In Germany due to the continuous high expansion of the intermittent power supply capabilities of wind turbines and photovoltaic systems, the operational modes of thermal generation units will be influenced essentially until 2020 and beyond. With the renewable energy sources (e.g. wind power (WP) and photovoltaic (PV)) in power system increase, the conventional power plants on line will be replaced by WP and PV. Thus, Read More

There has been a rapid increase in wind turbine connection to distribution and transmission networks in recent years. With individual wind turbines approaching the multi - MW and the wind plants, as a result, approaching the output rating of conventional power plants, a deeper understanding of their potential impacts on interactions with the bulk electric power system is needed. The increased penetration makes the power net Read More

HIFs can remain masked and undetected by classical ground and current based relays for long periods of time, causing high risk of injury to surrounding wildlife and personnel. One of the hardest and complex problems facing nowadays is the detection of high impedance faults on electrical distribution systems. This paper presents a classification and detection relaying scheme for fast accurate detection and identifi Read More

Integration of photovoltaic (PV) energy into the electrical power system is increasing with the development in the PV technology. Transformer magnetizing inrush current problem occurs due to switching the trans-former into the service. This paper proposes an inrush current reduction technique using the PV power. The proposed procedure applies an opposite flux on the transformer using the PV power, then connect th Read More

This paper presents the architecture, functionality, and field evaluation of a newly developed real-time advanced warning system using dedicated short range communication (DSRC) based vehicle-to-vehicle (V2V) communication without the need for a DSRC roadside unit to control the system operation. The developed system dynamically acquires important traffic parameters such as starting location of congestion (SLoC), endi Read More

This work presents a patent technique for digital image compression using wavelet theory and a Huffman CODEC system that can be used for bandwidth reduction in digital transmission and to decrease time of data transmission in channel information. A twodimensional 1-channel multiresolution analysis and synthesis structure are implemented. In the transmission, the digital image is processed using quincunx low Read More
