Placeholder content for this accordion, which is intended to demonstrate the .accordion-flush class. This is the third item's accordion body. Nothing more exciting happening here in terms of content, but just filling up the space to make it look, at least at first glance, a bit more representative of how this would look in a real-world application.

Main functions and application scenarios of industrial and commercial energy storage

The main role of industrial and commercial energy storage

Industrial and commercial energy storage is a bridge connecting the power generation side and the user side to maintain the stability of the power grid. New energy power generation is intermittent and volatile. As the proportion of new energy power generation increases, the volatility on the power generation side is easy to affects the power generation.

Network stability will have an impact; in addition, with the popularization of new energy vehicles and the gradual deepening of industrial digitalization, the user-side load will continue to increase. Energy storage is the bridge that connects the power generation side and the user side to maintain the stability of the power grid.

Main application scenarios:

Individually configured energy storage:

There are two main considerations for industrial and commercial users to separately configure energy storage: First, it can save electricity costs for enterprises by peak shaving and valley filling. Second, use energy storage as a backup power source in case of emergency.

Optical storage (charge) integration:

Judging from the actual implementation of integrated optical storage (charging) projects in the past, integration generally appears with charging stations. The integration of photovoltaic power generation, energy storage, and charging integrates photovoltaic power generation, energy storage, charging, and other functions. It converts solar energy into electrical energy through the solar roof system and stores the electrical energy for the daily charging of electric vehicles. The application of energy storage makes it possible for user-side self-use, improves the self-use rate of distributed photovoltaics, and can also alleviate the impact of high-current charging at charging piles on the regional power grid.

Microgrid:

Microgrids are localized small-scale power generation and distribution systems with their own power generation capabilities. They are mostly industrial park microgrids, island microgrids, and microgrids in remote areas. Microgrids can operate independently of the main grid or in conjunction with the main grid. For microgrids that operate independently of the main grid, energy storage can smooth new energy generation and use it as backup power. For grid-connected microgrids, energy storage can achieve energy optimization, energy conservation, and emission reduction.

Demand for energy storage in factories, charging stations, commercial buildings, data centers, and other scenarios:

Cost reduction in high energy consumption scenarios:

Electricity is a large cost item for industry and commerce. Data center electricity costs account for 60%-70% of operating costs. As the peak-to-valley difference in electricity prices increases, these companies will be able to significantly reduce electricity costs by shifting peaks and filling valleys.

Optical and storage integration increases the proportion of green electricity usage:

The EU's imposition of carbon tariffs will cause major domestic industries to face large cost increases when entering the European market. Every link in the industrial chain production system will have demand for green electricity, and the cost of purchasing green electricity is not small, so a large number of external The factory is building their own "distributed photovoltaic + distributed energy storage".

Transformer expansion:

It should be applied in charging piles, especially super fast charging piles and factory scenarios. In 2012, the charging power of new energy vehicle charging piles was 60 kilowatts. Now it has basically increased to 120 kilowatts and is developing towards super fast charging piles of 360 kilowatts. Under this charging power, ordinary supermarkets or charging stations do not have extra transformers available at the grid level. Because it involves the expansion of the transformer capacity of the grid, energy storage needs to be used to replace it.
