In the electrical distribution network, reactive power compensation aims at guarantying an efficient delivery of active power to loads, releasing system capacity, reducing system losses, and improving system power factor and bus voltage profile. The achievement of these aims depends on the sizing and location of shunt capacitors (sources of reactive power). Operational, economical and quality o...

This paper presents an effective approach to simultaneous solution of capacitor setting and feeder reconfiguration for power-energy loss reduction and voltage profile enhancement in radial distribution systems. An optimization method using a Genetic Algorithm is proposed to determine the optimal selection size, location, type and number of fixed or switched capacitors as well as the open/closed...

The problem of optimal planning of multiple sources of distributed generation (DG) in distribution networks is treated in this paper using an improved Ant Colony Optimization algorithm (ACO). This objective of this problem is to determine the DG optimal size and location that in order to minimize the network real power losses. Considering the multiple sources of DG, both size and location are s...

In this study, the radial distribution and gravimetric storage capacities of hydrogen on coronene (C24H12) and its Si substituted forms, C24H12, C24-nSinH12 (n= 4-24), have been investigated at 298 K and 0.1 MPa (standard situation) using (N,V,T) Monte Carlo simulation by Lennard-Jones (LJ) 12-6 potential. The results show that the increase of number of silicon substitution doesn’t have any eff...

Distribution load flow (DLF) calculation is one of the most important tools in distribution networks. DLF tools must be able to perform fast calculations in real-time studies at the presence of distributed generators (DGs) in a smart grid environment even in conditions of change in the network topology. In this paper, a new method for DLF in radial active distribution networks is proposed. The ...
