Problems solved by technology

However, the disadvantage of such an architecture is that the real-time control of the energy storage control system is poor, which is mainly manifested in three aspects:
[0005] (1) The real-time performance of the EMS to obtain the system load adjustment request is poor;
[0006] (2) The real-time performance of the communication between EMS and PCS / BMS is poor;
[0007] (3) The real-time performance of the behavior of EMS controlling PCS / BMS is poor

Abstract

The present invention relates to a control system for an energy storage system. The system comprises a first bus configured to transmit a control instruction of the energy storage system; and a secondbus configured to transmit state data of the energy storage system. Through the system, the communication efficiency among the components in the energy storage system can be greatly improved, so thatthe total efficiency of the energy storage system is improved. The efficiency of clean energy is improved.

Description

technical field [0001] The present invention generally relates to the field of energy storage devices, and in particular, relates to a control system for an energy storage system. Furthermore, the present invention also relates to an energy storage system with the aforementioned control system. Background technique [0002] In recent years, clean energy such as wind energy, solar energy and other fields have shown a trend of rapid development. The large-scale development of clean energy and its own volatility have brought challenges to grid balance. Energy storage systems based on electrochemical technologies are playing an increasingly important role in power system balance. [0003] The energy storage system needs to have the functions of energy storage and release, and these functions need to be realized by corresponding control systems. The control system of the energy storage system needs to collect external inputs, including but not limited to power grid frequency m...
