本文主要研究电网分析系统(PGAS)中QoS提供的解决方案，它是对电力信息系统的改进。该解决方案由两部分组成。第一部分是基于元服务和CCM的PGAS网格QoS提供模型。该模型是根据数据密集型QoS保证网格系统的需求提出的。第二部分是自适应调度算法，它处理 PGAS 中的两种类型的任务（有/没有 QoS 保证任务）。基于GridSim对两类任务的仿真结果表明，我们的解决方案能够满足PGAS中用户的各种QoS需求，并且调度算法取得了良好的效果。
This paper mainly focuses on solution to QoS provision in power grid analysis system (PGAS) which is an improvement for the electric power information system. The solution consists of two parts. The first part is the grid QoS provision model for PGAS based on metaservices and CCM. The model is proposed based on requirement of data-intensive QoS guaranteed grid systems. The second part is an adaptive scheduling algorithm which handles two types of tasks (with/without QoS guarantee tasks) in PGAS. Simulations of two types of tasks based on GridSim show the results of our solution can meet various QoS requirements of users in PGAS and the scheduling algorithm take good effect.
