Abstract :
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.
