This paper presents a novel approach for realizing coordinated control of Distributed Energy Resources (DERs) based on cloud-hosted and edge-hosted digital twins (DTs) DERs. DERs are playing an increasingly important role in supporting the frequency regulation power systems with massive integration renewable resources. However, due to significant differences DERs’ capability characterist...

This paper presents a novel Loss of Mains (LoM) protection method based on IEC 61850 Manufacturing Messages Specification (MMS) protocol over wireless Global System for Mobile Communication (GSM) based access point name (APN) mechanism. LoM or anti-islanding protection is a key requirement in modern power distribution grids where there is significant amount of distributed energy resources (DER)...

In recent years, resilience enhancement of electricity distribution systems has attracted much attention due to the significant rise in high-impact rare (HR) natural event outages. The performance post-event restoration after an HR is effective measure for a resilient network. this paper, multi-objective model presented improving first objective function, load shedding process minimized. As sec...

Low voltage ride through (LVRT) is a solution to increase the tolerance of distributed energy resources (DERs) against sags. However, possibility DERs trip according present grid codes exists. Such trips do not have substantial local effect but are essential for transmission systems with connected DER-penetrated distribution networks (DPDNs). This paper investigates an analytical framework see ...

The connection of distributed energy resources (DERs) to distribution feeders can significantly increase the operational flexibility system operators. Local feedback control schemes (such as Volt/VAr droop curves) are a cheap, scalable, and communication-free solution DERs in active grids. However, these controllers interfere detrimentally with each other when they act on multiple connected sam...

This paper introduces a new framework of deep reinforcement learning based protective relay design in power distribution systems with many distributed energy resources (DERs). With increasing penetration electronically-interfaced resources, conventional overcurrent relays’ performance is rendered less effective due to the two-way uncertainties flow patterns. In this paper, machine learning-base...
