Hybrid power supply system (HPSS) consists of Wind and Solar sources of electrical power with various operating times during various seasons and with Power storage system. Hybrid power system deployment is expected in places outside the normal distribution network. For the future research and improvement it is necessary to know in detail the power flow from various sources to the load or to storage batteries depending on various seasons. We are concern with reliability and optimization problem associated with HPSS. And several models of various techniques have been used to solve these problems. Several approaches, like multi-agent system, Supervisory model predictive control method, Unit sizing optimization; Maximum Power Point Tracking techniques and Dynamic modeling method are utilized to find out the optimal solution of non-linear problem. More recently, the computing techniques have received more attention and were used in a number of successful and practical applications. The aim of this work is to find out the advantages of application of the evolutionary computing techniques in particular to the reliability and optimization problem by analysis and comparison of various control strategy.

The global electrical energy consumption is steadily increasing and the installed classical high power stationeries cannot fulfill the demand on the other hand, continuous decrement of fossil fuels make incentives to invest alternative energy sources like wind power. Generally Squirrel Cage induction generator (SCIG), Doubly Fed Induction Generator (DFIG) and Permanent Magnet Synchronous generator (PMSG) are used in the wind power generating systems. Individual power coefficient is calculated for different tip speed ratio at fixed rotor speed for the above mentioned generators. A comparative efficiency performance has also been carried out in this paper and the most efficient turbine generator is found.

This paper uses the neural network theory to study the transient stability. The MATLAB simulink model of an alternator is considered to be connected to an infinite bus. The transient stability of this alternator is studied after a phase fault. The relative rotor angle is taken as the measuring parameter. A neural network based approach is applied to study the transient stability of the same system. This approach gives expected results.

This paper presents a CFD based 3-D numerical simulation of steady turbulent flow in the passage of a Francis turbine. The performance parameters under different operating conditions have been analyzed using available CFX code. The five different operating conditions from part load to over load of a Francis turbine are investigated and results are presented in the form of efficiency and head loss. It has been observed that head losses are minimum and efficiency is maximum at rated discharge and rated head. An attempt has been made to compare the computed results with the available model testing results. The numerical results are found to be in good agreement with the model testing results.

At the end of the solar module manufacturing process, an I-V measurement is performed under different illumination of each individual solar module to determine its current Imp and voltage Vmp at the maximum power point and the ISC and VOC points, where the power will be zero and the maximum value of power will occur between the two. The Fill Factor (FF) is essentially a measure of quality of the solar sell. When calculated the performance of the solar cell from I-V Characteristics using the conventional method, it was found that noise caused the I-V curves to zigzag slightly near the VOC and to zigzag widely near the `knee' of the curve. Defining the exact value of solar Module's parameters is called Module's Characterization. So in this paper the authors are tried to minimized the noise of I-V curve to get the highest power output using Automatic electronic load regulator and also find out a real value of ISC and VOC points from the I-V curve plotting using ATMEGA Microcontroller.

There is rapid growth in demand for air conditioning due to rising population and economic development. This technology should diversify and utilize alternative source of energy like solar energy for sustainable development. Liquid desiccant based air conditioning system (LDAC) is adaptable to solar thermal energy and has advantages like high density energy storage and low regeneration temperature. Regenerator in LDAC system removes moisture from LD absorbed in air dehumidifier. Various regenerators in literature like air scavenging regenerators and collector cum regenerator are discussed. These regenerators are compared and their pros and cons are given. The paper presents the topic in digestible form and provides a perspective to a professional in the field or a person who would like to start doing research in the field.

This paper presents on the continuous conduction mode (CCM) of operations of a flyback SMPS and stability analysis based on inclusive study and operating dogma. The modeling of the SMPS enlightens the stability with the power components and feedback loop. It is worked out by unbreakable poles and zeros of the transfer function of the SMPS, since the coupled inductor in the CCM is palpably a current source and the dominating pole is just the broken by the output capacitor and load resistor. This prediction predicts the upper limit of phase shift that is about 90 degrees of the closed loop stable operation.
