Winter/Spring Publications

The ADOreD doctoral candidates have busy writing and publishing papers in the beginning of 2026

In January Bernardo Castro Valerio published his paper: "Transmission expansion planning for hybrid AC/DC grids using a mixed-integer non-linear programming approach" presenting a Non-Linear Mixed-Integer Optimization approach for operationally aware transmission expansion planning in hybrid AC/DC grids.

And just a few weeks later Luis Angel Garcia Reyes published the paper: "Data-Driven State-Space Modeling for Small-Signal Stability Analysis of Black-Box Power Converters", introducing a data-driven methodology to build accurate state-space models of black-box voltage source converters (VSCs) directly from voltage and current measurements at the point of connection — enabling eigenvalue-based small-signal stability analysis without knowing the internal converter dynamics.

In February Mario Alejandro Useche Arteaga published his paper: "𝘖𝘱𝘵𝘪𝘮𝘪𝘻𝘪𝘯𝘨 𝘵𝘩𝘦 𝘰𝘱𝘦𝘳𝘢𝘵𝘪𝘰𝘯 𝘰𝘧 𝘦𝘯𝘦𝘳𝘨𝘺 𝘪𝘴𝘭𝘢𝘯𝘥𝘴 𝘸𝘪𝘵𝘩 𝘱𝘳𝘦𝘥𝘪𝘤𝘵𝘪𝘷𝘦 𝘯𝘰𝘯𝘭𝘪𝘯𝘦𝘢𝘳 𝘱𝘳𝘰𝘨𝘳𝘢𝘮𝘮𝘪𝘯𝘨 – 𝘢 𝘤𝘢𝘴𝘦 𝘴𝘵𝘶𝘥𝘺 𝘣𝘢𝘴𝘦𝘥 𝘰𝘯 𝘵𝘩𝘦 𝘗𝘳𝘪𝘯𝘤𝘦𝘴𝘴 𝘌𝘭𝘪𝘴𝘢𝘣𝘦𝘵𝘩 𝘌𝘯𝘦𝘳𝘨𝘺 𝘐𝘴𝘭𝘢𝘯𝘥" saying:

And in March, publications went crazy with 3 different DC's publishing papers about their work:

• Kriti Agrawal published: "Multi-stage convex polynomial regression for small-signal stability in power systems"

• Nicolae Darii published: "Enhancing simulation fidelity of offshore wind turbines through DLL-based black-box models"

• Germano Rugendo Mugambi published: "Impedance-based sensitivity analysis of wind turbine generator".

Nicolae Darii's was selected amongst the 𝗯𝗲𝘀𝘁 𝗪𝗶𝗻𝗱 𝗮𝗻𝗱 𝗦𝗼𝗹𝗮𝗿 𝗣𝗮𝗽𝗲𝗿𝘀 𝗼𝗳 𝟮𝟬𝟮𝟱 for the IET Special Issue.
