UAE Cigre-IEEE PES Joint Event
The GCC-Cigre study committee “System Planning, Performance and Energy Efficiency” and the IEEE PES Chapter in UAE are very pleased to invite you to the first UAE GCC-Cigre-IEEE PES joint event in 2018 to be held on December 24th, 2018, in Abu Dhabi, UAE, at TRANSCO premises. This event is in line with the GCC-Cigre and IEEE PES efforts to promote the research and industrial collaboration on System stability and flexibility with effective utilization of renewable energy sources in GCC Countries.
This event is also a part of the joint industrial research collaboration project between Khalifa University, TRANSCO and Manitoba Hydro International (Canada) entitled “Stability Assessment, Visualization and Enhancement (SAVE) Tool for UAE Power System with Renewable Energy Integration” led by Prof. Mohamed El Moursi, Khalifa University. In this event, novel approaches for power system transient stability assessment and power system flexibility will be presented by TRANSCO and Khalifa University researchers.
During the event, distinguished experts and representatives from Department of Energy, Power Companies, Khalifa University of Science and Technology, and potential manufactures will exchange views on the potential ways to support and enhance the power system stability and flexibility with high integration of renewable energy systems

Power System Transient Stability: Background, Current State, and Future Perspective
Power systems represents one of the most advanced and most active fields in nonlinear systems’ stability analysis. Due to the critical nature of power systems combined with high degrees of uncertainty, Power system operators always seek methods to evaluate and maintain system’s stability. This presentation aims to provide an insight into the underlying mathematical and physical principles that governs the dynamical interactions in power systems with an aim to bridge the gap between theoretical studies and industrial practices. This talk will introduce power system transient stability problem in its most generic form and will highlight its challenges and constraints before introducing recent tools and techniques either used by the industry or under development to assess power system stability. A comprehensive analysis of online assessment tools will cover their computational and practical challenges from power system operator's perspective as well as their methodological advantages and drawbacks

Damping Low Frequency Oscillations with Inverter based Renewables
The presence of poorly damped low-frequency oscillations limit the amount of power transfer through the transmission lines of a power system. The occurrence of such oscillations, which are also called inter-area modes, enforces a group of generators in one area to swing against another group of generators in a different area at a frequency of 0.1-1 Hz. Their amplitude can grow over time if sufficient positive damping is not provided .This presentation elaborates on the use of a mixed sensitivity robust control design to improve the overall damping performance of low frequency oscillations for power systems with doubly fed induction generator (DFIG)-based wind power generation. The supplementary damping controller is designed in the Linear Matrix Inequality (LMI) framework which allows the placement of the closed loop poles inside a pre-defined region for improved stability. The damping signal is implemented at the reactive power modulation of the rotor side converter of the DFIG wind turbine (DFIG-WT). The damping contribution of the power oscillator damper (POD) is compared with that provided by the power system stabilizer (PSS) of the synchronous generator. State-space system analysis and time domain simulations show the capability of DFIG-WT to enhance the overall damping of the oscillatory modes even if PSSs are not installed at synchronous generators. In addition, the designed controller shows a robust performance to wind speed variations. The performance evaluation is based on the revised New-England 39 bus system.
