Network reconfiguration (NR) is one of the most effective methods to reduce line power loss in distribution system, which causes higher losses than other parts system. This paper proposes a modified symbiotic organisms search (MSOS) algorithm solve NR problem. For purpose enhancing effectiveness MSOS, mutualism and parasitism strategies original (SOS) have been create better new solutions. In s...

In the event of a fault isolation process, all loads located downstream from faulted point become out service, and as consequence, power interruption affects greater portion radial distribution system. This paper proposes an optimal Service Restoration (SR) method that entails changing network topology configuration via tie-switch section switch combinations. However, when is performed, it resu...

To estimate the Cation Exchange Capacity (CEC), indirect manner used of Pedotransfer Functions (PTFs). CEC is one of the important soil fertility factors, and not measured directly because it is costly and time consuming. Thus, used from regression equations between easily and non-easily soil properties. The purpose of this research, is develop the PTFs for CEC, with use of easily available soi...

This paper presents an efficient algorithm for network reconfiguration associated with DG allocation to minimize real power losses in radial distribution networks. A modified Binary Particle Swarm Optimization algorithm, called Selective Particle Swarm Optimization algorithm (SPSO), is used to solve network reconfiguration problem. Allocation of DG units has been done by sensitivity analysis. A...

Electrical distribution network reconfiguration is a complex combinatorial optimization process aimed at finding a radial operating structure that minimizes the system power loss or/and maximizes the system reliability while satisfying operating constraints. In this paper, a distribution network reconfiguration method is presented for both the indices of power loss reduction and reliability imp...

Optimal placement of scattered generator sources in the main and secondary feeders of radial grid reduces energy losses, releases the capacity of existing feeders and improves the existing voltage profile. In this project determine the location and suitable for the production of production resources S cattered in radial feeders of unbalanced distribution networks, a new formulation solution is ...

The structure of a distribution network has great effects on economy, power supply reliability and investment of a power system. To obtain an optimal topology from possible topologies, we need to solve an optimisation problem which aims to find a radial structure satisfying operating constraints. As a basis of solving this optimisation problem, the encoding scheme, is to represent the candidate...

Now in an active noise control system the adaptive controller is based on the linear theory; however the research shows that the characteristics of practical noises are more nonlinear. In order to trace the timing-varying noise, an active noise control model based on the radial basis function neural network is proposed. Experimental study shows that as a local and whole conjunction neural netwo...

The radial distribution of dose about the path of a heavy ion, principally from delta rays, is one of the central contributions of atomic physics to the systematization of high LET radiation effects in condensed matter, whether the detection arises in chemical, physical, or biological systems. In addition to the radial distribution of dose, we require knowledge of the response of the system to ...
