Abstract—The purpose of planned islanding is to construct a power island during system disturbances which are commonly formed for maintenance purpose. However, in most of the cases island mode operation is not allowed. Therefore distributed generators (DGs) must sense the unplanned disconnection from the main grid. Passive technique is the most commonly used method for this purpose. However, it...

Micro Grid is a contracted distributed AC or DC network. Micro Grid resources are connected to the distributed linear as well as nonlinear loads through power electronics converter to provide an efficient, more reliable and quality power to the distributed loads with reduced co2 emission. Consequently makes full use of low cost generation resources and reduce waste. Interconnected Mode in the M...

Real-time simulations have proven to be an important tool for system analysis because they present robust results that are more similar the dynamics behavior of a real system. The objective this paper is evaluate passive islanding detection methods applied with photovoltaic generation in real-time simulator OPAL-RT©. analyzed Under/Over frequency, voltage, Rate Change Frequency (ROCOF) and Volt...

The correlation coefficient-based (CCB) method of islanding detection has been shown to be highly effective in detecting islands in electric power systems. However, due to the high sensitivity of the method, a number of questions remain regarding its practical applicability. In this paper, three such issues are addressed: immunity of the method to false trips during system-level events, sensiti...

Intentional islanding is a feasible solution to improve the reliability of the smart distribution system with distributed generations (DGs) when the electrical connections between the smart distribution system and upstream network are lost. In this paper, a heuristic method is proposed for the intentional islanding of microgrids. In this method, some practical and important factors such as redu...

Controlled islanding is the last countermeasure for a bulk power system when it suffers from severe cascading contingencies. The objective of controlled islanding is to maintain the stability of each island and to keep the total loss of loads of the whole system to a minimum. This paper presents a novel integrated wide-area measurement systems (WAMS)-based adaptive controlled islanding strategy...
