先进能量管理系统是一种新型的电网多目标趋优控制的自动化系统,其底层采用＂数据共享平台＂技术实现数据的网络共享。文中介绍了该平台的整体框架和平台中的分布式内存缓存技术,通过该技术将共享数据以＂键值对＂的形式存储在分布式内存中,具有简单性、开放性和高效性。最后,提出了数据序列化技术,包括公共信息模型和状态估计结果的序列化,该技术能有效压缩数据量从而使数据读写更加高效。无论是实验结果还是实际应用效果均验证了所提出的数据共享技术的有效性。

The advanced energy management system （AEMS） is a new-type automatic system for performing multi-objective, near-optimal and closed-loop control of electric power grids. The data-sharing platform （DSP） is the fundamental platform of AEMS that provides data sharing service. The structure of DSP is proposed, and distribution memory cached technique is described. This technique uses string ＂key-value＂ mapping to store shared data in distribution memories, which makes things simple, open and efficient. Finally, serialization techniques for the common information model （CIM） data and results of state estimation are proposed. CIM data is compressed before transfer to network which makes data interchange more efficient. The effectiveness of the techniques of data sharing proposed is proved by test results and application.
