Containerized energy storage calculation model

What is a containerized energy storage system?

The containerized energy storage system is mainly divided into the containerized electrical room and the containerized battery room. The containerized battery room includes battery pack 1, battery pack 2, fire protection system, and battery management system (BMS).

Are SoC estimation results for containerized energy storage systems better than CNN-LSTM?

Therefore, the SOC estimation results for containerized energy storage systems using the CNN–LSTM model are not consistently better than those using the CNN model. Thereason is that certain estimation stages (e.g., areas I and V of Fig. 7 (a)) have a small demand for time-series data.

What is a containerized lithium ion battery energy storage system?

As a novel model of energy storage device, the containerized lithium–ion battery energy storage system is widely used because of its high energy density, rapid response, long life, lightness, and strong environmental adaptability [2, 3].

What is a containerized battery room?

The containerized battery room includes battery pack 1, battery pack 2, fire protection system, and battery management system (BMS). The electrical room includes a data acquisition system and power conversion system (PCS). The energy storage battery cluster is connected to the power transformer through the PCS.

What is the operation strategy of energy storage system?

The operation strategy of this energy storage system is as follows. It acts as a peak shaving and valley filling power source in the grid. The lower limit of the energy storage system discharge SOC is set to 2 %. The energy storage system will stop charging for a moment when the SOC reaches to 90 %.

What is the lower limit of the energy storage system discharge SoC?

The lower limit of the energy storage system discharge SOC is set to 2 %. The energy storage system will stop charging for a moment when the SOC reaches to 90 %. After the temperature of the battery decrease, the energy storage system will continue to charge to 100 %.
