Reactive Power Sharing Analysis in Islanded AC Microgrids

Abstract

Primary regulation of islanded Microgrids is one of the most relevant topics in an academic and industrial world. IEEE Std 1547-2018 defines the functionalities of GridSupporting inverters and one of the control goals is the correct reactive power sharing. This paper focuses the attention on the performance of the conventional droop technique in the control of reactive power flows and voltage. After defining the MG structure, a detailed mathematical model for the study of the problem is presented in order to carry out a MG parameters and a regulators parameters sensitivity analysis.
