With depletion of conventional sources of energy such as coal and oil, the world and its people must look to a new and renewable source of energy to sustain our way of life. One way is to harness the energy of the wind. Wind energy is a source of energy that is free, non-polluting, renewable and unlimited. The major positive outcome from the use of...

Due to the growth of distributed energy resources (DER) and new customer devices, there is currently a two-way energy flow in electric distribution grids. As a result, there is increasing tendency in full observation tools for grid protection and management. Micro Phasor Measurement Unit (μPMU) measures highly precise time-synchronized current and...

Integration oflarge-scale renewable energy (RE) sources in particular, photovoltaic (PV) sources into the electric grid introduces current and voltage harmonics due to power electronics devices as well as inverter connected into the RE sources. Ensuring adequate harmonics in the line currents of RE integrated power system is one of the biggest chal...

At present there is a two-ways energy flw in electric distribution grids due to the growth of distributed energy resources (DER) and new customer devices. So, there is growing interest in full observation tools for grid control, protection, etc. Micro Phasor Measurement Unit (µPMU) measures highly accurate time-synchronized samples of current and v...

The smart distribution grids monitoring process refers to consistently collect data related to all distributed resources conditions. The dynamic nature of distribution grid systems makes the monitoring tools to be essential in utilizing different types of distributed resources and providing smart services to users. This paper gives a general overvi...

Today’s electric power distribution systems with development of distributed energy resources introduce variability, uncertainty, and opportunities to recruit diverse resources for grid services. Multiple resources on each feeder have more complex impacts on the circuit behavior that can be observed with voltage and current phase angle variations. M...

This paper presents wavelet based analysis for transmission line fault location. Faults in power transmission lines cause transients that travel at a speed close to the speed of light and propagate along the line as traveling waves (TWs). Traveling wave theory is utilized in capturing the travel time of the transients along the monitored lines betw...
