面向智能配网的能量管理系统体系结构

Architecture of Energy Management System Faced Smart Distribution Grid

为满足分布式电源(DG)高渗透率下智能配网的能量管理需求,开发面向智能配网的能量管理系统已显得非常重要。简要介绍了兼具MAS技术和SOA技术两者优点的MAS-SOA技术,分析了MAS-SOA在构建智能配网能量管理系统中的技术优势,提出了智能配网能量管理系统的MAS-SOA体系结构,在该分层体系结构中由代理(Agent)封装而成的智能服务主体通过企业服务总线(ESB)与其他Agent或原子服务主体进行信息交互,智能服务主体间的高度自治性和协作性以及灵活的业务流程管理使得智能配网能量管理系统更适应运行环境的变化。最后详细阐述了MAS-SOA架构的系统设计和关键技术,并以微网群的能量管理为例证明基于MAS-SOA构建智能配网能量管理系统是可行的。

To meet the requirements of energy management of smart distribution grid with high penetration of distribution generations（ DG）, the development of the energy management system for smart distribution grid becomes very important, and multi agent system and service oriented architecture （MAS-SOA） for the establishment of the distributed, open and flexible system will provide new ways and means. We briefly introduced the MAS-SOA technology, analyzed the technical advantages and design ideas of the MAS-SOA in building energy management system for smart distribution grid ,and put forward the MAS-SOA architecture with the advantages of both MAS and SOA technology of energy management system for smart distribution grid. In this layered architecture, the specific task of energy management is realized by agent service, which is interacted with other agent services through the enterprise service bus（ESB）. The main interaction between the services and flexible collaboration business process management allows the energy management system for smart distribution grid to adapt to change in operating environment and to help the operator make a reasonable decision making against the current power and market status. Finally, wide-area microgrid energy management is presented as an example to prove the architecture of energy management system based on MAS-SOA feasibility.
