The paper presents voltage stability analysis of radial distribution networks under critical loading conditions without and with shunt capacitor. A new voltage stability index is proposed for identifying the node, which is most sensitive to voltage collapse. The effectiveness of the proposed method without and with considering shunt capacitor has been successfully tested on a 12.66 kV radial distribution...
The paper presents voltage stability analysis of radial distribution networks under critical loading conditions without and with distributed generator (DG). A new voltage stability index is proposed for identifying the node, which is most sensitive to voltage collapse. The effectiveness of the proposed method without and with considering DG has been successfully tested on a 12.66 kV radial distribution...
This paper presents status of all branches of radial distribution networks in chronological order using distributed generation at optimal position by considering the concept of reactive loading index technique. Although under different situations for all the branches the identified weakest branch remains same up to some specified conditions but the corresponding loading at different branches in chronological...
The paper presents voltage stability analysis of radial distribution networks under critical loading conditions without and with distributed generator (DG) for composite loads. A new voltage stability index is proposed for identifying the node, which is most sensitive to voltage collapse. The effectiveness of the proposed method without and with considering DG for loads of composite types has been...
The worsening misalignment between energy demand and supply with major consequences on energy prices, threat of disruptive climate change and erosion of energy security have given momentum towards utilization of distributed generation (DG) technologies. However, proper choice of DG technology and its location and size in the distribution network have become a very challenging issue. This paper analyzes...
Renewable distributed generation (DG) has become one of the key drivers of fast changing energy scenario around the world. A clear strategy is ardently essential to accelerate growth of grid interactive renewable DGs. This paper proposes a constrained multi objective particle swarm optimization based planning of renewable DGs for distribution network. The proposed method tries to find the best trade-off...
A method of registration of progressively transmitted MR images with lesions are proposed. The MR image is segmented using Entropy Maximization together with Hybrid Particle Swarm Optimization that incorporates Wavelet Mutation operation. The segmented MR image is progressively received at the receiver's end. Registration is used to ensure correct transmission and fusion of segmented MR image with...
Penetration of distributed generation (DG) units in distribution network has increased rapidly stimulated by reduced network power loss, improved bus voltage profile, and better power quality. Appropriate size and allocation of DG units play a significant role to get beneficial effects. The objective of this study is to demonstrate a simple and fast technique to determine appropriate location and...
A Hybrid Particle Swarm Optimization algorithm that incorporates a Wavelet theory based mutation operation is used for segmentation of Magnetic Resonance Images. We use Entropy maximization using Hybrid Particle Swarm algorithm with Wavelet based mutation operation to get the region of interest of the Magnetic Resonance Image. It applies the Multi-resolution Wavelet theory to enhance the Particle...
