Recently, the integration of wind farms has increased to high penetration levels. Mathematical modeling of wind generator is concerned in this paper. To discuss the steady state condition of power systems with wind farms, the stall regulated fixed speed wind generator (SR-FSWG) power flow model is considered. The load flow equations are solved using Particle Swarm Optimization technique including...

One such material is Carbon Fibre Reinforced Carbon (CFRC) composite material, which is used mostly in the fabrication of advanced structures like space shuttles, battle field tanks, missiles etc. Generally...
A designing pattern provides generic idea of a solution to solve a recurring problem with variety of goals and constraints. In object oriented program, design patterns are recognized by source code. This paper provides overall idea about design patterns, different types of analysis and their comparison details with detection techniques of pattern. It also explains how it is related with non functional...
In this paper the static voltage stability index has been identified by minimum singular value of the power flow jacobian matrix. The system security in power system models by the scalar magnitude of a voltage stability index may be a very difficult task. When we are taking account of reactive power generation limits it is very difficult to predict stability index at voltage collapse points. Here...
The implementation issues associated with the control algorithm for a STATCOM in a series compensated wind generation system for mitigating SSR and damping power system oscillations. In order to damp out system oscillation and sub synchronous resonance we are providing STATCOM controller. The modeled SSR is adopted with integrating aggregated doubly fed induction generator-based wind turbine to perform...
The main concept of this paper is to identify and classify the various types of shunt and line faults in transmission line. The faults may be an insulation failure, lightning or accidental faulty operation. In a transmission line protection important factor is identifying a fault because if any error occurs in finding fault may leads to disoperation of the protection system. So either a disturbances...
Microgrid have been accepted concept widely for the better interconnection of DGs. Corresponding to the conventional power system ac microgrid have been proposed, particularly increasing the use of renewable enery sources generate dc power which need a dc link for the grid connection and as a result of increasing modern dc loads. Dc microgrid have been recently emerged for their benifits in terms...
Due to the development in the field of Power Electonics many FACTS devices such as SVC, STATCOM, TCSC, UPSC are introduced in transmission lines. These devices are used to improve the system voltage profile, stability, Powerflow etc. Distance Relays are unique devices used to protect the transmission line from various faults. The reach of the relay is independent of the type of fault. Distance Relays...
This paper describes a successful adaptation of particle swarm optimization (PSO) algorithm to solve the economic dispatch (ED) problem with valve point effects in power system. In this paper, PSO method is used to describe the equality and inequality constraints in the Economic Dispatch problems. The proposed algorithm has been tested on 3 unit system with quadratic cost functions. Numerical example...
In this modern world due to the increased number of different types of loads in the power system the voltage profile and the power quality is being affected. So one of the cheapest and widely used method to improve the voltage profile is to install capacitor banks. They are erected in the distribution substation and are connected to a bus where more number of loads are connected. Nowadays various...
This paper focuses on the design of single input single output fuzzy controller for a Power oscillation controller based SSSC for damping rotor oscillation in power system network. The oscillation due to disturbance cannot damp out only by SSSC, but with single input Fuzzy tuned Damping controller based SSSC can easily damp out the oscillation. Here the proposed system has been implemented in the...
The aim of this paper is to design a power electronics converter interfacing Utility Grid and AC Microgrid to reduce frequency variation in a grid during frequent load variation in another grid. The utility grid is interfaced with the AC Microgrid using an interfacing converter. Interfacing Converter protects microgrid from utility grid and vice versa during frequent variation of load. It allows bidirectional...
In this paper, operation of IPFC is analysed in transmission line power flow control IPFC is used for controlling transmission line voltage, flow of power, decreasing power losses, and decreases the amplitude of an oscillation while transferring power. This paper deals with finding the location and optimal placement of interline power flow controller to maintain the voltage profile, active and reactive...
Java is generally considered as a slow language when it conies to High Performance Computing. Standard performance tests in a High Performance Computing scenario, against languages like C and FORTRAN yield that Java does perform below par while executing parallel computational logic. This can be owed to slower compilation time of complex logic on a standard JVM, overhead caused due to multithreading...
Computing requirements and Information technology infrastructure are growing exponentially in the present days. Computing has penetrated into all domains and henceforth consumes a major share of power. Technologies and hardware architectures focus on designing low power devices and power aware systems to gain effective power usage. One amongst the technology is NComputing virtualization for effective...
