This paper utilizes the Newton Raphson (NR) iterative algorithm to solve a detailed heat balance equation for overhead transmission conductors, for the purpose of calculating a Dynamic Line Rating or temperature-dependent impedance using real-time or

In this paper, large-signal Lyapunov-based stability analysis is performed on an inverter-based microgrid. Most microgrid stability studies have been based on small-signal stability by using linearization techniques. This paper produces the large-sig

The transient stability of inverter-based microgrids is important given the low inertia of microgrids especially in islanded mode. However, as a prerequisite to understanding transient stability of such microgrids, the transient stability of individu

Microgrid stability studies have been largely based on small-signal linearization techniques. However, the validity and magnitude of the linearization domain are limited to small perturbations. Thus, there is a need to examine microgrids with large-s

The recent past has seen an influx of new generator interconnection to the power grid. Some of these new generator interconnections occur at places where there isn’t enough transmission capability and hence get curtailed or penalized during the rea

This paper presents seven nonlinear mathematical models of a dc/ac droop controlled inverter connected to an infinite bus. These models are produced using the singular perturbation method to decompose a previously proposed 13th order nonlinear model.
