Control and Protection of a Microgrid Connected to Utility Through Back-to-Back Converters [PDF]
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.

Challenges in Microgrid Protection
2019 FISE-IEEE/CIGRE Conference - Living the energy Transition (FISE/CIGRE), 2019Due to the increased complexity of distribution networks and the commitment to offer high quality electricity from distributed generation, in terms of reliability and security, conventional strategies in the design of protection schemes are overcome by the great challenges in maintaining the stability and safety of the microgrid.

A microgrid embraces a low-voltage (LV) distribution grid with distributed energy resources (DER) and controllable loads. In the last years, there has been a growing awareness in exploiting microgrids to facilitate DER integration in electric power systems as well as to improve reliability and power quality in distribution grids.

A review on Microgrid protection
2014 International Electrical Engineering Congress (iEECON), 2014Incorporation of Microgrid (MG) comprising of distributed generators (DGs), in the existing bulk power system has become an inevitable trend. The traditional distribution network designed to operate radially is protected by simple protective devices such as fuses, reclosers and over-current relays (OCRs).

Protective Systems in DC Microgrids
2019The aging power system causes to several grid problems such as intermittency, power quality issues, and blackouts since a few decades. Therefore, the power infrastructure requires serious troubleshooting studies in a wide manner. The distributed generation and integration of large photovoltaic (PV) plants to the existing utility have led to intensive ...

Adaptive Protection for Preserving Microgrid Security
IEEE Transactions on Smart Grid, 2019The low inertia renders renewable-based microgrids ( $\mu$ Gs) more susceptible to incipient faults and makes it more difficult for distributed systems to maintain a reasonable margin for dynamic security. This paper studies the $\mu\text{G}$ security using a three-stage approach to the power system protection.

Adaptive Zonal Protection for Ring Microgrids
IEEE Transactions on Smart Grid, 2017In a fault situation on a microgrid with multiple sources, a ring distribution architecture permits healthy parts of the power distribution network to remain operational while isolating a fault. However, fault localization in a multi-ring power distribution system can be considerably more complex than for a radially distributed network.
