Problems solved by technology

The communication and interaction process of the energy storage system connected to the grid is complex
The communication protocols currently used are traditional transmission-oriented protocols, which only guarantee the accuracy and security of data transmission. The data lacks clear meaning and does not have self-describing ability. Both communication and functional configuration of these intelligent electronic devices require On-site personnel operate, and the transformation of the existing distribution network automation system requires a lot of manpower and material resources, and the maintenance cost in the later period is also very high. How to simplify the process of connecting a large number of intelligent electronic devices to the active distribution network and realize the equipment The self-description of energy storage system is another difficulty in grid-connected coordinated control technology

Abstract

The invention relates to the field of smart distribution network, and provides a plug-and-play information interaction method for a battery energy storage system. The method comprises analyzing the typical application scenarios of grid connection of the battery energy storage system and the running state of each typical application scenario; establishing a self-describing model based on the IEC61850 standard, and performing self-describing expression and configuration; and enabling the battery energy storage system and a power distribution main station to establish a discovery registration mechanism to complete grid connection and performing a consistency test of the information exchange between the power distribution main station and the battery energy storage system. The method standardizes the information interaction of the battery energy storage system connected to the grid, so that the battery energy storage system is upgraded from restricted connection and fixed connection to orderly and standardized connection.

Description

technical field [0001] The invention relates to the field of intelligent distribution networks, in particular to a plug-and-play information interaction method for a battery energy storage system. Background technique [0002] The ever-increasing demand for electricity and the large-scale development of renewable energy make the operation of the grid face enormous challenges, mainly including low energy utilization efficiency, serious pollution, difficulty in connecting renewable energy to the grid, increasing peak-to-valley difference in power demand between day and night, and grid stability and security. In recent years, energy storage technology has developed rapidly in the power system, and has been used in various applications such as peak shaving and valley filling, emergency power supply, power quality, and renewable energy grid integration, and has been used in active and reactive power transmission and distribution systems. Great progress has also been made in the a...
