Problems solved by technology

At present, these energy storage devices are generally used when the power grid is out of power, and they are idle at ordinary times. Due to the relatively high reliability of power grid power supply, most of the batteries may not have been used once from the beginning of assembly to the final scrapping. , resulting in a huge waste of resources

Embodiment 1

[0028] Such asfigure 1 As shown, it is a frame diagram of the cooperative control system for the comprehensive utilization of communication base station energy storage according to the present invention, including a cooperative control master station and several base station energy storage cooperative control devices. The master station sends a base station group removal command to each base station through a private network The energy storage coordinating control device, the energy storage coordinating control device of each base station performs the battery load shedding action, and completes the power control target. Among them, the energy storage coordination device of the base station adopts the on-off load shedding scheme of the energy storage AC side of the communication base station.

[0029] Such as figure 2 Shown is a schematic diagram of the topology of the communication base station energy storage AC side on-off load shedding scheme. The overall power supply of t...

Embodiment 2

[0045] The framework of the coordinated control system for comprehensive utilization of energy storage in communication base stations is the same as that in Embodiment 1, such as figure 1 . The difference is that the energy storage coordination device of the base station adopts the energy storage virtual signal load shedding scheme of the communication base station.

[0046] Such as image 3 Shown is the topology of the communication base station energy storage virtual signal load shedding scheme. The overall power supply of the base station is to introduce three-phase mains power from the grid side. After entering, the AC branch enters the UPS control unit. This branch can also be called the AC-to-DC branch, which supplies power to the DC sub-equipment, and the rest supplies power to the AC equipment. In order to realize the regulation of the grid load that the battery can participate in at any time, the following intelligent transformation is required.

Abstract

The invention discloses a cooperative control device, system and method for comprehensively utilizing stored energy of a communication base station, the system comprises a cooperative control master station and a plurality of base station energy storage cooperative control devices, the master station sends a base station group removal instruction to a part of the base station energy storage cooperative control devices through a wireless private network, each base station energy storage cooperative control device executes a storage battery load shedding action to complete a power regulation and control target. The scheme belongs to a transformation scheme, the transformation cost is controllable, the corresponding cooperative control strategy is simple and effective, the control result can be directly fed back to the master station, and a flexible and convenient power regulation channel is provided for cooperative control. Compared with a complex multi-terminal control program added to a cooperative master station side, the scheme can form a base station energy storage cooperative control system through simple transformation, direct and effective regulation and control are provided for a power grid, a set of complex base station energy storage cooperative control equipment does not need to be redesigned to adapt to the cooperative control program, the transformation effect is remarkable, and huge economic benefits are achieved.

Description

technical field [0001] The present invention relates to an energy cooperative control system and method, in particular to a cooperative control device, system and method for comprehensive utilization of energy storage in communication base stations. Background technique [0002] my country's power grid is the power grid with the highest voltage level, the largest transmission capacity, and the longest line length in the world. The stability of the power grid is extremely demanding. It is necessary for the dispatching system to adjust the power generation output of various power sources in real time to maintain the frequency within the stability limit. The power energy storage system can play an important role in peak shaving and valley filling in the process of dispatching system adjustment. Among them, the status of energy storage power stations / distributed energy storage power stations is particularly important. Therefore, my country has ushered in the construction of energ...
