Andrés Tomás Martín is developing a doctoral thesis on distributed control of electrical microgrids. The work for the doctoral thesis has resulted in the creation of a tool in MATLAB for the modelling, analysis and simulation of electrical systems, and is resulting in the preparation of several articles, the most relevant of which are detailed below:

• Tomás-Martín, A. García-Cerrada, L. Sigrist, S. Yagüe, y J. Suárez-Porras, «State relevance and modal analysis in electrical microgrids with high penetration of electronic generation», Int. J. Electr. Power Energy Syst., vol. 147, p. 108876, 2023.

This paper proposes an algorithm to systematically calculate the relevance of each state (RC) of a linear system in the input-output response of the system. It explores its application to a linearised model of a microgrid to decide which dynamics are relevant to be included for analysis and/or simulation. The usefulness of the proposed CR was validated by comparing detailed non-linear simulations of a microgrid with non-linear simulations of reduced models as reported by the CR. The results show that the proposed CR provides sensible and clear recommendations even in systems without a clear temporal separation between system dynamics.

• Coordination of Grid-Forming Converters for the Re-synchronisation to the Main Grid Using Multi-Agent Secondary Control, in preparation. In collaboration with the Electrical Systems unit of IMDEA Energía.

This paper proposes an algorithm to synchronise a microgrid with four network-forming converters to the main grid using agent-based secondary control and considering communication delays. It also clarifies the limitations of coordinating network-forming units with a variable consensus objective and proposes an algorithm that achieves synchronisation faster using PD primary control. The proposed method is being validated with experimental results.
