Stabilization of DC MicroGrid Systems Using the Loop-Cancellation Technique

DC Microgrid Protection in the Presence of the Photovoltaic and Energy Storage Systems

In recent years, most of the loads and distributed generations are connected to the AC grid through the power electronic converters. Using the DC grid beside the AC grid can reduce the conversion stages and power losses. Protection of the DC grids is a challenging issue because of the new structures of DC grids and fast transients of the DC faults. This paper studies the protection of the low v...

Analysis of Hybrid AC-DC Microgrid: Z-Inverse Technique

This paper deals with the control scheme of the hybrid grid which lags in some important areas like smooth and fast power transfer in the grid and stable system operation under various conditions. For reliable operation of hybrid grid, the converter plays a crucial role which necessities an efficient control strategy at converter. Z inverse technique has been proposed at the converter in this p...

A Testing Technique of Microgrid EMS using the Hardware-in-the Loop Simulation (HILS) System

A microgrid is composed of distributed power generation systems, distributed energy storge systems, loads as a small scale power system. Generally, the microgrid is operated by an energy management system (EMS). In this paper, a testing technique for a microgrid EMS using the hardware-in-the-loop simulation (HILS) technique is introduced. Especially, the microgrid is composed of multiple buildi...

Control of a DC Microgrid

A microgrid is a part of a distribution network embedding multiple distributed generation systems (mostly nonconventional renewable energy sources like photovoltaic panels, small wind turbines etc.) and storage systems with local loads, which can be disconnected from the upstream network under emergency conditions or as planned. The microgrid concept naturally arose to cope with the penetration...
