Resiliency planning of distribution network using of active distribution network partitioning. [PDF]

Heliyon
Today, micro-grids (MGs) include all kinds of energy storage systems (ESSs), wind turbines (WTs), photovoltaic (PV), combined heat and power (CHP), etc., also demand response are active on the demand side. In this paper, single-level robust methods for partitioning and planning the active distribution network (ADN) into several MGs are presented ...

A Deadbeat PI Controller With Modified Feedforward for PMSM Under Low Carrier Ratio

IEEE Access, 2021
When the permanent magnet synchronous motor (PMSM) operates at low carrier ratio, the decoupling capability and dynamic performance of the proportional-integral (PI) controller are limited by the digitization delay.

Troubleshooting Distributed Network Emulation

2023 26th Conference on Innovation in Clouds, Internet and Networks and Workshops (ICIN), 2023
Distributed network emulators allow users to perform network evaluation by running large-scale virtual networks over a cluster of fewer machines. While they offer accessible testing environments for researchers to evaluate their contributions and for the community to reproduce its results, their use of limited physical network and compute resources can
