Partial inertial support for PV MPPT systems connected to grid using the IPLL control strategy
(Institute of Electrical and Electronics Engineers (IEEE), 2024)
Conference report
Restricted access - publisher's policyReduction of inertia from conventional generation is rising questions towards grid-operators about the reliability of generations in the upcoming years. The loss of synchronous generators in addition to the massive increase ... -
Review of multiport power converters for distribution network applications
(2024-10-01)
Article
Open AccessMultiport power converters integrate three or more energy devices into a single (potentially highly controllable and efficient) hub. These characteristics suggest that multiport power converters may be valuable for the ... -
Control strategy for a triple active bridge converter: a generalized average model approach
(Institute of Electrical and Electronics Engineers (IEEE), 2023)
Conference report
Restricted access - publisher's policyThis paper presents a control strategy for the triple active bridge (TAB) converter based on the generalized average model (GAM). The TAB operation is summarized and the GAM derivation for the TAB is presented in detail. ... -
Detection of abnormal photovoltaic systems’ operation with minimum data requirements based on Recursive Least Squares algorithms
(2024-05)
Article
Open AccessIn the last years, the massive deployment of new photovoltaic (PV) power plants has launched the connection of PV inverters to the electrical network. A single medium-sized ground-mounted PV plant may have thousands of ... -
Data-driven techniques to improve the reliability of low voltage electricty networks through dynamical evaluation of non-technical losses
(Institute of Electrical and Electronics Engineers (IEEE), 2023)
Conference lecture
Restricted access - publisher's policyThe paradigm of electrical networks is changing rapidly due to the large penetration of renewable energy sources and other distributed generation and storage assets. The variability in the generation profile hinders the ... -
Detection of abnormal operation of PV inverters based on regressive prediction models with recursive least squares training
(Institute of Electrical and Electronics Engineers (IEEE), 2024-01-01)
Article
Open AccessThe large scale integration of photovoltaic (PV) power plants has launched the massive deployment of PV inverters. In fact, just a single multi-MW PV plant may have thousands of them, which can be also found isolated in ... -
Control of a three-phase active transformer integrating energy storage
(2023-06-12)
Article
Open AccessThe high penetration of distributed energy sources is changing the paradigm of electrical networks control and management. Nowadays, power conversion systems associated to green energy plants are not only required to deliver ... -
Grid-forming controller based on virtual admittance for power converters working in weak grids
(Institute of Electrical and Electronics Engineers (IEEE), 2023-07)
Article
Open AccessThe high penetration of distributed energy resources, based on power electronics, is giving rise to stability issues in the electrical network, as initially those plants were not required to provide either voltage or ... -
Virtual admittance PLL structure for grid-forming power converters in microgrids
(2020)
Conference lecture
Restricted access - publisher's policySynchronization plays a fundamental role in connecting power electronic converters with the grid. Conventionally, the synchronous reference frame phase-locked loop (SRF-PLL) has been widely used to estimate the grid phase ... -
A growing self-organising maps implementation for coherency identification in a power electronics dominated power system
(2020)
Conference lecture
Restricted access - publisher's policyThe presence of power electronics in today’s power systems strengthens due to the wider integration of renewable energy and energy storage systems. Subsequently, the dynamical response becomes harder to model and understand. ... -
Active transformer functionalities including an energy storage system
(Institute of Electrical and Electronics Engineers (IEEE), 2021)
Conference lecture
Restricted access - publisher's policyThis paper presents a series converter in an application with a Custom Power Active Transformer (CPAT) which is a power electronics integrated transformer providing services to the grid and load. The active transformer ... -
Inertia emulation in power converters with communication delays
(2020)
Conference report
Restricted access - publisher's policyEmulating inertia using power converter has been an effective way to provide additional inertia to power electronic dominated power systems. Currently, the control algorithms for emulating inertia have been proposed ...
