An innovative overload protection scheme is proposed to enhance the reliability of classical overload relays. The protection logic includes an accurate thermal model of bare overhead conductors, which allows to explicitly estimate the line temperature using the electrical current and weather conditions. In particular, the climatic variables are suitably represented by stochastic models that inc...

The imbalance of phase loads is a natural negative property low-voltage three-phase four-wire network due to uneven connection the phases and difference in individual consumer demand for electricity. nodes leads decrease quality electricity, overestimated technical losses current overloads one power lines. In paper, balancing performed using heuristic algorithm based on average hourly readings ...

Chee Siang Ang We conducted a qualitative study to explore the effect of cognitive overloads in Maple Story, a typical Massively Multiplayer Role Playing Game (MMORPG). Our results reveal that several types of cognitive overloads emerge during the game playing. While some of these overloads pose serious problems, even to expert players, some are actually desirable in order to make the game chal...

The increasing number of renewable energy sources (RESs) connected to power grids contributes the emergence not only balancing problems but also technical ones, such as overloading lines. If with a high generation level are planned be in area under consideration, then large significant overloads should expected, especially during contingency analysis. As rule, high-voltage networks have mesh to...

In this article, we present two formulations and their unification for the Mixed-Model Sequencing Problem with Workload Minimisation (MMSP-W) for production lines with serial workstations and parallel homogeneous processors. The models were executed in Solver CPLEX, with reference instances and with a case study of Nissan’s Powertrain plant in Barcelona. Different situations were analysed to ev...

by Thidapat Chantem This dissertation presents several design techniques for resource-constrained, dependable embedded real-time systems, which can be found everywhere from cellular phones to automotive electronic systems to medical devices. Specifically, three important challenges in embedded real-time system design are identified and addressed: temporal overloads, energy concerns, and tempera...

The paper proposes a security-constrained optimal power flow algorithm (SC-OPF) which allows the post-contingency control of High Voltage Direct Current lines, based on the Voltage Source technology (VSC-HVDC). The presented algorithm integrates corrective actions of HVDC lines in a single optimization problem, without the need to solve a detailed power flow or OPF for each contingency. The app...

Nowadays, high importance is given to low energy devices (such as refrigerators, deep-freezers, washing machines, pumps, etc.) that are able to produce reactive power in power lines which can be optimized (reduced). Reactive power is the main component which overloads power lines and brings excessive thermal stress to conductors. If the reactive power is optimized, it can significantly lower th...
