This research paper includes the concept of distributed generation of electrical energy from various types of renewable energy sources. The distributed energy resources (DER) system is located near to the load which improves the security of supply. Due to this the transmission line costs and losses are also reduced. This will result in efficient utilisation of electrical energy generated and ultimately improve the energy efficiency in the power system. As the DER system uses renewable energy sources, it also reduces the environmental impacts.

Amongst various transduction principles of pressure sensor, piezoresistive method provides high sensitivity and linear operation over a wide range of pressure. In this paper, piezorestive transduction mechanism is employed for design of a pressure sensor. The diaphragm of the proposed sensor is designed using n-type of Si with copper material used as a connecting arms for the p-type meander shaped piezoresistors placed on the surface of the diaphragm in a Wheatstone bridge configuration at the high strain region of the diaphragm. Meander shape piezoresistors of different length are simulated, in order to find out the best configuration for high sensitivity and linearity. The proposed design is analysed to study the deflection of the diaphragm and output voltage across the bridge. Results reveal that the 50 μm length of piezoresistors is found to have the best sensitivity.

The present scenario of drying applications has contributed the emerging trends in the field of science and technology. The conventional drying systems have good proven results but at higher energy cost. The alternative means of drying system is the application of solar energy, which yields better results at the very low cost of energy. There is a need to develop the solar systems to achieve the sustainable development in case of drying applications. The presented work reports on the behavioral characteristics of solar dehydrator and greenhouse dehydrator as compared to open drying of green grapes and chilies.

This paper presents a prototype implementation of a three-level Diode-Clamped Inverter (DCI) fed energy efficient IPMSM drive. A MOSFET based bridge inverter is chosen and the pulses are produced using Digital Signal Processor (DSP) TMS320f28335. Using the embedded coder tool box, the Simulink model is compiled and programmed with the software Code Composer Studio (CCS) which is a compiler and programmer. The pulses from the DSP are fed to the DCI Bridge with an Optocoupler isolation unit. The output of the inverter is fed to the Interior Permanent Magnet Synchronous Motor (IPMSM) drive for the analysis. Hardware implementation of the proposed work is carried out on IPMSM and the results were presented.

The high penetration of the Renewable Energy Sources (RES) can create stability, reliability and power quality problems in the main electrical grid due to their stochastic nature. Microgrids can be analysed as a solution capable of guaranteeing a controlled injection of energy generated by the renewable energy technologies. The use of storage system in a MG plays an essential role in order to ensure energy balance and in maintaining high power quality. Due to the technical limitations of the currently available storage systems, it is necessary to use more than one storage technology to satisfy the requirement of microgrid applications. In order to satisfy the above constraints, this paper proposes the association of a supercapacitor (SC) and a lithium ion battery in a Hybrid Energy Storage System (HESS). A novel control strategy is adopted for the control of the HESS. Hierarchical control is used for the control of the inverter in islanding and grid connected mode. Self synchronization control ensures smooth transition between islanded and grid connected modes. Simulation of the system is carried out in MATLAB/Simulink.

In this investigation an effort has been made to find the effect of water depth on distillate production and to establish thermodynamic relations among the operating parameters to study their effects on still performance. In this work water is heated in a water bath and the top cover is replaced with a glass to act as condensing surface. Water is fed into water bath, the gap between water surfaces and condensing surfaces is reduced gradually. The water temperature is varied from 40-70°C at different water level during the experiment. The amount of distillate production and temperature variation was measured at an interval of 15 minutes. Based on the experimental observation, it is found that a very close agreement between theoretical and experimental results is found. The Nusselt and Grashof numbers are calculated for various experimental conditions and values of constants (C and n) are obtained from regression analysis for individual depth of water.

This paper addresses the problem of solar photovoltaic water pumping during monsoon weather conditions for domestic and small scale agricultural purposes. Since solar radiation varies rapidly during monsoon conditions, a variable speed water pumping system could be a possible solution for this problem. For fixed head applications, the speed variation should be done in such a way that the maximum power should be extracted from solar panel without affecting the head of the water pumped. This paper proposes a variable speed water pumping system, using a Brushless DC (BLDC) motor which gives better efficiency compared to that of induction motor and also reduced maintenance requirements over brushed DC motors. Moreover, BLDC motors offer excellent speed-torque characteristics; high torque to size ratio, high starting torque, lower acoustic noise and electromagnetic interference, long operating life and simpler constructional feature which make them well suited for low power solar water pumping applications.
