A comparison of dms workflows scheduling concepts

Abstract

© Kaunas University of Technology. The development of computational and communication technology enabled the introduction of a Distribution Management System (DMS) as a sophisticated approach to solve various problems regarding the power supply in modern society. These advanced systems execute a large number of workflows to meet the requirements and provide the desirable functionalities. Very high demands for computational resources, during the DMS operation, imposed a necessity for an adequate DMS workflow management. Three DMS workflow scheduling concepts (architectures) are presented in this paper: centralized, mixed and hierarchical. These scheduling concepts are compared by different parameters, such as performance, scalability and complexity of implementation. The conducted experimental study shows that the hierarchical scheduling concept not only provides the best performance, but is also the most scalable and entirely eligible in terms of implementation complexity.
