大规模电力系统往往需要跨多个具有自治性的子网,是典型的网格系统.根据电力系统的实际需要,将网格计算技术应用于电力系统之中,为电力系统提供先进的方法和平台.提出了基于网格的大规模电力系统体系结构,对各层进行了详尽的讨论,设计和分析了电力网格中间件(PGM),并给出了基于电力网格中间件技术进行在线安全评估的应用示范.实验结果显示,基于提出的体系结构进行DSA应用耗时较短.
Many autonomic subnets were required by large scale electric power system, which was one typical grid computing system. According to practical demands of power system, grid computing was applied in power system for supplying one advanced method and platform. Firstly architecture of large scale electric power based on grid computing was proposed, and every layer was introduced in detail. Secondly, key part-power grid middleware was designed and analyzed. Lastly, based on PGM, the application of online security assessing was given. Experiment result shows that proposed architecture spends less time in dynamic security assessing than tradition methods which are not using grid computing.
