Linear active-power-only DC power flow approximations are pervasive in the planning and control of power systems. However, these approximations fail to capture reactive power and voltage magnitudes, both of which are necessary in many applications to ensure voltage stability and AC power flow feasibility. This paper proposes linear-programming models (the LPAC models) that incorporate reactive ...

The use of Knowledge-Based Systems (KBS) in Power System Control Centres is today recognised as a good way to provide Control Center operators with decision support tools. Power Systems can be considered as an important field of application of Knowledge-Based Systems not only because of the high number of applications but also because of the challenge that Power System application usually repre...

One measure of the resilience of any dynamical system is the speed of return to equilibrium following perturbation. In electrical power distribution systems this may be approximated by the duration of unscheduled outages due to failure of the distribution system (i.e., excluding outages due to failure of the generation or transmission systems). We hypothesize that the resilience of power distri...

Since the mid-1980s, power sector liberalization has been embraced at different levels in the east Asian countries of China, Japan, South Korea and Taiwan. The dominant rationale underlying power liberalization has been a quest for efficiency improvements, to be achieved by substituting private market activity for public regulations and by opening a country’s electricity system to the global ec...

Absrracf This paper develops a coarse-grain parallel genetic algorithm for solving a service restoration problem in electric power distribution systems. Power utility performs service restoration in order to restore out-ofservice areas at fault. Developing effective service restoration procedure is a cost-effective approach to improve service reliability and to enhance customer satisfaction. Th...

In Digital Terrestrial/Television Multimedia Broadcasting (DTMB) Multicarrier (MC) mode system, Tail Cancellation and Cyclic Restoration (TCCR) is needed for Inter Symbol Interference (ISI) cancelling. In this paper, Threshold method combinated with averaging method and Power profile width detection method are proposed as new channel estimation in order to improve the performance of TCCR.

Received Jul 15, 2016 Revised Mar 13, 2017 Accepted Mar 27, 2017 Interline Dynamic Voltage Restorer (IDVR) comprises of several Dynamic Voltage Restorers (DVRs) connected to different distribution feeders in the power system sharing common energy storage. One of the DVR provides for voltage sag compensation appearing in that feeder, while the other DVRs restore the energy in the common dc-link ...
