云计算平台技术及其在电网调度中的应用

Cloud Computing Platform Technology and Its Application in Power Grid Dispatch

计算平台技术是对海量数据进行高效可靠的存储、访问以及分析处理的核心技术。详细分析了传统计算平台技术,包括并行计算技术、分布式计算技术、网格计算技术。在此基础上引入了云计算平台的概念。从定义介绍、网络拓扑、软硬件架构等方面对云计算平台进行了详细论述,并比较了云计算同网格计算的不同之处。最后,提出了基于云计算平台的新一代电网调度控制系统的原型概念设计,并从系统整体架构、基础云平台核心技术和业务应用模块3个方面对该系统进行了阐述。该系统充分发挥了云计算的技术优势,将全局性集中式分析业务与区域性分布式实时业务有机整合,实现了电网调度的集约化管理。

Computing platform is the core technology of highly efficient and reliable storage,access,analysis and processing for massive data. This paper presents a detailed analysis of the traditional computing platform technology including the parallel computing,distributed computing and grid computing.On this basis, the paper introduces the concept of cloud computing,giving a detailed description of the cloud computing platform from aspects of concept,network topology,hardware and software architecture and differences between the cloud computing and the grid computing. The prototype of a new power dispatch system based on the cloud computing platform is introduced. The system is discussed from aspects of overall structure design,core technology of the basic cloud computing platform and service application module. Taking full advantages of the cloud computing technology,the system integrates the globe centralized analysis service and regional distributed realtime service to realize the intensive management of the power grid dispatching.
