Blind Efficient Method for Optimizing Jiles-Atherton Model Parameters
Conde Garrido, Juan Manuel; Ugarte Valdivielso, Jone; Aizpurua Unanue, Jose Ignacio; Barrenetxea, Manex; Silveyra, Josefina María (IEEE, 2026)We introduce a novel blind optimization method for determining the parameters of the Jiles-Atherton model of hysteresis, eliminating the need for user-provided initial guesses or search spaces. A carefully designed ... -
Power Transformer Modelling for the Evaluation of a Reinforcement Learning-Based Inrush Current Minimization Strategy
Ugarte Valdivielso, Jone; Barrenetxea, Manex; Torres, Asier; Stewart, Brian G.; Aizpurua Unanue, Jose Ignacio (IEEE, 2025)Inrush currents in power transformers can affect the transformer lifetime and the reliability of electrical grids. Various inrush current minimization techniques have been proposed to mitigate these effects. To validate ... -
Reinforcement learning-based controlled switching approach for inrush current minimization in power transformers
Ugarte Valdivielso, Jone; Aizpurua Unanue, Jose Ignacio; Barrenetxea Iñarra, Manex; Brian G., Stewart (Elsevier, 2026)Transformers are essential components for the reliable operation of the power grid and the connection of renewable energy sources (RES) to them. The transformer core is constituted by a ferromagnetic material and depending ... -
Transformer Model for Inrush Current Minimization
Ugarte Valdivielso, Jone; Aizpurua Unanue, Jose Ignacio; Barrenetxea, Manex; Brian G., Stewart (Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2026) -
Uncertainty Distribution Assessment of Jiles-Atherton Parameter Estimation for Inrush Current Studies
Ugarte Valdivielso, Jone; Aizpurua Unanue, Jose Ignacio; Barrenetxea, Manex (IEEE, 2024)Transformers are one of the key assets in AC distribution grids and renewable power integration. During transformer energization inrush currents appear, which lead to transformer degradation and can cause grid instability ...
