Reckless consumption of electric power by the consumers is one of the main reasons of depletion of resources (coal, petroleum) and increasing tariff. To improve the current statistics of distribution and consumption the Smart grid brought out a scheme providing the consumer higher control over the power generation and distribution thus increasing the responsibility of the consumer making them more vigilant and providing for sustainable development. Smart Grid improvises the conventional grid on various levels which calls forth the requirement for sophisticated controls carried out in various levels namely, primary, secondary, and tertiary. This paper deals with the intelligence associated with the primary and secondary levels placed in regard with the consumer and micro-grid operation. The role of the consumer as well as micro-grid in intelligent demand management has been demonstrated in this paper through simulations in MatLab using fuzzy logic.

The power conversion is one of the major requirements in utilizing the Electricity generated from the Solar Energy. This paper involves the boosting of DC output of the solar panel by Super-Lift Luo Boost Converter. The converter employs the Super-Lift technique to obtain the boosted output voltage. The output voltage of the Super-Lift Luo Boost converter increases in geometric progression. The Super-Lift Luo converter enhances the voltage transfer gain in power series. Thus after DC/DC conversion, the boosted output voltage is fed to the inverter wherein it is converted into AC voltage. The inverter AC output voltage can now be used to drive the AC loads. An extensive simulation of Super-lift Luo Boost Converter is conducted on the basis of reference values in MATLAB/Simulink environment. In order to determine the converter parameters MATLAB program has been used.

Heat dissipation, recovery and accumulation is more and more becoming the limiting factor in the advancement of many energy systems. The conventional heat pipes such as copper grooved heat pipes and sintered particle heat pipes have played an important role in the heat dissipation in electronic equipment. Pulsating heat pipe (PHP) is a new type of efficient heat transfer device, which was introduced in the mid-1990s by Akachi. PHP can be used for cooling of electronics because of its potential for removing high heat flux. The capillary effect is indeed provided by the small dimension of the channel, and not by the presence of a wick structure. An experimental study was conducted to investigate heat transfer performance of a closed loop pulsating heat pipe with pure water and aqueous solution of butanol (self-rewetting fluid) under various filing ratios, inclination angles and heat inputs. Self-rewetting fluids have a property that the surface tension increase with increase in temperature. Butanol is added to pure water at 0.1 wt% and 0.5 wt% concentrations to make self-rewetting fluid. The PHP is made of copper tube with inner and outer diameters of 2.0 mm and 3.0 mm, respectively. It is observed that lower thermal resistance is obtained by using aqueous solution of butanol compared with pure water. Also aqueous solution of butanol shows improved performance up to horizontal orientation, when compared with pure water.

The purpose of this project is to design, fabricate and test the performance enhancement of a SWH with compound parabolic reflector (CPR). The advantage of this system is that there is no need of a sun tracker. Firstly, the experimental work is done by comparing the performance of two evacuated tube collectors, out of which one is equipped with a CPR at the bottom surface. Secondly, an ANSYS simulation is done to find the effect of thermal loss on the performance of the system. For almost all of the SWH which are commercially available, only the top portion of the evacuated pipe is used for absorbing the solar radiation. The shaded portion remains unused. A CPR uses a mirror in the shape of a compound parabola to reflect and concentrate sun radiations towards a receiver tube located at the focus line of the compound parabolic reflector. Thus the whole cylindrical surface of the evacuated pipe is made useful and the absorber surface absorbs the incoming radiations and transforms them into thermal energy. Thermal losses will occur mainly due to radiation and even though the system uses an evacuated tube collector, a small amount of loss occurs due to convection. Thus a thermal loss analysis around an evacuated tube collector is performed.

Gesture Controlled Robot is a robot that can be moved according to our hand movements. Accelerometer sensor is mounted on hand. The sensor mounted on your hand will judge the movement of hand in a particular direction. This project develops the hand movement monitoring system which feeds the data into the computer and gives the 3D visualization of accelerometer according to pitch, yaw and roll motions of accelerometer. In this project I used Adxl335 as the accelerometer and this project describes the controlling of servomotor(Futabas3003) according to motions of accelerometer and we can view the 3D visualization of accelerometer by interfacing Arduino (at mega 328p) with the processing software and MATLAB is used for graphical results of accelerometer motions.

Induction motors are the workhorse of industry, have good efficiency at rated load, but long duration usage of IM at partial load shows poor efficiency which leads to waste in energy and revenue as well. These motors are reliable, robust, high power/mass ratio and economic, hence replaced all other motors in the industry, so even minute increment in induction motor efficiency can have a major impact on consumption of electricity and saving of revenue, globally. This paper utilizes, a combination of two key concepts of efficiency optimization-loss model control (LMC) and search control (SC) for efficient operation of induction motors used in various industrial applications, in aforesaid load condition. At first, to estimate optimal Ids values for various load conditions, an optimal Ids expression in terms of machine parameters and load parameters, based on machine loss model in d-q frame along with classical optimization technique, is utilized. Secondly, an offline trained artificial neural network (ANN) controller is used to reproduce the optimal Ids values, in run-time load condition. This eliminates run-time computations and perturbation for optimal flux, as in conventional SC method. The (ANN) optimal controller is designed for optimal Ids as output, while providing load torque and speed information as inputs. The training is performed in MATLAB and good accuracy of the training model is seen. Dynamic and steady-state performances are compared for proposed optimal (optimal Ids) operations and conventional vector operations (constant Ids), with the help of a simulation model, developed in MATLAB. Excellent dynamic response in load transients as well as superior efficiency performance (1- 18%) at steady-state, for a wide range of speed and torque in simulation is attained. Assimilated with similar earlier work, the proposed methodology offers effortless implementation in real-time industrial facilities, ripple free operations, fast response and higher energy savings.

The objective of the study is to estimate the solar flux for a heliostat based central receiver system. Analytical and Monte Carlo ray tracing based numerical simulations have been performed to assess the solar flux on a fixed target. The simulations have been performed using a freeware Sol Trace released by NREL (National Renewable Energy Laboratory). A flat heliostat of (1×1 m2), which is located 10 m far from the base of a 15 m high tower, on which, (1.6×1.6 m2) target is considered for the study. Sketch up has been used for designing the model. NIT Warangal, India with a longitude 79.5 ° E and latitude 18 ° N is considered to predict the solar flux on the target on 1st April from 9 am to 5pm at the interval of one hour. Result obtained from analytical and numerical methods are compared in terms of solar flux on the target. It is observed that maximum variation between the two methods is within ±5%. The study could reveal that the field losses play an important role in the heliostat based central receiver system.

This paper presents the coordinated control of HVDC link with optimal sliding mode control and HVDC link with H-infinity controller has been proposed to solve load frequency control of multi area power system in open market environment. The performance of proposed coordinated control strategies such as HVDC-OSMC, HVDC-H-infinity has been demonstrated on two area deregulated thermal power system under one possible contact scenario.
