Encourage enterprises to build energy storage equipment

Why should energy storage technology be used in a large-scale application?

The premise of large-scale application of energy storage technology is to set industry standards for energy storage. On the one hand, there have been many safety accidents in energy storage systems around the world. The development of energy storage standards can effectively reduce the danger of energy storage.

Where is energy storage used?

It is mainly used in power transmission and distribution systems with loads close to the equipment capacity. The energy storage is installed downstream of the power transmission and distribution equipment that originally needs to be upgraded to delay or avoid capacity expansion.

What is the implementation plan for the development of new energy storage?

In January 2022, the National Development and Reform Commission and the National Energy Administration jointly issued the Implementation Plan for the Development of New Energy Storage during the 14th Five-Year Plan Period, emphasizing the fundamental role of new energy storage technologies in a new power system.

Why do we need independent energy storage stations?

Independent energy storage stations can meet the needs for energy storage by generators and for peak shaving and frequency regulation by power grids, expanding their channels for revenue generation and improving their economic potential. They will be an important direction for the development of energy storage stations in the future.

How energy storage equipment can be used as a backup power supply?

The energy storage equipment in the substation can be used as a backup power supply to directly supply power to the DC load . The secondary frequency regulation is mainly controlled by automatic power generation. The response time when the thermal power unit provides secondary frequency modulation generally takes 1– 2 min.

How can energy storage improve time-of-use electricity price management?

On the user side, energy storage can manage the user's time-of-use electricity price, manage capacity costs, and improve power quality. These three application scenarios are integrated with each other. When users build energy storage for time-of-use electricity price management, they also reduce load and capacity cost management.
