In this article, a novel cooperative secondary voltage/frequency control considering time-varying delays and noises in fading channels is presented for an autonomous alternating current (AC) voltage sourced-based converter (VSC)-based microgrid (MG), including inverter-interfaced distributed generations (DGs). Fading phenomenon makes complex random fluctuations on the frequency of every DG rece...

The growing importance of Microgrid in future power systems highlights critical challenges like microgrid control and stability. An islanded including distributed generations (DG), energy storage (ESS), different types loads (static or dynamic) is prone to instability. whole system must be analyzed designed operate within stable regions. This study models an inverter-interfaced which supplies s...

In this paper an analytical design method is proposed for constant voltage controlled inverter based DG with frequency dependent ZIP–Exponential static load model to obtain proper inverter output control and successful islanding detection. The proposed technique is aimed to eliminate the dependency of DG operation point on anti-islanding performance which is unavoidable in case of traditional c...

This paper presents the modeling and simulation of a proton exchange membrane fuel cell (PEMFC) generation system for off-grid and on-grid operation and configuration. A fuel cell DG system consists of a fuel cell power plant, a DC/DC converter and a DC/AC inverter. The dynamic model for fuel cell array and its power electronic interfacing are presented also a multi-input single output (MISO) D...

The microgrid (MG) is a popular concept to handle the high penetration of distributed energy resources, such as renewable and storage systems, into electric grids. However, integration inverter-interfaced generation units (IIDGs) imposes control protection challenges. Fault identification, classification isolation are major concerns with IIDGs-based active MGs where IIDGs reveal arbitrary imped...

The increasing penetration of inverter-based distributed generations (DGs) significantly affects the fault characteristics of distribution networks. Fault analysis is a keystone for suitable protection scheme design. This paper presents the modelling methodology for distribution networks with inverter-based DGs and performs fault simulation based on the model. Firstly, a single inverter-based D...

This paper focuses on the problem of voltage control of islanded inverterinterfaced microgrids consisting of several distributed generation (DG) units with parallel structure. The main objectives are to (i) design a decentralized/distributed voltage controller with minimum information exchange between DG units and their local controllers (ii) design a fixed-/low-order dynamic output feedback co...

The aim of this paper is to evaluate the technical feasibility and aspects related to use, a Fuel Cell based Distributed Generation (FC-DG) in the residential singlephase applications with premium voltage quality. The paper presents a new topology of buck-boost inverter, where this single stage transformer-less inverter is employed to energize the residential load. With this new topology, the p...

This article proposes a robust cooperative distributed secondary control strategy for dc microgrids, with the main focus on reducing communication burdens. To this end, we adopt sparsity-promoting consensus-based framework converter-interfaced microgrids consisting of multiple generation (DG) units. The proposed relies less (sparse) information exchange over network and does not require exchang...
