Considerations on Communication Infrastructures for Cooperative Operation of Smart Inverters
Dos Santos Alonso, Augusto Matheus; Afonso, Leonardo Carlos; Brandao, Danilo Iglesias; Tedeschi, Elisabetta; Marafao, Fernando Pinhabel (Chapter, 2019)The presence of distributed generation systems spread over low-voltage electrical networks is boosting the development of control methodologies aiming at coordinating and cooperatively managing the existing smart inverters. ... -
Coordinated Control of Distributed Three-and Single-phase Inverters Connected to Three-Phase Three-Wire Microgrids
Brandao, Danilo Iglesias; Savoi, Lucas; Alonso, Augusto Matheus Dos Santos; Liberado, Eduardo Verri; Reis, Geovane; Marafao, Fernando Pinhabel (Journal article; Peer reviewed, 2019)This paper explores the coordinated strategy named Power-Based Control to properly coordinate grid-tied single-and three-phase distributed energy resources in three-phase three-wire microgrids. By means of a narrowband, ... -
Coordinated Control of Parallel Power Conditioners Synthesizing Resistive Loads in Single-Phase AC Microgrids
Alonso, Augusto Matheus Dos Santos; Brandao, Danilo Iglesias; Marafao, Fernando Pinhabel; Tedeschi, Elisabetta (Chapter, 2019)Without proper coordination, power conditioners within microgrids are prone to suffer from resonance phenomena due to the complex and dynamic interactions among the main grid, nonlinear loads and distributed converters. ... -
Distributed Selective Harmonic Mitigation and Decoupled Unbalance Compensation by Coordinated Inverters in Three-Phase Four-Wire Low-Voltage Networks
Dos Santos Alonso, Augusto Matheus; Brandao, Danilo Iglesias; Tedeschi, Elisabetta; Marafao, Fernando Pinhabel (Peer reviewed; Journal article, 2020)Considering the high penetration of distributed generators in low-voltage grids, establishing a coordinated operation of their grid-tied inverters has become imperative to move towards the implementation of smart grids.Yet, ... -
Optimal Multiobjective Control of Low-Voltage AC Microgrids: Power Flow Regulation and Compensation of Reactive Power and Unbalance
Brandao, Danilo Iglesias; Ferreira, Willian; Alonso, Augusto Matheus Dos Santos; Tedeschi, Elisabetta; Marafao, Fernando Pinhabel (Journal article; Peer reviewed, 2019)The presence of single-phase distributed generators unevenly injecting active power in three-phase microgrids may create undesired upstream current unbalance. Consequently, voltage asymmetry and even active power curtailment ... -
Selective Power Conditioning in Two-Phase Three-Wire Systems Based on the Conservative Power Theory
