We have developed a new algorithm, RBF-MREIT, for Magnetic Resonance Electrical Impedance Tomography (MREIT) by applying the radial basis function (RBF) network and Simplex method. RBF-MREIT uses only one component of the measured magnetic flux density to reconstruct the conductivity images, and provides a solution to the rotation problem in MREIT. The proposed algorithm is tested on a three-sp...

The distribution system acts as a conduit between the consumer and bulk power grid. Due to characteristics such high resistance/reactance ratio, networks cannot be solved using conventional methods, Gauss-Seidel Newton–Raphson. This research proposes method for calculation of flow in radial that considers their wide range resistance reactance values, PV generator characteristics, structure. An ...

Single phase line-broken (SPLB) fault is one kind of high impedance (HIF). When a SPLB occurs, there are four scenarios: with neither side conductors grounded (SPLB-NSCG), source conductor only (SPLB-SSCG), load (SPLB-LSCG), both (SPLB-BSCG). Traditional HIF detection methods using current or voltage characteristics have low sensitivity to fault. In this paper, analysed firstly in the cases fir...

Distribution system represents a crucial portion of power as it is the connection between bulk transmission network and customers connected at load point. networks are increasing in size spread too far. Low reactance to resistance ratio large leads higher losses lines low node voltage customer end. High reduce efficiency affect economy. Therefore, this paper an algorithm for reconfiguration dis...

Small generation units connected to distribution systems can improve end-user power quality; e.g. by providing voltage support. However, the presence of distributed generation (DG) changes the radial nature of distribution systems and affects the performance of the protection system. DG can also affect duringand post-fault voltages; in addition, voltage sags are highly influenced by the type of...

Simultaneous radial distribution network reconfiguration (RDNR) and shunt capacitor allocation (SCA) is one of the compensation techniques that are used for getting an improved structure with reduced real power loss enhanced voltage stability. This study presents a novel adaptive particle swarm optimisation (APSO) technique simultaneous RDNR SCA, which complex nonlinear problem. Unlike conventi...

This paper provides a probabilistic method to assess the impact of wind turbines (WTs) integration into distribution networks within a market environment. Combined Monte Carlo simulation (MCS) technique and market-based optimal power flow (OPF) are used to maximize the social welfare by integrating demand side management (DSM) scheme considering different combinations of wind generation and loa...

Distributed Generation (DG) has been envisaged to play an escalating role in electrical power system in near future. However, the benefits of DGs cannot be explored if they are not optimally placed. The efficiency of the distribution system is increased units. As the employment of the DG comes with the enhancement of the distribution feeders. Network (RBFNN) based strategy to penetrate the Radi...
