Due to the scarcity of potable water in some places and inability of available natural sources to fill the growing need for supplies of safe drinking water in addition to the high cost of energy used in saline water desalination. Pollution of fresh water resources by industrial wastes has heightened the problem. Solar energy is one promising solution to meet these ever-increasing demand clean and eco-friendly techniques should be used like solar distillation. This study is done to find the effect of PCM on solar distillation in a double slope solar still. The principle of pure water production from saline water using different designs of a solar water distillation technique is the same. A phase change material is a substance with high heat of fusion which, on melting and solidification is capable of storing and releasing a large amount of energy. In a double slope solar still, solar distillation was performed and the distillate output collected was recorded without using PCM. Some modifications were made to the solar still. Solar distillation was again performed in the solar still with different PCM. The amount of the distillate collected changes with many factors. The selection of PCM is an important step in the project. There are various things to consider before choosing a PCM. The theoretical model of the solar still system is developed. Through the various experiments performed on the solar still, various analysis were shown.

The increasing energy demands around the globe and depleting conventional energy sources has compelled us to think of alternate sources of energy. The energy available from sun in the form solar radiation is of paramount importance in context of supplying the energy needs. The utilization of solar energy solely depends on the obtainable solar radiation flux at a particular geographical location. In this study, a novel attempt of predicting solar radiation at Amravati, Maharashtra, India (20.9374oN, 77.7796oE) has been made using different empirical models based on Angstrom-Prescott model, considering sunshine hour as prime parameter using MATLAB tool. Several statistical tests are used as basis of comparison such as the mean bias error (MBE), the mean percentage error (MPE), the root mean square error (RMSE), correlation coefficient (r). Based on the statistical results, the best model for considered site can be ascertained and used for predicting solar power plant capacity for Amravati. Due to absence of meteorological data at the considered site, this work will thus prove to be beneficial in estimating the solar radiation at Amravati and also at various sites having similar climatic conditions where measured solar radiation data is absent.

In this paper, the power dispatch problem of Distributed Generators (DGs) for optimal operation of microgrid has been considered. The islanded microgrid is further sectionalized into several areas which can be operated in autonomous operation for improving the system reliability especially at the time of separating faulty region. These areas will be operated individually or combining with other areas, or all are functioning at a time assuming that power generation in each area is able to feed its demand. The objectives considered to minimize in this paper are operating cost of DGs, system losses and cost & loss simultaneously. While scheduling the microgrid, dispatchable DGs like Diesel generators are used. GA is used in this paper for solving the stated optimization problem. The feasibility of the proposed technique is verified with the modified 33 bus distribution network and results are presented.

Distribution network has high power losses and poor voltage regulation as compared with transmission system due to high admittance ratio. Reconfiguration is one of the methods used in distribution system to reduce the power losses. Distribution networks are primarily designed in meshed structure, under normal operating conditions they are operated in radial configuration. Two types of switches viz., sectionalizing and tie line switches are normally used in distribution system. The operational performance of distribution system can be improved by changing the functional links between the switches or branches. Service restoration, improvement in voltage profile, load balancing and reduction in power loss are some of major advantages produced by reconfiguration. Since many switching combinations are possible, the optimal switching configuration of a power distribution network is a difficult non linear combinatorial optimization problem. In this paper, an Adaptive Quantum inspired Evolutionary Algorithm (AQiEA) approach is used to determine the optimal switching configuration of a power distribution network. Voltage dependent load models viz., constant current load, constant impedance and constant power load are used to reduce the power losses with reconfiguration. The main criterion addressed in this paper is minimizing the active power loss with network reconfiguration for different load models. A class of mix load model is also considered. Comparative study is performed on IEEE 33 bus system which demonstrates the performance, accuracy and effectiveness of the proposed algorithm.

Technology in almost every field is emerging & vanishing with the each passing day. Talking about the increasing burden on our roads and the issues of traffic congestion, the road network is demanding for a concrete and smart system which can work smartly to reduce the clearance time of vehicles as well as monitoring the flow of vehicles. This technology can also help indirectly in lowering the consumption of fuel and the lesser impact on environment. Monitoring and then controlling the vehicles in an automated and reliable manner as per the congestion at that time is the basic principle we have adopted for any further development. This research paper is a small contribution from our side into this dynamic field and we hope that it may help in the future in any sense to cope up with the existing and upcoming challenges ahead.

Early detection of fire is the key to save huge losses in terms of environment, property and lives. Wireless Sensor Networks (WSN) can help in early detection of fires and condition monitoring of such areas. In this paper a short-range communication network has been developed which can be used for sending and receiving data between different Zigbee (XBee) Radio Frequency (RF) modules using XCTU software from Digi. Different sensors for measuring parameters like temperature, humidity, smoke and flame are placed and the data is transferred using anXBee network. The developed wireless sensor network keeps track of the above-mentioned parameters. The measured parameters are transmitted up to a distance of 100m. An alarm has been set so that corrective action can be taken ata preventive stage. The paper provides experimental results of the placed sensors in real time on an XCTU terminal port. Numerical results along with future scope of this work are given in the subsequent sections.
