Abstract [en]

Wide Area Monitoring and Control (WAMC) applications provide, among other things, stability control to power systems by using global measurements. However, these measurements suffer unavoidable Quality of Service (QoS) problems, such as delay, during the transmission through a wide area communication network. Such delays potentially lead to failure of the control application. To overcome these effects, mechanisms that provide robustness to QoS problems for control applications and configuration of communication networks to optimize QoS performance have been proposed by several researchers. To optimize utilization of the communication infrastructure and to adapt to variations in QoS, applications can benefit from an interface to request and obtain QoS information from a managed communication infrastructure. To meet this need, a novel Stateful Data Delivery Service (SDDS) for WAMC applications is proposed in this paper. The SDDS monitors the QoS performance online and provides feedback to one or more WAMC applications. To increase reliability of the applications, the SDDS also provides adaptive data link configuration services. By using online QoS measurements and multiple data sources, the SDDS platform can provide a WAMC application with data fulfilling its requirements. To prove the concept, a case study has been performed and the results of this study show that the application using the SDDS can keep a benchmark power system stable even when original data link QoS performance does not meet the application's requirements. The paper also contains a presentation of the SDDS prototype platform under development as a part of the ongoing research.
