摘要
为应对分布式储能终端给电网的管理和运维带来的巨大挑战,提出了一种基于通用即插即用协议的电池储能系统(battery energy storage system,BESS)终端信息交互机制。首先基于电力物联网标准的建模方法,定义BESS属性、服务和事件3个维度的模型模式规范,构建了一种适用于配电侧BESS的物联终端模型,消除了传统系统中云主站与终端模型间的异构问题。其次,提出一种基于通用即插即用协议的BESS终端与云主站间的注册/识别机制:以BESS终端自描述配置为基础,通过获取云主站的证书或认证来完成身份验证,保证数据的安全,从而实现快速识别与连接。最后以模型和协议映射为核心构建云边端式BESS信息交互机制,并以某配电网馈线中的储能系统为例,通过一致性测试验证BESS终端与云主站各项业务功能信息交互的可行性和有效性。
To cope with the enormous challenges brought by distributed energy storage terminals to the management and operation of the power grid,a battery energy storage system(abbr.BESS)terminal information exchange mechanism based on a universal plug-and-play protocol was proposed.Firstly,based on the modeling method of electric power Internet of Things(abbr.IoT)standard,a model pattern specifications with three dimensions of BESS attributes,services,and events were defined to construct an IoT terminal model applicable to BESS on the distribution side,which eliminates the heterogeneity problem between cloud master and terminal model in the traditional system.Secondly,a registration/identification mechanism between the BESS terminal and cloud master station based on a common plug-and-play protocol was proposed:based on the self-describing configuration of the BESS terminal,identity verification was completed by obtaining certificate or authentication of the cloud master station to ensure data security,so as to achieve fast identification and connection.Finally,a cloud edgebased BESS information exchange mechanism was constructed taking the model and protocol mapping as the core.And taking the energy storage system in a certain distribution network feeder as an example,the feasibility and effectiveness of the information interaction between the BESS terminal and the cloud master station’s various business function information are verified by consistency testing.
