In the present study, a new method is proposed for early voltage instability detection based on the statistical analysis of the data obtained from PMUs and Micro-PMUs. Although, the use of high sampling rate measurements helps operators to assess the dynamic behaviour of the systems, but it may lead to processing a large volume of data, which is a...

This paper proposes a new application of micro-Phasor Measurement Units (µPMUs) for adaptive coordination of overcurrent relays in microgrids. Mis-coordination of overcurrent relays usually arising from variation of relays fault current and it can cause damage to equipment of network and raise operating costs. Fault current injection and direction...

VSC-HVDC transmission system is going to become the most economical way of power delivery for large and remote offshore wind farms. An accurate and fast fault detection method is necessary to protect sensitive devices of these systems and maintain uninterrupted power delivery. This paper investigates an innovative technique for recognizing DC zone...

This paper presents an algorithm for high impedance fault (HIF) detection by phasor measurement units (PMUs) that are basic elements in wide area monitoring and protection systems (WAMPS). This method uses output current phasors of PMU for detection of HIF. At first, change of current detects by summation of errors between sampled data and estimate...

Nowadays, the growth of AC distribution networks joined to DC transmission is increasing due to renewable energy sources and necessary requirements for conversion of sustainable energy to expendable energy in the main grid. This paper investigates impacts of medium voltage direct current system on transient states of AC distribution system integrat...
