Design of Adaptive Distributed Secondary Control Using Double-Hidden-Layer Recurrent-Neural-Network-Inherited Total-Sliding-Mode Scheme for Islanded Micro-Grid

IEEE Access, 2022
This study proposes an adaptive double-hidden-layer recurrent-neural-network (DRNN)-based distributed secondary control (ADRNN-SC) scheme for the voltage restoration and the optimal active power sharing in an islanded micro-grid (MG).

Centralized and Distributed Multi-Region Traffic Flow Control

, 2020
In this paper, centralized and distributed multi-region perimeter flow control approaches are proposed for congestion avoidance in urban networks. First, multi-region network dynamics are modeled with Macroscopic Fundamental Diagrams (MFDs) and necessary

A unified distributed hierarchal control of a microgrid operating in islanded and grid connected modes

IET Renewable Power Generation, 2023
To guarantee an uninterruptable power supply, a microgrid must be able to operate in both islanded and grid‐connected modes. Hence, it is required to synchronize the voltage phasor of the point of common coupling of the microgrid with the utility grid ...

Consensus-Based Intelligent Distributed Secondary Control for Multiagent Islanded Microgrid

International Transactions on Electrical Energy Systems, 2023
Isolated microgrids (MGs) face challenges in performance stability and active/reactive power sharing as a result of frequency/voltage deviations and mismatched line impedance issues. In this paper, a consensus-based multiagent system (MAS) is proposed as

Distributed Finite-Time Secondary Control for DC Microgrids With Virtual Impedance Arrangement

IEEE Access, 2019
In direct current (DC) microgrids, the accurate current sharing could be achieved by regulating the virtual impedance (droop coefficient) and the output voltage average value of each distributed generator (DG) could be restored by regulating the voltage ...
