A new method for stability assessment of inverter-based microgrids is presented in this paper. It leverages the notion of critical clusters -- a localized group of inverters with parameters having the highest impact on the system stability. The spectrum of the weighted network admittance matrix is proposed to decompose a system into clusters and rank them based on their distances from the stability boundary. We show that each distinct eigenvalue of this matrix is associated with one cluster…

Stability Evaluation of Interconnected Multi-Inverter Microgrids Through Critical Clusters

This paper proposes the notion of “critical cluster” in inverter based droop controlled microgrids, thus representing the neighborhood of the distributed generation units that determines the small

A framework for development of universal rules for microgrids stability and control

TLDR

Model Order Reductions for Stability Analysis of Islanded Microgrids With Droop Control

TLDR
A mathematical model for islanded microgrids with linear loads and inverters under frequency and voltage droop control is proposed and shows that the currents' dynamics influence the stability of the microgrid, particularly for high values of the frequency Droop control parameters.

Modeling, Analysis and Testing of Autonomous Operation of an Inverter-Based Microgrid

The analysis of the small-signal stability of conventional power systems is well established, but for inverter based microgrids there is a need to establish how circuit and control features give rise

TLDR
A computationally efficient and accurate reduced-order model is proposed for modeling inverter-based microgrids that has a structure similar to quasi-stationary model and at the same time properly accounts for the effects of network dynamics.

Plug-and-play control of AC islanded microgrids with general topology

TLDR
This paper introduces an approximate KR algorithm, still capable to represent exactly the asymptotic periodic behavior of electric signals in balanced RL line networks with balanced and unbalanced loads, and its use for designing PnP controllers in a 21-bus ImG derived from an IEEE test feeder.

Voltage Stability and Reactive Power Sharing in Inverter-Based Microgrids With Consensus-Based Distributed Voltage Control

TLDR
It is shown that the choice of the control parameters uniquely determines the corresponding equilibrium point of the closed-loop voltage and reactive power dynamics, and a necessary and sufficient condition for local exponential stability of that equilibrium point is given.

TLDR
A method for tuning inverter control parameters (namely droop coefficients and virtual impedance) that guarantees stable operation under arbitrary interconnection of inverters to the grid is presented.
