Abstract

This article proposes a supplementary controller for inverter based distributed generations (DGs) to damp out the power and frequency oscillations that may occur following the change in the operation mode of Microgrids (MG). The proposed supplementary controller is implemented in synchronous reference frame (SRF) using the port-controlled Hamiltonian modeling strategy. The proposed supplementary controller can be readily integrated into the existing controllers that are commonly used as the main controllers in inverter-based Distributed Generators (DGs). The proposed supplementary controller is designed in such a way that improves the response of DGs during the system oscillations without affecting the steady state reference tracking performance of the DGs. The proposed supplementary controller is able to inject damping to both relative-degree-one (RD1) and higher-relative-degree (HRD) states of the inverters. The effectiveness of the proposed supplementary control for enabling seamless transitions between operation modes of MGs is demonstrated using a set of time domain simulations in a multi-source MG.
