Controle hierárquico distribuído com separação de atribuições para paralelismo de UPS
(Universidade Federal de Santa MariaBrasilEngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia ElétricaCentro de Tecnologia, 2021-06-19)
This work presents a distributed hierarchical control strategy applied to the parallelism
of UPSs. A dynamic approach with separation of concerns is proposed for the
secondary control, where a named grid forming inverter ...
roop-controlled inverters small-signal impedance characterization for stability studies
(Universidad de Chile, 2019)
Microgrids are one of the key technologies to facilitate the integration of large amounts of renewable generation technologies to the main grid. The main power supplies inside the microgrid are power electronic devices ...
Secondary Control Strategies for Frequency Restoration in Islanded Microgrids with Consideration of Communication Delays
(2016)
One of the well-known methods to share active and reactive power in microgrids (MGs) is droop control. A disadvantage of this method is that in steady state the frequency of the MG deviates from the nominal value and has ...
A Control Algorithm Based on the Conservative Power Theory for Cooperative Sharing of Imbalances in Four-Wire Systems
(Institute of Electrical and Electronics Engineers Inc., 2019)
© 1986-2012 IEEE. A cooperative control scheme based on the conservative power theory (CPT) is proposed, which can share imbalances in three-phase four-wire droop-controlled systems. By utilizing the CPT, the balanced, ...
