In this modern era power generation seems to be a very demanding factor. New models and methods have been proposed to derive from various natural and man made resources. In such instances this paper gives a detailed report on the power generation from micro turbines. To enlist the microturbines as a prime source of energy utility restructuring, technology evolution, public environmental policy and expanding power demand are some of the most notable factors. Gas turbines plays a very important role in electric power generation. Especially they are used in the Combined cycle process power Plants. The parameters of Rowen's model 265-MW single shaft heavy duty gas turbines which are used in dynamic studies are estimated in this paper using the operational and performance data. These data are also used to briefly explain the extraction of parameters of the used model. Gas turbine parameters are approximated using simple thermodynamics assumptions. Though micro turbine power generation seems to be an uprising and a promising source, the exact design with a perfect model is only capable of producing the highest efficiency. Thus this paper is proposed on the aspects of social awareness to elaborate a mathematical model and a control design of the Micro Turbine Power Generation System. © Copyright 2016 American Scientific Publishers All rights reserved.

Developing countries like India have a huge supply-demand gap. Load shedding is very common during power shortages These outages cause extreme consumer discomfort. The consumer is also forced to have backup enough to meet his requirement. Frequent power outages also cause consumer ire and are a disincentive for the consumer to cooperate with any government initiatives. In this paper a simple and novel algorithm is presented wherein during power shortage, a partial outage is initiated for each consumer by giving weightage to sanctioned loads, load curve, revenue generated by the consumers with respect to the utility etc This algorithm is aimed at creating a win-win situation for the utility and the consumer, reduce consumer discomfort and dissatisfaction and also reduce the amount of back-up power investment by individual consumers. © 2016 IEEE.

Fault-tolerant multipliers with low power consumption are the need of today's computing systems and reversible circuits have emerged as an efficient solution for ultra-low power design. In this paper, we propose an improved Booth's recoding algorithm named as K-Algorithm for signed multiplication which reduces the hardware complexity. An efficient multiplier architecture for implementation of K-Algorithm is also proposed. Based on Booth's recoding algorithm, we design 4-bit reversible multipliers, with and without fault-tolerance. We also design a fault-tolerant reversible multiplier using K-Algorithm. We analyze all the three proposed designs using the reversible logic design metrics: quantum cost, number of ancilla bits, number of garbage outputs, and number of gates. We then compare our reversible multiplier designs with the existing designs reported in literature and find that on an average, our K-Algorithm based fault-tolerant design reduces the quantum cost by 33% and other design metrics are also considerably reduced. Overall, the proposed fault-tolerant reversible multiplier based on K-Algorithm is most optimal as compared to all other designs. © 2013 IEEE.

The energy demand of the human civilization is increasing day by day, which has made man to look for alternative sources, considering that the fossil fuels, which are the principal sources of energy, are depleting. In addition, the carbon footprint left over by fossil fuels has a detrimental effect on the earth's environment. This has entailed researchers to focus their attention to environment friendly and renewable energy sources. The primary considerations in this subject viz. solar and wind energy sources pose their own challenges to researchers, an essential component being their stochastic nature. Weather conditions, weather patterns and the site chosen have a direct impact on the effectiveness of the implemented system. A helping hand is extended by nature with the fact that the availability of these two sources is complimentary to one another, assuring a power source in all weather conditions. This has paved way for researchers to converge their studies on Hybrid power systems which employ multiple types of power generators to cater to the demand. A Predictive Power Management scheme which incorporates a forecast of the power generation capability of each generator, the load demand and other site-specific parameters is vital to extract the best of the implemented system. Such a management system, which makes a long term forecast, minimizing errors on the behavioral patterns of wind and solar energy has become a major subject matter of study for researchers across the globe. This paper gives an overview of the power management strategies. Different predictive power management topologies, advantages and challenges are discussed. © 2014 IEEE.

The increasing use of renewable energy sources necessitates accurate forecasting models for generation scheduling. Amongst the renewable sources, solar and wind have gained acceptance and are being increasingly used in distributed generation. The main problem with these sources is the dependence of their power output on natural environmental parameters at a given point of time. This paper proposes time series models for short-term prediction of solar irradiance from which solar power can be predicted. The predictions are done for 1 day ahead using different time-series models. For each model, these predicted values are compared with the actual values for the next day and graphs are plotted. Basic time-series models such as moving average and exponential smoothing were tested. The decomposition model is proposed, where the measured data is decomposed into seasonal and trend patterns and each of them predicted separately. The model was developed for different durations of data, to identify the best possible set of data. It is observed from the results that the prediction with decomposition model for 2 months data gave the best result with around 9.28% error. © 2015 Elsevier Ltd.

A single-hop network where a fusion center (FC) collects data from a set of energy harvesting nodes is considered. If a node that is scheduled has data and sufficient energy, it makes a successful transmission. Otherwise, the channel allocated to the node remains idle. The goal is to make efficient use of channel resources in order to either (1) use all the energy that is harvested by nodes, or (2) stabilize all data buffers. In the absence of feedback from nodes about buffers or battery states, or prior knowledge of the statistics of energy harvest and data arrival processes, this is a Restless Multi-Armed Bandit (RMAB) problem. Despite the hardness of RMAB problems in general, a simple randomized policy achieves near optimality for this problem under a broad class of arrival processes for unlimited battery capacity. Moreover, there is almost no loss of optimality under a reasonable-sized finite battery assumption. © 2014 IEEE.

Lightning is the natural phenomenon which brings huge quantity of charge to earth. It is a well known fact that lightning mostly strikes elevated objects. It is found that significant amount of current is induced in the simple vertical down conductor when lightning strikes directly or in the vicinity. The steel rods in the steel reinforced concrete buildings act as down conductors. Therefore the current induced in them may affect the operation of sensitive electronic devices in the building due to interference. Hence it is required to determine the magnitude and the nature of lightning currents in them. Therefore present work is carried out to study the basic characteristics of lightning generated currents. The study was carried out with the assumption that there are no influencing components in the vicinity of the building and the lightning strike and electrical connections in the building are through cable ducts. Electromagnetic model is employed and NEC-2 is used for the numerical field computations. It is found that the large amount of current is induced in the pillars and beams of the building and it depends upon various pertinent parameters. © 2012 IEEE.

A two-dimensional, motion planning approach that derives inspiration from the formation of shadows by opaque objects in the presence of a Gaussian light source is presented. It utilises the 'potential field'-like varying intensity of a Gaussian light source coupled with the rectilinear property of light. The method borrows advantages of artificial potential field (APF) methods, such as single path generation and scope of feedback control. At the same time, with the selection of adequate parameters, this method is immune to the formation of critical points in the configuration space - a drawback associated with most APF-based methods. Simulations are carried out and results are presented to demonstrate the applicability of the approach. © 2011 The Institution of Engineering and Technology.
