Plug-and-Play Robust Voltage Control of DC Microgrids

The purpose of this paper is to explore the appli- cability of linear time-invariant (LTI) dynamical systems with polytopic uncertainty for modeling and control of islanded DC microgrids under plug-and-play (PnP) functionality of distributed generations (D ...

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

Florian Dörfler, Pulkit Nahata

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 ...

Advanced Droop Control in Islanded Microgrids Using Dynamic Phasor Models

Alireza Karimi, Christoph Manuel Kammer

A dynamic phasor model for low- and medium-voltage distribution grids is presented. This model accurately represents the transient dynamics of this type of grid, and its low order makes it well suited for control design. A novel fixed-structure, robust con ...

Plug-and-play Voltage Stabilization in Inverter-interfaced Microgrids via a Robust Control Strategy

Alireza Karimi

This paper proposes a decentralized control strategy for the voltage regulation of islanded inverter-interfaced micro- grids. We show that an inverter-interfaced microgrid under plug- and-play (PnP) functionality of distributed generations (DGs) can be cas ...

Plug-and-play design of current controllers for grid-feeding converters in DC microgrids

Giancarlo Ferrari Trecate, Michele Tucci, Raffaele Soloperto, Renke Han

In this paper, we address the problem of synthesizing decentralized current controllers for grid-feeding converters of current-controlled distributed generation units (CDGUs) in dc microgrids (MGs). Notably, a plug-and-play (PnP) design procedure is propos ...

Decentralized Optimal Projected Control of PV Inverters in Residential Microgrids

Florian Dörfler, Pulkit Nahata

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 optimal integral controller to curtail excess active power in order t ...

Real-Time Control of an Ensemble of Heterogeneous Resources

Jean-Yves Le Boudec, Andrey Bernstein, Niek Johannes Bouman

This paper focuses on the problem of controlling an ensemble of heterogeneous resources connected to an elec- trical grid at the same point of common coupling (PCC). The controller receives an aggregate power setpoint for the ensemble in real time and trac ...

Real-Time Power-Reference Tracking Method for PV Converters

Mario Paolone, Lorenzo Enrique Reyes Chamorro

Due to the increasing presence of renewable inertia-less energy sources, power electronics interfaces are required to exploit their flexibility in order to support the overall grid quality of service. One way to achieve this, is that power converters are c ...

Off-grid power not a silver bullet for rural India

Michaël Aklin

A quarter of Indian households have no access to electricity. Swiss researcher Michaël Aklin - who studied the impact of solar microgrids in the country's villages - opines on whether off-grid solar power could change people's lives. ...
