Fault characteristics and protection scheme of islanded microgrid

New Protection Scheme for Internal Fault of Multi-Microgrid

Multi-microgrid has many new characteristics, such as bi-directional power flows, flexible operation modes and variable fault currents with different control strategy of inverter interfaced distributed generations (IIDGs). All these featuring aspects pose challenges to multi-microgrid protection. In this paper, current and voltage characteristics of different feeders are analyzed when fault occ...

Fault-tolerant Control of a Master Generation Unit in an Islanded Microgrid

Two model-based fault-tolerant control design strategies are presented for a Diesel Engine Generator (DEG) working as a master generation unit in an islanded microgrid consisting of a hybrid wind-diesel-photovoltaic power system with a Battery Storage System (BSS). A Model Predictive Control (MPC) scheme and a Model Reference Adaptive Control (MRAC) scheme have been selected for precise and sta...

An Implementation of Enhanced Power Sharing Scheme for Islanded Microgrid using VPI Controller

This project deals with the application of distribution generation with energy storage system connected to the low– voltage microgrid by coupling inverter for simultaneous energy management and other aucillary services that include the compensation of power quality disturbances. To address inaccurate power sharing problems in autonomous islanding microgrid, an enhanced droop control method thro...

Fault Detection and Location in DC Microgrids by Recurrent Neural Networks and Decision Tree Classifier

Microgrids have played an important role in distribution networks during recent years.  DC microgrids are very popular among researchers because of their benefits. Protection is one of the significant challenges in the way of microgrids progress. As a result, in this paper, a fault detection and location scheme for DC microgrids is proposed. Due to advances in Artificial Intelligence (AI) and s...
