With the ever-increasing raise in electricity demand across the globe and the continued dependence on electricity supply for all socio-economic activities in society, power systems all over the world continue to be interconnected into largescale networks. The integration of conventional power system with renewable energy sources, power electronic based control devices and focus on making the power system more sophisticated and smarter has resulted in development of Wide Area Measurement, Protection and Control (WAMPAC) systems. Power system operators have already adopted synchrophasor data from phasor measurement units for real time monitoring and control of power systems. The well-established standard (IEEE C37.118), the utilization of phasor measurements to improve power system reliability and frequent advancement in technology (communication techniques, protection relay operation, etc.) is paving the way to use synchrophasor data for not only monitoring and visualizing but also to have a reliable and economical operation of power system. It is expected that the continued research and development of phasor data applications will enable the miracle of “Smart Grids” at the transmission level. This talk discusses the preliminary development, and deployment of an experimental wide-area monitoring, protection and control platform with the name of SmarTS-Lab to research and develop applications exploiting synchrophasor data from Phasor Measurement Units (PMUs) to attain smart grid of future. At its current stage, the platform allows both on-line monitoring and off-line analysis. In the future, it will be the cornerstone to a wider platform enabling research on phasor data applications that intrinsically account for ICT aspects.
Rujiroj Leelaruji is a Post-doctoral Research Fellow within the Electric Power Systems (EPS) research group at KTH. The main theme of his research is to develop methods for voltage stability assessment using PMUs data, including perform signal processing methods to extract unwanted dynamics and measurement errors from PMU data and improve visualization approach for wide-area voltage stability monitoring to be used in wide-area early warning systems. Rujiroj received the B.Sc. degree in Electrical Engineering from Sirindhorn International Institute of Technology (SIIT), Thailand, in 2004. He received his MS in 2007 and PhD in 2012, both in Electric Power Engineering from Royal Institute of technology (KTH), Stockholm, Sweden. His Ph.D. thesis was related to the implementation of algorithm for coordinating system protection and HVDC/FACTS controllers to determine preventive measures that will mitigate wide-area system collapse.
