Interfacing a weak grid imposes challenges on distributed generators (DGs). These include transient frequency and voltage dynamics that can destabilize the system. Accordingly, this paper investigates stiffness based different scenarios of feeding DG connected to grid. Moreover, dynamic effects physical control parameters system’s stability are deeply analyzed evaluated. Specifically, complete ...

In this paper, a new approach is proposed for voltage and current harmonics compensation in grid-connected microgrids (MGs). If sensitive loads are connected to the point of common coupling (PCC), compensation is carried out in order to reduce PCC voltage harmonics. In absence of sensitive loads at PCC, current harmonics compensation scenario is selected in order to avoid excessive injection of...

Abstract Recent development in the small scale power generation using distributed energy resources combined with application of power electronic systems initiated the researchers to the concepts of future power generation technologies such as microgrid. The paper presented involves the control techniques required for microgrid operation and implementation of a simple control strategy in a micro...

Abstract Microgrids (MGs) are characterized by faster dynamics than conventional grid-connected distributions systems. This is in part due to the lack of inertia inverter-interfaced distributed energy resources such as photovoltaic and storage In this context, load considerably affects transient stability performance MGs, especially if disconnected from main grid. The aim paper analyze influenc...

Abstract The grid-connected DC microgrid under the background of high penetrations renewable energy sources and inverter-interfaced devices has characteristics strong nonlinearity poor immunity, which leads to problems large-scale voltage fluctuation instability when suffers large disturbances, it seriously influences security stable operation system. Therefore, a disturbance stability criterio...

Over the past decade, world’s electrical grid infrastructure has experienced rapid growth in integration of grid-edge inverter-based distributed energy resources (DERs). This led to operating concerns associated with reduced system inertia, stability and intermittent renewable power generation. However, advanced or “smart” inverters can provide services such as volt-VAR, frequency-Watt, constan...

Due to disperse nature of renewable energy resources (RES), electricity generation is often taking place in small scale but main drawback is power quality. So to improve power quality issues, integration of renewable energy into the utility grid can be done either at transmission level or the distribution level depending on the scale of generation. The renewable resources like solar energy, win...
