Equivalent Representation of Modern Power Systems with Power Electronics for Stability Analysis

Project description

Stabilising modern power systems

Modern power systems are increasingly reliant on power electronic converters due to the integration of renewable energy sources, energy storage, electric transportation, and high-voltage transmission systems. Unlike conventional synchronous generators, these converters are fully controllable but possess low inertia and limited overload capability. Consequently, analysing and ensuring the stability of power systems dominated by converters becomes complex. Supported by the Marie Skłodowska-Curie Actions (MSCA) programme, the EQUATOR project will develop advanced grid equivalent representations. These representations enable more efficient stability analysis amidst various disturbances, benefiting transmission system operators, manufacturers, and research institutes. The project aims to facilitate the transition to a future European Super Grid, characterised by extensive renewable energy integration.

Objective

Modern power systems have been increasingly penetrated with power electronic converters. This can be explained with the massive integration of renewable energy generation, energy storage utilities, transport electrification, industrial electric drives as well as the wide application of high voltage direct current (HVDC) and flexible alternate current transmission systems (FACTS). Power electronic converters have totally different characteristics compared to conventional synchronous generators as they are fully controllable devices with low inertial and very limited overload capability. These characteristics also increase the complexity to stability analysis of power systems dominated by converters. An accurate grid equivalent representation stands for a powerful tool to improve the efficiency for stability analysis of such system.

In such context, the EQUATOR project aims to develop an effective grid equivalent representation for stability analysis of power systems dominated by power electronics under both small-signal and large-signal disturbances. The obtained equivalent representations will provide powerful tools for TSOs, OEMs and research institutes involved in the planning, design, operation and analysis of modern power systems. Furthermore, the project results will favour the evolution towards the future European Super Grid which involves a high penetration ratio of renewable energy generation and covers a large geographical span.

The researcher’s previous work focused on computational analysis and steady-state grid equivalent representation for power-electronics-dominated systems, which demonstrates his appropriate profile to successfully implement the presented project under the guidance of the supervisor, who is an expert in stability analysis of power electronics systems.
