Passivity-based Voltage and Frequency Stabilization in AC microgrids

Giancarlo Ferrari Trecate, Pulkit Nahata

In this paper, we investigate the stability of an islanded AC microgrid (ImG) composed of Distributed generation units (DGUs), dynamic power lines, and loads. Each DGU is equipped with a local controller to ensure desired voltage and frequency in the ImG. ...

Voltage Stabilization in MVDC Microgrids Using Passivity-Based Nonlinear Control

Giancarlo Ferrari Trecate, Pulkit Nahata, Andrea Martinelli

This paper investigates the application of passivity-based nonlinear control to the problem of primary voltage stabilization in medium-voltage DC microgrids (MVDC mGs) given by the interconnection of nonlinear distributed generation units (DGUs) and power ...

A Passivity-Based Approach to Voltage Stabilization in DC Microgrids

Giancarlo Ferrari Trecate, Pulkit Nahata, Michele Tucci, Raffaele Soloperto

We consider the application of passivity theory to the problem of voltage stabilization in DC microgrids (DCmGs) given by the interconnection of Distributed Generation Units (DGUs), dynamic RL lines, and loads. We first provide a novel result on stable int ...

A Decentralized Switched System Approach to Overvoltage Prevention in PV Residential Microgrids

Pulkit Nahata, Florian Dörfler

In this paper, we consider the problem of overvoltage arising in PV residential microgrids due to excessive power injection into the grid by the PV generators. We propose a decentralized switched controller to curtail excess active power in order to avoid ...
