A static synchronous compensator (STATCOM) is generally used to regulate voltage and improve transient stability in transmission and distribution networks. This is achieved by controlling reactive power exchange between STATCOM and the grid. Unbalanced sags are the most common type of voltage sags in distribution networks. A static synchronous compensator (STATCOM) is generally used to maintain...

In this paper, power distribution planning (PDP) considering distributed generators (DGs) is investigated as a dynamic multi-objective optimization problem. Moreover, Monte Carlo simulation (MCS) is applied to handle the uncertainty in electricity price and load demand. In the proposed model, investment and operation costs, losses and purchased power from the main grid are incorporated in the f...

Grid computing involves the coordination of multiple distributed processes such that they function as one system. Computational Grids are used to achieve this. Grid computing operates through the use of remote machines accepting executable code, which they process. Grid computing defines far more than the organisation and architecture of computational networks. How Grid is used, the policies un...

We explore the problem of secret-key distribution in unidirectional channels, those in which a sender transmits information blindly to a receiver. We consider two approaches: (1) Key sharing across space, i.e., across simultaneously emitted values that may follow different data paths and (2) Key sharing across time, i.e., in temporally staggered emissions. Our constructions are of general inter...

South Africa’s Government policy embraces the inclusion of distributed energy resources (DER), namely: renewable energy generation, embedded generation (EG) or distributed generation (DG) in the future national generation mix. The renewable energy program incorporates wind power, concentrated solar power (CSP), solar photo-voltaic (PV), landfill, and mini/micro hydro, and envisages a total of 1...

Balanced cross-sections across the Zagros fold–thrust belt in Iran are used to analyze the geometry of deformation within the sedimentary cover rocks, and to test the hypothesis of basement involved thrusting throughout the fold–thrust belt. Although the Zagros deformation front is a relatively rectilinear feature, the sinuous map-view morphology of the mountain front is a result of a 6 km stru...

In this paper a new genetic algorithm called the Breeder Genetic Al gorithm BGA is introduced The BGA is based on arti cial selection similar to that used by human breeders A predictive model for the BGA is presented which is derived from quantitative genetics The model is used to predict the behavior of the BGA for simple test functions Di erent mutation schemes are compared by computing the e...

Soil nitrate-nitrogen (NO3-N) data arranged on a three-dimensional grid were analyzed to compare tillage effect on the spatial distribution of residual NO3-N in the soil profile of agricultural plots drained by subsurface tiles. A three-dimensional median-based resistant (to outlier(s)) approach was developed to polish the spatially located data on soil NO3-N affected by directional trends (non...

We consider the effect of doping on the magnetic order in quasi one-dimensional (1D) antiferromagnets. First the detailed magnetic response of finite spin-1/2 chains in the presence of a staggered field is determined, which by itself shows an interesting crossover as function of length and field strength. We can then understand the ordering by including an effective coupling between the chains,...

Abstract: Since a smart distribution grid has a diversity of components and complicated topology; it is very hard to achieve fault early warning for each part. A fault early warning model for smart distribution grid combining a back propagation (BP) neural network with a gene sequence alignment algorithm is proposed. Firstly; the operational state of smart distribution grid is divided into four...
