support in the event of a power system failure or outage. This helps to improve the stability of the power system and reduce the impact of power supply interruptions on commercial and industrial users.
To monitor, regulate, and optimize the management of energy flows by monitoring and controlling energy consumption and storage, commercial and industrial distributed energy storage systems are typically combined with an energy management system (EMS). To achieve economic and environmental benefits that benefit everyone, improve energy efficiency through intelligent energy management.
The commercial and industrial distributed energy storage system has the following qualities: high energy efficiency, sustainable development, improved power system stability, and energy management optimization. It also can regulate energy and fill in energy peaks and valleys. For industrial and commercial users, distributed energy storage systems are a crucial option when it comes to sustainable development and energy management.
