This study proposes an adaptive nonlinear controller based on advanced nonlinear
disturbance observer (ANDO) and passivity-based control (PBC) to ensure the stability of a …

Constant power loads (CPLs) often lead to system instability and voltage collapse. This
paper analyzes the existence and stability of equilibrium of meshed DC microgrids with …

Voltage collapse is a critical form of system instability in power systems, occurring when
power generation is unable to meet power demand, resulting in considerable socio …

With high penetrations of renewable generation and variable loads, there is significant
uncertainty associated with power flows in dc networks such that stability and operational …

This paper studies the power flow feasibility of DC power grids with constant-power loads.
We introduce and motivate the concept of Braess' paradox for power flow feasibility, and …

With the widespread adoption of switched power converters within the power grid as both
sources and sinks, the necessity arises for establishing verifiable stability conditions. We …

Direct current (DC) networking microgrids have gained prominence as a means to integrate
renewable energy sources and enhance system resilience. However, these types of …

In this article, we study the monitoring and control of long-term voltage stability considering
load tap changer (LTC) dynamics. We show that under generic conditions, the LTC …

Due to financial limitations, power systems are being operated closer to their stability
boundaries. Voltage stability analysis is crucial to preserve a power system's equilibrium …
