This paper presents optimal placement and estimation of distributed generation (DG) capacity using Particle Swarm Optimization (PSO) approach in the radial distribution systems to reduce the real power losses and to gain voltage profile improvement. Furthermore, the proposed method focuses on the installation of the DGs and takes more number of significant parameters into account compare to the...

Received May 23, 2015 Revised July 13, 2015 Accepted August 2, 2015 A new distributed generation placement method based on biogeographybased optimization (BBO) is investigated in this paper. A significant novelty of this study lies in considering fuzzy load uncertainty. For this purpose a fuzzy backwardforward sweep load flow is proposed. The main objectives of this study is minimizing power lo...

The active and reactive power flow in distribution networks can be effectively controlled by optimally placing Shunt Capacitors (SCs) and Distributed Generators (DGs). This paper presents improved versions of three evolutionary or swarm-based search algorithms, namely, Improved Genetic Algorithm (IGA), Improved Particle Swarm Optimization (IPSO) and Improved Cat Swarm Optimization (ICSO) to eff...

Transmission network congestion is an important issue in deregulated power systems, whenever the physical or operational constraints in a transmission network become active, the system is said to be in a state of congestion. Congestion management (CM) is a mechanism to prioritize the transactions and commit to such a schedule that will not overload the network. This paper presents relieving tra...

Modern distribution systems and microgrids must deal with high levels of uncertainty in their planning operation. These uncertainties are mainly due to variations loads distributed generation (DG) introduced by new technologies. This scenario brings challenges planners system operators that need tools perform more assertive analyses the grid state. paper presents an optimization methodology cap...

Distribution network is said to be the most visual part of electric production and observed by utilities for investment, maintenance operation. The system have been operated under stressed conditions due limited structure increasing day requirement power consumption, which a significant economic social impact on system. Due high resistance impendence ratio, large amount loss occur in network. T...

Embryo implantation requires a healthy embryo and a receptive endometrium (inner lining of the uterus); endometrial receptivity acquisition involves considerable epithelial surface remodeling. Dystroglycan (DG), a large cell surface glycoprotein, consists of α- and β-subunits; β-DG anchors within the plasma membrane whereas α-DG attaches extracellularly to β-DG. The glycosylated central α-DG me...
