Centralised multimode power oscillation damping controller for photovoltaic plants with communication delay compensation
Jankovic, Njegos; Roldan Perez, Javier; Prodanovic, Milan; Rouco Rodríguez, Luis (2024-03-01)Low-frequency oscillations are an inherent phenomena in transmission networks and renewable energy plants should be configured to damp them. Commonly, a centralised controller is used in PV plants to coordinate PV generators ... -
Coordination of distributed resources for frequency support provision in microgrids
Morán Río, Diana Patricia; Anta Martínez, Adolfo; Roldan Perez, Javier; Prodanovic, Milan; García Cerrada, Aurelio (2024-01-01)To address the reduction of system inertia, transmission system operators are now requesting converter-interfaced generators (CIGs) to participate in frequency support services. Microgrids (MGs) and virtual power plants have ... -
Enabling the seamless coordination and synchronization of microgrids using batteries
Morán Río, Diana Patricia; Roldan Perez, Javier; Prodanovic, Milan; García Cerrada, Aurelio (IEEE Italy Section (Madrid, España), 2023-08-03)Microgrids (MGs) have become a commonly used way for renewable energy sources (RESs) integration in electrical distribution systems. These MGs are formed of a mix of RESs and batteries that can operate either in grid-forming ... -
Finite-gain repetitive controller for harmonic sharing improvement in a VSM microgrid
Roldan Perez, Javier; Prodanovic, Milan; Rodríguez Cabero, Alberto; Guerrero, Josep M.; García Cerrada, Aurelio (2019-11-01)Electronic power interfaces are commonly used in microgrids for renewable energy integration and a control method based on a Virtual Synchronous Machine (VSM) represents an attractive alternative to conventional approaches. ... -
Influence of the phase-locked loop on the design of microgrids formed by diesel generators and grid-forming converters
Morán Río, Diana Patricia; Roldan Perez, Javier; Prodanovic, Milan; García Cerrada, Aurelio (2022-05-01)In recent years, Microgrids (MGs with renewable energy sources, diesel gen-sets and droop-controlled converters have been increasingly used to guarantee the continuity of power supply in remote areas. Renewable energy ... -
LTCL-Filter active-damping design considerations for low-switching-frequency grid-tied VSCs
Roldan Perez, Javier; Avila Martinez, Regulo Enrique; Rodríguez Cabero, Alberto; Prodanovic, Milan; Bueno Peña, Emilio José (Institute of Electrical and Electronics Engineers; IEEE Industrial Electronics Society (Washington, Estados Unidos de América), 2018-10-21)Most electronic devices are connected to the grid by using power electronics converters and, in order to reduce the filter size and cost, novel filter topologies are being proposed in the literature. For high-power ... -
Multimode power oscillation damping controller synthesis using vector fitting
Jankovic, Njegos; Roldan Perez, Javier; Prodanovic, Milan; D'Arco, Salvatore; Suul, Jon Are; Rouco Rodríguez, Luis (Institute of Electrical and Electronics Engineers; Institute of Electrical and Electronics Engineers (Belgrado, Serbia), 2023-06-29)Low-frequency oscillations in power systems have been commonly damped by power system stabilisers based on lead-lag transfer functions. These stabilisers can be implemented in the control loops of synchronous generators ... -
Power oscillation damping method suitable for network reconfigurations based on converter interfaced generation and combined use of active and reactive powers
Jankovic, Njegos; Roldan Perez, Javier; Prodanovic, Milan; Suul, Jon Are; D'Arco, Salvatore; Rouco Rodríguez, Luis (2023-07-01)Power system stabilisers (PSSs) are commonly used in synchronous generators for damping low-frequency oscillations. However, many of these machines have been replaced by converter-interfaced generators (CIGs), such as those ... -
Small-signal analysis of a microgrid with secondary control including the dynamics of primary control and communication delays
Morán Río, Diana Patricia; Roldan Perez, Javier; Prodanovic, Milan; García Cerrada, Aurelio (Institute of Electrical and Electronics Engineers Power and Energy Society; Universidad de Novi Sad (Novi Sad, Serbia), 2022-11-28)Microgrids (MGs) facilitate the integration of distributed energy resources (DERs) in electrical grids. To coordinate the operation of these DERs, a three-level hierarchical control is commonly used. In general, different ...
