Job Description

Fixed-term, full-time for 18 months

Job summary

Applications are invited for a Research Associate (RA) position within the Control and Power Research Group for an investigation of data-driven methods for assessment of power system stability with a high penetration of inverter-based resources. The post holder will cover two broad areas. First is assessment of methods for obtaining key system parameters such as inertia and damping pertaining to frequency stability as both system-wide and locational quantities when these area mixture of physical and synthetic contributions. Second is an exploration of general methods of Dissipating Energy Flow tracing that can be applied to oscillatory modes arsing from both synchronous machines and inverters. The studies will be undertaken as both theoretical analysis and case-study testing in a Simulink platform.

Duties and responsibilities

The purpose of this research is to study is to contribute to our groups overall drive toward stability assurance of grids with inverter-based resources (IBR). The intention is address cases where the control model of the IBR is not known or is uncertain so that a form of system identification from live system data is required or where model-free identification of oscillatory modes is needed. System identification could be applied with various levels of assumed system structure and we are interested to establish how general or specific the structure assumptions should be for reliable identification of response to system contingencies such as faults and outages. A further focus is to trace the location of equipment participating in oscillatory modes. The Dissipating Energy Flow (DEF) method has been shown to be successful in doing this in traditional networks of synchronous machines but there are conflicting reports on whether the method can be successfully extended to over networks with IBRs. We wish to explore the theoretical limits of the application of DEF and to verify this with case studies.

The findings from this work will be disseminated at workshops and conference and written up for academic publishing.

Requirements

The successful candidate should have research experience demonstrated through a PhD, or suitable alternative experience, in the field of stability analysis of power systems. A thorough understanding and experience of modelling both traditional synchronous machines and inverter-based resources is required.
