Special issue on developing and implementing smart grids : novel technologies, techniques and models
Novel protection approach for MV microgrid
The amount of distributed generation (DG) connected to medium voltage (MV) networks is expected to increase continuously. This trend creates a good opportunity to use MV feeders as microgrids. Normally ...
Sensitivity analysis of frequency and voltage stability in islanded microgrid
This paper studies the voltage and frequency stability of an islanded microgrid and the sensitivity of these quantities to certain changes in system configuration. In conventional power systems the system frequency ...
Voltage and current THD in microgrid with different DG unit and load configurations
After microgrid transition from the normal operation to the islanded operation the system impedance changes considerably and it affects on the harmonic voltages of the microgrid. In this paper the voltage ...
Fault type and location detection in islanded microgrid with different control methods based converters
In this paper the fault type and location detection in an islanded low voltage (LV) distribution network based microgrid with converters applying different control methods is studied. In the ...
Protection system for future LV microgrids
Traditional protection of low voltage (LV) network will not be applicable for future LV microgrids and new adaptive protection system must be developed. In this paper adaptive protection system for LV microgrid during ...
