This paper presents a control strategy applied to grid-connected radial microgrids, allowing to coordinate their inverters to regulate the dispatch of the active and reactive powers while concomitantly offering distributed compensation of harmonic currents. Thus, the MG operates as a single-controllable entity, and its power dispatch can support demand response without propagating harmonics to the upstream grid. The effectiveness of the power flow regulation and harmonic mitigation are demonstrated by experimental results in a single-phase MG prototype considering two inverters and multiple loads.
