Abstract

Multifunctional inverters are being consolidated as vital devices in electrical microgrids, due to their capacity of adding flexibility to active power injection management, also offering power quality related supplemental ancillary services. Therefore, several approaches based on hierarchical or decentralized methodologies have been proposed to cooperatively coordinate such devices dispersed over microgrids, aiming mainly a global, which focus on the power flow control at a PCC or in a specific node. As a consequence, there remains a gap in the literature regarding alternatives that are able to coordinate inverters under a multiobjective context in microgrids, providing sharing of active, reactive and harmonic electrical quantities, not only striving for a specific goal at the PCC or in a particular node, but also complying with power quality measurements in secondary nodes. Having that in mind, this work intents to study a methodology able to cooperatively control inverters looking at multiple nodal operation goals within a microgrid, under islanded or grid-connected conditions, with single- or three-phase topology, and considering distorted and asymmetrical voltage scenarios. Studies related to the feasibility of some methodologies found in literature, such as the current-based control algorithm, will support the later development of a strategy that expands a distributed coordination approach with a singular target to a multiobjective scope. The assembly of a laboratory scale prototype of a dispatchable microgrid with dispersed inverters is as well planned, aiming at experimentally validating the methodologies developed in this work, also confronting the proposed computational simulations.
