The electrical energy consumption is rising and there is a steady increase in the demand of power generation. So, we can go to non-conventional energy sources like solar, tidal, wind and etc. In that wind generating system is rapidly growing one. The wind speed is not constant at all times they can using variable speed wind turbine (VSWT) or (DFIG). The DFIG wind turbine is recently most used turbine...
This paper deals with application of automatic generation control (AGC) to deregulated power system and makes a maiden attempt to provide a new practical AGC model to cater to the needs of a modern restructured hydrothermal power system. Several DISCO Participation Matrix (DPM) and Area Participation Factor (APF) have been tried out and dynamic responses for frequency, tie flow and generations are...
This paper deals with load frequency control study of high, medium and low head single area hydro power system. The gains of proportional-integral-derivative (PID) controller have been optimized using Particle Swarm Optimization with integral squared error (ISE) and integral time absolute error (ITAE) performance index as fitness functions. Simulations are carried out for the same using MATLAB/SIMULINK...
Due to the increasing interest on renewable sources in recent times, the studies on integration of distributed generation to the power grid have rapidly increased. In order to minimize line losses of power systems, it is crucially important to define the location of local generation to be placed. Proper location of DGs in power systems is important for obtaining their maximum potential benefits. This...
A single inductor three output converter is proposed which operates in discontinuous mode (DCM). The three outputs are multiplexed and are fed power one after the other from the same source. Due to DCM operation, there is no interference between the outputs. During the period when an output is not connected to the source, filter capacitors provide power to the load. The devices are turned off at zero...
Effective utilization of computing resources and prediction of future resource capabilities are needed to achieve high performance computing in grid Environment. To ensure this, effective and flexible forecasting and prediction method needed to use time-shared resources for large applications which impact greater importance for scheduling. Predicting the available performance on each resource is basic...
Accurate load forecasting play a key role in economical use of energy and real time security analysis of system. Artificial Neural Network (ANN) model have been extensively implemented to produce accurate results for short-term load forecasting with time lead ranging from an hour to a week. In this paper a practical case of the small load area of a town getting supplied by 19 distribution feeders...
This paper presents the systematic procedure of the modeling and simulation of a Dynamic Voltage Restorer (DVR) for power quality problems, voltage sag and swell based on Sinusoidal Pulse Width Modulation (SPWM) technique. Power quality is an occurrence manifested as a nonstandard voltage, current or frequency that results in a failure of end use equipments. The major problems dealt here is the voltage...
Mobile ad-hoc network is a wireless infrastructure network where there is no central co-ordination among the nodes. The nodes try to communicate with each other without any fixed networking infrastructure, thus the ad-hoc network is self adaptive. This paper presents a scheme to balance the load with energy efficiency considering both congestion and the nodes energy usage. A threshold value is used...
The application server handles dynamic and sensitive Web contents that need protection from eavesdropping, tampering, and forgery. Although the Secure Sockets Layer (SSL) is the most popular protocol to provide a secure channel between a client and a cluster-based network server, its high overhead degrades the server performance considerably and, thus, affects the server scalability. Therefore, improving...
