摘要
随着风能、太阳能等新能源的快速发展,储能系统在分布式发电系统中扮演着平衡能源供需、提供持续可靠电能和调节功率波动的重要角色,成为分布式发电系统中的关键组成部分,因而通过应用信息化技术以实现分布式储能系统更高的自动化程度、智能化水平和运维效率已成为趋势。介绍分布式储能能量管理系统的需求、硬件拓扑结构、网络拓扑结构以及其信息系统实现方式等,并重点阐述分布式储能信息系统实现方式中的分布式储能信息化总体架构、信息平台接入系统、主要功能及平台界面设计等。其中,信息平台接入系统包括电池管理系统(BMS)、能量管理系统(EMS)、储能逆变器(PCS)以及其他电气设备,前三者与其他电气设备在储能系统中均发挥不同的作用,彼此相互写作,实现对分布式储能系统的监控、优化和控制。分布式储能能量管理系统的主要功能包括数据采集与监测、远程监控与操作、能量管理与优化、数据分析与预测、能源交易以及故障诊断与预警。分布式储能信息化系统具有较高的可靠性和稳定性,能够适应较为复杂的工业环境。但随着信息化技术的广泛应用,也带来网络安全和数据隐私等方面的挑战。为了确保系统的安全性和数据的机密性,在分布式储能系统建设时还应采取恰当的安全措施和隐私保护措施。

Abstract
With the rapid development of new energy sources such as wind and solar energy, energy storage systemsplay an important role in balancing energy supply and demand, providing continuous and reliable power and regula⁃ting power fluctuations in distributed generation systems, and have become an indispensable key component. There⁃fore, through the application of information technology, it has become a trend to achieve a higher degree of automa⁃tion, intelligence and operation and maintenance efficiency of distributed energy storage systems. This paper intro⁃duced the requirements, hardware topology, network topology and information system implementation of distributedenergy storage energy management system. In the implementation mode of distributed energy storage information sys⁃tem, the overall architecture of distributed energy storage informatization, information platform access system, mainfunctions and platform interface design were introduced. Among them, the information platform access system in⁃cludes battery management system ( BMS), energy management system ( EMS), energy storage inverter ( PCS)and other electrical equipment, which play different roles in the energy storage system and write each other toachieve the monitoring, optimization and control of the distributed energy storage system. The main functions of dis⁃tributed energy storage energy management system include data collection and monitoring, remote monitoring and re⁃mote operation, energy management and optimization, data analysis and forecasting, energy trading, and fault diag⁃nosis and early warning. This distributed energy storage information system has high reliability and stability, andit can adapt to more complex industrial environments. However it has also brought challenges in network securityand data privacy with the wide application of information technology. In order to ensure the security of the systemand the confidentiality of data, appropriate security measures and privacy protection measures should also betaken during the construction of the system.
