Containerized Energy Storage System

As electrochemical energy storage continues to be promoted and applied within the power system. Containerized energy storage system applications become more mature. Energy storage systems can be factory-produced and more and more mobile energy storage is being shipped around the world. The main features of the system are centralized data management, centralized system control, centralized system output to the outside, high reliability, modular design, intelligent integrated container design, and with strong practical experience support, perfect temperature control system, automatic fire extinguishing system, video monitoring system, escape door design, access control alarm system, compact structure, reasonable layout and other advantages. It can be applied to peak shaving and valley filling, smoothing out wind/photovoltaic fluctuations, etc.

The container is equipped with special fire-fighting and air-conditioning systems to ensure the safety of the system, where the fire-fighting system senses the fire through smoke sensors, temperature sensors and other safety equipment, and automatically extinguishes the fire; the special air-conditioning system controls the air-conditioning cooling and heating system through thermal management strategies according to the external ambient temperature to ensure that the temperature inside the container is in the right range and prolong the service life of the battery.

The modular design of container energy storage system adopts international standardized container size, which allows ocean and road transportation, can be lifted and installed by overhead crane, and is highly mobile and not restricted by geography. In addition, the containerized energy storage system can be factory produced and assembled and commissioned directly in the workshop, which greatly saves the construction and operation and maintenance costs of the project and realizes accident isolation.

Usage scenarios
⚫ Peak shaving and valley filling
Through the charging and discharging process of energy storage battery to adjust the user's electricity consumption curve, to achieve the low price of electricity in the valley period to the peak period of the high price of electricity use. From the user's value point of view, it can realize arbitrage through peak and valley price difference, reduce the basic capacity fee, and reduce the user's distribution transformer configuration capacity and load loss.

⚫ Smooth out wind/photovoltaic fluctuations
To improve the controllability of wind power rate, this energy storage system can exchange power with wind power system precisely and efficiently; meanwhile, the energy storage elements can suppress different types of fluctuating power according to their respective energy storage characteristics, and the suppressed wind power output power can meet the requirements of real-time dispatching of power system.
