In three-phase unbalanced systems, where the circulation of zero sequence current is
necessary, four-leg converters provide a neutral connection for single-phase or other …

Unbalance or asymmetry in the distribution network is a well‐known power quality issue. In
the modern active distribution system, with the increasing penetration of renewables, this …

This paper presents a droop-based controller for grid-tied three-phase inverters. The
controller allows to regulate the inverter output power while operating grid-tied, to support …

In recent times, microgrids are marking their presence with the electrical grid. They are
capable of meeting increased load demand, alleviate transmission line stress, support …

This article introduces a power controller for three-phase inverters in microgrids that can be
used in three-phase three-wire and three-phase four-wire systems. The controller enables …

Electronic power converters are extensively applied in microgrids to interface distributed
energy resources to the grid. Besides the primary active-power control, electronic converters …

This manuscript describes the operation of a droop-based controller for three-phase
converters in the case of the absence of a neutral connection to the grid. The controller is …

A power and unbalanced-currents controller for three-phase inverters in microgrids is
presented herein. Based on symmetric sequences, it allows tracking positive-sequence …

This paper presents a droop-based controller for grid-tied three-phase inverters. The
controller allows to regulate the inverter output power while operating grid-tied, to support …

Inverter based distributed generators (DGs) in microgrids can be controlled in either of the
centralized, distributed or de-centralized approaches. Droop control involves the control of …
