Organisation: Zurich University of Applied Sciences, Switzerland
Short biography of the chair:Dr Segundo, received a PhD degree from Imperial College London, United Kingdom in 2013. From 2007 to 2008, he worked in the Automation and Control group in the Corporate Research Centre of ABB, in Switzerland. From January 2013 to July 2014, Dr Segundo was a postdoctoral research fellow at the school of electrical engineering of the KTH Royal Institute of Technology in Stockholm, Sweden. Since summer 2014, he is research associate in the Electric Power Systems and Smart Grid Lab at ZHAW. Dr. Segundo is Senior Member of the IEEE, chair of the IEEE Task Force ” Application of Big Data Analytic on Transmission System Dynamic Security Assessment” and chair of the international annual workshop DynPOWER. He is responsible for several national and international projects and some of his areas of interest include control, dynamics, stability and quantification of the impact of renewable energies in large transmission networks, as well as data analysis techniques in advanced metering infrastructure such as PMUs and smart meters.
Abstract: Energy transitions worldwide are pushing towards more sustainable societies demanding for more environmentally friendly power generation and urging to reduce the use of nuclear and carbon based energy technology to a minimum. Moreover, future energy systems are evolving to low-inertia networks where utilities are staring to face new challenges associated to the dramatic increase of inverter connected devices. Consequently, utilities require higher degree of observability in the network and thus are becoming more dependent of advanced metering infrastructure, monitoring systems and high frequency synchronized wide-area devices in order to improve the decision making and situational awareness of the transmission system. As solution, utilities have adopted methods to handle, process and analyze the information acquired. Since the characteristics of the power systems are considerably different due to the diverse geographical locations, dimension of the systems and nature of the loads, the current handling processes are not necessarily the same nor the most advanced solution. In the context of the IEEE Task Force Application of Big Data Analytic on Transmission System for DSA, a data handling survey to different utilities around the world was recently completed. This panel presents the most important findings of the survey with key authors of the document with experience on power systems from diverse geographical locations and it will be a platform to debate about how the current practices could be improved.

Title of presentation: Towards inertia forecasting based on data-driven power system models
Abstract: Data-driven models are being proposed as a simple solution to dynamic modelling, particularly for frequency stability. This talk presents new perspectives and some work done towards implementing an inertia forecasting system through PMU data-driven frequency dynamics models.
Panelist 2:
Name: Dr. Walter Sattinger
Organisation: Swissgrid – Principal Grid Studies Engineer, Switzerland
Short biography: Dr Sattinger is currently a Principal Grid Studies Engineer at Swissgrid, where he is working at the interface between planning and operation and is responsible for the implementation of concepts to enhance system security. Dr Sattinger has extensive experience in power system dynamic analysis and has been working for 32 years in the field of power system modelling and power system control. In several studies he has worked in all required project stages from the onsite data collection to the organisation and execution of system tests, dynamic model identification, system modelling, performing of studies, reports and finally the presentation of the study results.
Title of presentation: Use of WAM Tools for the Secure Operation of the Continental European Power System
Abstract: Based on the permanent exchange of PMU measurements, the CE transmission system operators have established a monitoring system for the power system dynamic behaviour. With the help of detailed analysis of several significant events, the work of common working group and similar activities on international level will be presented.
Panelist 3:
Name: Dr. Emil Hillberg
Organisation: Research Institutes of Sweden (RISE), Sweden
Short biography: Dr Emil Hillberg is an expert in analysis of power system dynamic phenomena, with a research background in smart transmission grid solutions and mitigation of blackouts.He has a twenty-year long international career within the power system area, including previous positions at ABB, SINTEF and STRI, in Switzerland, Norway and Sweden.
Title of presentation: Development of SIPS for enhanced security and capacity of the power systems
Abstract: System Integrity Protection Schemes (SIPS) are in use to increase secure power transfer in regions or cases where N-1 operation cannot be maintained. Utilization of PMU data in the development and deployment of solutions, enable SIPS to become response-based and thus providing increased security for a broader range of scenarios.
