Multi process real-time network applications in Distribution Management System

The heart of every Power System Control Center (PSCC) - Distribution Management System (DMS) software is sophisticated calculation real-time core of Network Applications. Crucial applications of the control center such as State Estimator - Power Flow, Volt VAr Control, Fault isolation and service restoration, must operate in real-time, providing high performance calculation, communication and data processing. This paper presents implementation of real-time multi-process Distribution State Estimator and Volt VAr control and those important performance considerations specific to the scheduling processes of these applications, by leveraging multi-core processor technology. Real-time Scheduler as one of the crucial performance wise components is analyzed. The scheduling process and algorithm are analyzed in detail with its dependence on the nature of Power Networks. Tests are done and results for multi-process Distribution State Estimator scheduling executions on multi-core processors are presented.
