Control and protection of a microgrid connected to utility through back-to-back converters
Electric Power Systems Research, 2011 This paper discusses the control and protection of a microgrid that is connected to utility through back-to-back converters. The back-to-back converter connection facilitates bidirectional power flow between the utility and the microgrid.

10th IET International Conference on Developments in Power System Protection (DPSP 2010). Managing the Change, 2010
The paper analyses the existed protection of microgrid. And in order to meet the requirements of microgrid protection, a novel protection is presented in this paper. The protection based on local information without the need of communication, uses current traveling waves to identify faulted feeder, and the bus bar voltages to determine a event caused ...

Impacts of microgrid on protection of distribution networks and protection strategy of microgrid
2011 International Conference on Advanced Power System Automation and Protection, 2011In order to make more rational and effective use of distributed generation (DG), microgrid has been put forward. However, the connection of microgrid has a fundamental impact on the protection of distribution network. A brief introduction of the structure of microgrid was given, and the potential impact of DG on the protection and autoreclosing was ...

An improved protection strategy for microgrids
IEEE PES ISGT Europe 2013, 2013Microgrids (MG) enable the integration of low capacity renewable energy resources with distribution systems. A recently proposed protection scheme for MGs utilising undervoltage, High Impedance Fault (HIF) detection, directional protection modules, and communication links significantly reduces the fault clearing time compared to previous schemes.

Challenges In Protection Of Microgrid Systems
Intelligent Automation & Soft Computing, 2010Abstract Microgrids comprise low voltage distribution systems with distributed energy resources (DER) and controllable loads which can operate connected to the medium voltage grid or islanded in a controlled coordinated way. This concept aims to move from “connect and forget” philosophy towards a full integration of DERs.

Microgrid protection: An overview of protection strategies in North American microgrid projects
2017 IEEE Power & Energy Society General Meeting, 2017Microgrids have been proposed as an attractive solution to harness the benefits offered by distributed energy resources (DERs). However, despite their advantages, microgrids introduce new challenges to electric grids. In particular, they can impact conventional protection practices in distribution systems.

Protection Issues in Microgrids and Multi-microgrids
2017Conventional power generation from fossil fuels contributes to the problems of climate change and low energy efficiency. These problems can be partly addressed by interconnecting distributed generators (DGs) with the distribution system to supply electric power from renewable energy resources such as photovoltaic (PV), wind, biomass, and fuel cells ...

Adaptive Protection System for Microgrids: Protection practices of a functional microgrid system
IEEE Electrification Magazine, 2014Distributed energy resources (DERs) offer on-site generation at consumption points, which are expected to change the conventional concept of central power generation. DER integration reduces transmission losses and enhances the operation reliability of distribution systems. However, distribution systems are traditionally designed as passive networks in
