Variable Reactance Criteria to Mitigate Voltage Deviations in Power Transformers in Light- and Over-Load Conditions

Autor: Marta Haro-Larrode

Publikováno v: Machines, Vol 11, Iss 8, p 797 (2023)

In this paper, variable reactance (VR) criteria are proposed to mitigate voltage deviations in power transformers under light-load inductive and capacitive conditions, as well as for over-load conditions. Under capacitive load conditions, power trans

A coordinated control hybrid MPPT algorithm for a grid-tied PV system considering a VDCIQ control structure

Autor: Marta Haro-Larrode, Ángel A. Bayod-Rújula

In this paper, a new coordinated maximum power point tracking (MPPT) algorithm has been developed for a grid-tied PV system, whose inverter follows a VDCIQ control scheme. The control objectives of this system are shared between 2 converters: a DC bo
