Cooperative Control to Suppress Unbalanced and Harmonic Distortion in the Distribution Network With Inverter-Based Distributed Generators

In the contemporary distribution network, unbalanced and harmonic distortions have been considered some major power quality problems, which escalated especially due to high penetration of nonlinear loads. This study first analyzes dispute around distortion restraint grid-connected unbalanced/harmonic current suppression quantitatively proposes a distributed control strategy that facilitates an effective output voltage current, with accurate sharing. Compared majority existing studies only addressing voltage-controlled mode (VCM) inverters, our scheme can also be applied current-controlled (CCM) inverters without adding additional regulation loops. The proposed is independent line parameters robust load changes. corresponding small-signal dynamic model constructed analyze system stability controller hardware-in-the-loop simulations aid in determining outcome strategy.
