The emerging smart-grid and microgrid concept implementation into the conventional power system brings complexity due to incorporation of various renewable energy sources non-linear inverter-based devices. occurrence frequent outages may have a significant negative impact on nation’s economic, societal, fiscal standing. As result, it is essential employ sophisticated monitoring measuring techno...

This paper presents a novel fault location method for series compensated transmission lines. It is established based on synchronized voltages sampling and Thevenin impedance from both ends of series compensated transmission line. The method is based on the use of phasor measurement units (PMU) technology which is aimed to be independent of current measurements, fault type, fault resistance, fau...

Ever-increasing energy demand has led to geographic expansion of transmission lines and their complexity. In addition, higher reliability is expected in the transmission systemsdue to their vital role in power systems. It is very difficult to realize this goal by conventional monitoring and control methods. Thus, phasor measurement units (PMUs) are used to measure system parameters. Although in...

Abstract One challenge in Wide Area Measurement System is to design a reliable network which assures data availability. The availability of Phasor Unit (PMU) networks depends on two factors: 1‐Reliable measurements depend performance PMUs and transmission branches, 2‐Reliable the reliability communication used transfer from Data Concentrators (PDCs) control centre. can be improved by choosing p...

In this paper we describe an advanced hardwarein-loop simulation facility for real-time demonstration and validation of power system monitoring and control algorithms, recently constructed at NC State University. This facility integrates a real-time power system emulation lab with the GENI network and its associated cloud testbeds. The dynamic responses from the power system emulator are captur...

The need for Phasor Measurement Units (PMUs) is rising as renewable energy sources become more prevalent in power networks since the rate of change frequency being deteriorated. Appropriate and accurate network measurements are a requirement precise monitoring control system. This paper presents low-cost PMU development, so-called PhasorsCatcher, networks, using sufficient but straightforward m...

With the increasing penetration of converter-based renewable resources, different types dynamics have been introduced to power system. Due complexity and high order modern system, mathematical model-based inertia estimation method becomes more difficult. This paper proposes two novel machine learning assisted methods based on long-recurrent convolutional neural (LRCN) network graph (GCN) respec...

Limited data feedback rate, e.g. 1-10 samples per second instead of 25-60, causes adverse effect on wide-area damping control (WADC). An observer driven system copy (OSC) approach is suggested here to deal with low data rates. The basic idea is to use the knowledge of nominal system dynamics to approximate the actual system behavior during intervals when data from phasor measurement units (PMUs...
