Container energy storage intelligent dispatching system and method

Abstract

The invention discloses a container energy storage intelligent dispatching system and method. The container energy storage intelligent dispatching system includes a plurality of energy storage terminals, and each energy storage terminal accesses a load power grid through a contactor. Each energy storage terminal includes: an energy management system which is connected to the contactor and controlson-off of the contactor; a power conversion system which is in communication connection with the energy management system and is connected to an energy storage unit; and the energy storage unit whichincludes a storage battery, wherein the energy management systems of all the energy storage terminals are in communication connection with each other. The container energy storage intelligent dispatching system is flexible and convenient, can timely, accurately and stably invoke other energy storage terminals to supply power to a load while one or a plurality of energy storage terminals are abnormal or maintained regularly, and the load is unbalanced, can reduce loss, and can increase economic benefits.

Description

Technical field [0001] This application relates to the technical field of smart grids, in particular to a container energy storage intelligent dispatch system and method. Background technique [0002] At present, the container energy storage systems are generally integrated into the power grid individually, through the two-way converter to achieve AC and DC power conversion and power flow control, and through the user-side power distribution room step-up transformer (400V / 10kV) into the 10kV power grid. However, there is more than one container energy storage system for the containers between each plant. They are independent of each other and cannot be dispatched to each other. This leads to a problem: if one or several of the container energy storage systems fails or fails to supply loads in time for other reasons such as scheduled maintenance and unbalanced loads. In this way, the overall coordination and flexibility of the entire plant's container energy storage system cannot...

AI Technical Summary

Problems solved by technology

[0003] The system of the present invention is based on the fact that the existing container energy storage system cannot supply the load in time due to problems or other reasons such as regular maintenance and unbalanced load, and provides a system that can schedule other container energy storage terminals to supply power to the load in a timely, accurate and stable manner. Reduce losses and improve economic benefits
