Shift factor-based SCOPF topology control MIP formulations with substation configurations [PDF]

open access: yes, 2017
Topology control (TC) is an effective tool for managing congestion, contingency events, and overload control. The majority of TC research has focused on line and transformer switching. Substation reconfiguration is an additional TC action, which consists

Implementation and Critical Analysis of the Active Phase Jump with Positive Feedback Anti-Islanding Algorithm

open access: yesEnergies, 2022
The protection against the unintentional islanding of Grid-Tied inverters is an important electrical security issue addressed by the main Standards. This concern is justified in face of the fact that unintentional islanding can lead to abrupt variations ...

An islanding detection method for multi-DG systems based on high-frequency impedance estimation [PDF]

open access: yes, 2017
Active islanding detection methods are generally employed for grid-connected inverter-based Distributed Generation (DG). However, there might be mutual influences and power quality issues caused by the disturbance signal when multiple inverters are ...

Universal and Seamless Control of Distributed Resources-Energy Storage for all Operational Scenarios of Microgrids [PDF]

open access: yes, 2017
This paper proposes one control paradigm that can operate in both grid-connected and islanded modes, hence, does not need any sort of islanding detection method. The proposed method automatically and seamlessly rides-through a fault on the grid side, and
