Embodiment 1

[0046] Such as Figure 1-2 As shown, the application proposes an energy storage shelter, including:

[0047] The battery system includes a plurality of battery modules, each battery module is connected with a shunt switch, and is connected with an energy storage converter through the shunt switch.

[0048] The EMS energy management system is connected to the battery module and the energy storage converter, and the EMS energy management system is connected to a power acquisition module, which is used to collect the work of the battery system and the energy storage converter through remote control, remote measurement and remote communication technology Data, calculate the life time of the battery system in real time, and adjust the output power of the energy storage shelter according to the life time.

[0049]The interface group includes parallel interface, load output interface and communication interface. Both the load output interface and the communication interface adopt qu...

Embodiment 2

[0075] The difference between this embodiment and Embodiment 1 is that the energy storage shelter operates in a parallel operation mode, wherein: in the parallel operation mode, the energy storage shelter is divided into a master and a slave by a specified method, and the online In parallel, the slave machine accepts scheduling and connects to the host machine, and the host machine adjusts the output power of the slave machine through real-time battery life. After the slave machine is connected to the host machine, it operates in P / Q control mode. Other technical features and working principles of this embodiment are the same as those of Embodiment 1.

Abstract

The invention provides a modular energy storage shelter and its operation control method. The energy storage shelter includes: a battery system, including a plurality of battery modules, each battery module is connected with a shunt switch, and all battery modules are connected through the shunt switch The energy storage converter is connected; the EMS energy management system is connected with the battery module and the energy storage converter, and the EMS energy management system is connected with a power acquisition module, which is used to adjust the output power of the energy storage shelter according to the endurance time; the interface group, including parallel interface, load output interface and communication interface. The parallel interface is connected to the power acquisition module and the energy storage converter. The two ends of the load output interface are respectively connected to the power acquisition module and the load distribution box. The communication interface is connected to the EMS energy management system. The invention can carry out online paralleling to ensure uninterrupted power supply to the load, solve the capacity problem of the modular energy storage shelter through the redundant configuration of the master and slave machines, and realize the function of power guaranteeing unlimited battery life.

Description

technical field [0001] The invention belongs to the technical field of mobile energy storage, and in particular relates to a modular energy storage shelter and an operation control method thereof. Background technique [0002] In places where emergency power access is frequently required, such as celebrations, foundation-laying activities, press conferences, etc., clean energy is urgently needed for power supply. [0003] In the existing technology, traditional diesel generators are noisy, polluting, and economical. Modular mobile energy storage shelters are characterized by their modularity, fast response, high conversion efficiency, flexible and controllable functions, and fast mobility. It has gradually become an effective means to solve the above problems. It occupies a small area, does not need fixed infrastructure land and long-distance lines, and can be flexibly mobilized. It is quiet and environmentally friendly, and has high power quality. It can effectively deal wi...
