Abstract The emergence of distributed generators has changed the operational mode and fault characteristics distribution network, in a way which can severely influence protection. This paper proposes d-axis-based current differential protection scheme. d-axis inverter-interfaced synchronous are analyzed. criterion using sampling values component is then constructed. Compared to conventional pha...

Parallel connected inverters in islanded mode, are getting momentous attention due to their ability increase the power distribution and reliability of a system. When there different ratings Distributed Generation (DG) units, they will operate parallel connection output voltages, impedance mismatch, or phase that can cause current flow between DG units. The magnitude this circulating sometimes b...

This paper proposes a novel decentralized and communication-less control strategy for frequency voltage regulation in Photovoltaic (PV)-Storage islanded Microgrids (MGs). The developed approach aims at achieving suitable management of the different operational assets PV-Storage MGs providing seamless transitions among them guaranteeing continuous effective power supply to loads. Local inverter ...

This paper proposes an inductor current sensorless control strategy based on modified virtual synchronous generator (VSG) method for single-phase inverter-interfaced microgrid application. Firstly, the outer power loop with Q-U integral term is presented output reactive enhancement, and inner voltage regulation luenberger state observer proposed to reduce sensor. Meanwhile, in order improve res...

This paper proposes a power sharing control scheme for electronics interfaced distributed generation to attain accurate harmonic dispatch as well unbalanced sharing. The proposed controller is composed of two main blocks: 1) unit, which leads an sharing, and 2) individual triple-droop units separately applied the unit each phase, properly provide For this purpose, virtual conductance concept de...

In this paper, an attempt has been made to introduce a new control strategy including Plug-in Hybrid Electric Vehicle (PHEV) and Diesel engine generator to control the voltage and frequency of autonomous microgrids. The proposed control strategy has multiple advantages over the recent control methods in microgrids. The proposed method applies the primary and secondary frequency control strategy...

This paper addresses the cybersecurity of hierarchical control AC microgrids with distributed secondary control. The false data injection (FDI) cyberattack is assumed to alter operating frequency inverter-based generators (DGs) in an islanded microgrid. For consisting grid-forming inverters a manner, attack on one DG deteriorates not only corresponding but also other DGs that receive corrupted ...
