This paper deals with Voltage and frequency controller for wind generating system with unbalanced linear loads. The proposed system is modelled and simulated in MATLAB using simulink .The controller that controls both voltage and frequency of an asynchronous generator along with its improvement of power quality. The proposed controller has bidirectional active and reactive power flow capability...

Prefix search is a fundamental operation in information retrieval, but it is difficult to implement in a peer-to-peer (P2P) network. Existing techniques for prefix search suffer from several problems: increased storage/index costs, unbalanced load, fault tolerance, hot spot, and lack of some ranking mechanism. In this paper, we present KISS (Keytokenbased Index and Search Scheme), a simple and ...

This paper investigates parallelization strategies for solving power flow problems in both transmission and unbalanced, three-phase distribution systems by developing a scalable power flow solver, ExaGridPF, which is compatible with existing high-performance computing platforms. NewtonRaphson (NR) and Newton-Krylov (NK) algorithms have been implemented to verify the performance improvement over...

In this paper, using particle swarm optimization (PSO) based method is developed to determine the optimal allocation of distributed generators (DGS) on a multi phased unbalanced distribution network. PSO algorithm has been programmed in MATLAB using open source software called OpenDSS in a cosimulation environment to solve the unbalanced three-phase optimal power flow (TOPF) and to find the opt...

This paper presents a novel approach to determinethe power system stability using resistive superconducting faultcurrent limiter (SFCL) of an electric power grid (EPG). Inaddition, the electric railwaysystem has rapidly changing loadcharacteristics in time. An unbalance is generated owing to therapidly changing large single-phase loads. Subsequently, the unbalanced load causes an unbalanced tra...

In large-scale distributed-computing environments, there are a number of inherent time-delay factors that can seriously alter the expected performance of load-balancing (or scheduling) policies that do not account for such delays. This situation arises, for example, in systems for which each computational element (CE) is connected by means of a shared broadband communication medium. The delays,...

Abstract—There are a variety of reference current identification methods, for the shunt active power filter (SAPF), such as the instantaneous active and reactive power, the instantaneous active and reactive current and the synchronous detection method are evaluated and compared under ideal, non sinusoidal and unbalanced voltage conditions. The SAPF performances, for the investigated identificat...

This research work presents the comparison analysis of Shunt Active Filter (SAF) with Parallel Hybrid Active Filter (PHAF). The performances of SAF and PHAF have been analyzed with PI controllers based on Synchronous Reference Frame theory. In each case, simulation is carried out for three phase unbalanced non liner load conditions. The advantages of the designed system and the proposed current...

This paper deals with the performance analysis of static compensator (STATCOM) based voltage regulator for self excited induction generators (SEIGs) supplying balanced/unbalanced and linear/non linear loads. A threephase insulated gate bipolar transistor (IGBT) based current controlled voltage source inverter (CC-VSI) known as STATCOM is used for harmonic elimination. It also provides the requi...

in distribution systems, in order to diminish power losses and keep voltage profiles within acceptable limits, network reconfiguration and capacitor placement are commonly used. in this paper, the hybrid shuffled frog leaping algorithm (hsfla) is used to optimize balanced and unbalanced radial distribution systems by means of a network reconfiguration and capacitor placement. high accuracy and ...
