    ABSTRACT: An artificial neural network (ANN) model was developed to assess the energy input-output prediction in dairy farms of Iran. Data used were culled from 50 randomly selected farms using face to face questionnaire approach. The energy input-output analysis was carried out for the parameters of ANN model. Based on performance measures, single hidden layers with 16 neurons in the hidden layer were finally selected as the best configuration for predicting energy output. In this study, we calculated total energy input and output to be 53,102 and 58,315 MJ cow<sup align="right"> −1 </sup>, respectively. The predicted values of the best and optimal structure of ANN model were correlated well with actual values with coefficient of determination (R<sup align="right"> 2 </sup>) of 0.88 and root mean square error (RMSE) of 0.015. Therefore, since the ANN model can accurately predict the derived energy output of milk production system, it could be alternated by other predicting approaches such as regression.

    ABSTRACT: Short term measure for dealing with energy crisis is reducing consumption by: 1) improving the efficiency of all energy consuming machines; 2) eliminating the wasteful use of energy. Renewable sources of energy such as solar, wind, tidal, waves, etc., do make a significant contribution to demand for energy but they are unlikely to meet the ever increasing consumption. Long term measures may require exploitation of hydrogen to replace fossil fuels or to opt for nuclear energy. Since 3/4 of the earth is covered with water, we have inexhaustible source of hydrogen to meet our energy needs. The purpose of this paper is to promote public awareness of the methods of large scale generation of electricity and to examine critically the pros and cons of both short term and long term measures.

    ABSTRACT: This paper presents a new method for accommodating loop flow in the process of transmission loss allocation including a generalised model for the transmission line. The developed line model is similar to the generalised circuit model based on the famous ABCD parameters. The proposed model enables unbundling the active power loss allocated to a node into two components; the first is the loss due to active power flow and the second is the loss due to reactive power flow. The same is done for the reactive power loss. Such separation of loss components makes loss allocation more transparent and explainable. In the presence of a loop flow, the power flow tracing algorithm gets faced with some nodes remaining in the system where no one of it is a pure sink node and hence gets stuck. The paper describes a method for loss allocation in the presence of loop flows based on signal flow graph manipulation techniques.

    ABSTRACT: Lithium Bromide (LiBr) strong solution entering the absorber tends to crystallise when the absorber temperature is increased for a fixed evaporating pressure. This is considered the key technical barrier for the development of a LiBr absorption heat pump water heater. There are several approaches to avoid the crystallisation problem, such as chemical crystallisation inhibitors, heat and mass transfer enhancement and thermodynamic cycle modification. This paper investigates and compares two flow configurations of LiBr absorption heat pump water heater to evaluate the allowable operating conditions for each. The simulation results indicated that introducing the process water through the absorber first results in lower absorber temperature and hence less tendency for crystallisation.

    ABSTRACT: Installation of capacitor banks proved to be cost effective approach to correct power factor in industrial plants. Optimum capacitance value that contributes to the maximum PF improvement varies from one system to another. Such value depends on the existing electrical system within the industrial plant. This paper provides industrial plants operators an optimisation model to correct and improve PF. This paper is supported by using both MATLAB programming and iteration loop technique. The Jordanian Petroleum Refinery Company is taken as a case study. Results indicate that PF improvement reached almost unity PF for this case, which yields to a reduction in the overall electricity bill.

    ABSTRACT: This paper presents a new configuration of a voltage and frequency controller for a stand alone pico hydro power generating system employing an Isolated Asynchronous Generator (IAG). The proposed controller is an Electronic Load Controller (ELC), which consists of a three leg IGBT (Insulated Gate Bipolar Junction Transistor) based Voltage Source Converter (VSC), a DC chopper and an auxiliary load at its DC bus. The neutral terminal for the consumer loads is created using a star delta transformer and the proposed system is modelled and simulated in MATLAB using Simulink and PSB toolboxes.

    ABSTRACT: The deregulated market is characterised by a number of power producers trying to sell electric power through bilateral agreements or power exchanges. Each utility follows its own pricing strategy and causes more price volatility and makes comparison difficult. This paper presents a general model to determine the optimal Electricity Price (EP) at the generator end point which motivates investment and provides quality power supply to the terminal point. The proposed model is formulated considering peak/off-peak loads, plant load factor, outages, breakdown maintenance, availability of the plant and penalty. The developed model is applied to a typical thermal utility in India to determine the EP.

    ABSTRACT: The pot hardware in continuous galvanising lines is prone to failure and needs to be replaced quite frequently which results in considerable loss of production time and high energy consumption. Galvanizing Energy Profiler and Decision Support Systems (GEPDSS) was developed to consider major energy consuming equipment in a typical hot dip continuous line which tracks the current production and energy consumption for up to three different processes. It can simulate a scenario to identify energy, cost, and productivity benefits obtained from energy savings measures and can evaluate the economic desirability of investment in new and improved pot hardware.

    ABSTRACT: Indian power industry is undergoing deregulation at a rapid rate. In this transition phase, it is now essential to design the most appropriate market and suitable pricing schemes for the power sector. In this article, a restructured electricity market model for future Indian power market is explained which is based on the institutional frame work – The Indian Electricity Act 2003. The activities of the three-tier market model and the entities involved in the power trading are discussed. Inter-regional and intra-regional congestion management scheme that provide comparable access to all users of the transmission system is proposed. Method for estimation of transmission charges to wheel electrical energy through transmission utilities is also proposed. The method is tested with a five region eleven zone Indian power system model and the results are illustrated.

    ABSTRACT: Oil and natural gas, Kuwait's only resources of primary energy are also the only revenues from which national income is derived, including foreign exchange. Local energy consumption, excluding feedstock for refineries, estimated to be around 15% is increasing year by year, thus, posing a serious threat to the sustainable growth and financial well being of the country. Energy policy makers in Kuwait recognised this situation well ahead of time and launched a comprehensive energy conservation program to reduce fuel demand and/or supplement sources of energy, such as renewable energy before three decades. This paper highlights the major achievements of this program and presents a series of recommendations for future implementation.

    ABSTRACT: The present paper deals with an econometric model to forecast future electricity requirements for various sectors of Indian economy. Following the analysis of time series of sectoral GDPs, number of consumers in various sectors and price indices of electricity, a logarithmic linear regression model has been developed to forecast long-term demand of electricity up to the year 2045. Using the historical GDP growth in various sectors and the corresponding electricity consumption for the period 1971-2005, it is predicted that the total electricity demand will be 5000 billion kWh, against a supply of 1500 billion kWh in the year 2045. This may lead to a disastrous situation for the country unless drastic policy measures are taken to improve the supply side as well as to reduce demand.

    ABSTRACT: The rapid pace of India's industrial development has altered the demand-supply situation for power generation and also set the process of opening up of markets by state regulators. In the backdrop of the expected growth rate of 9% envisaged for the Indian economy, power sector requires a capacity addition of 78,000 MW in the 11th Plan with the objective of 'power for all by 2012'. During fiscal year 2007, India's total energy shortage was 9.9% of its total requirements, and peak shortage was 16.6% of peak demand requirements, indicating the need for effective energy management. Most of the studies related to energy efficiency focus on demand side management (DSM), however, in this paper we propose that an integrated approach incorporating economic reforms, FDI, operational-efficiency improvement of existing power plants, introduction of new energy-efficient technologies and reduction of losses in T&D as practiced in India can be emulated by developing countries.

    ABSTRACT: In this paper two different types of solar cookers namely simple box-type and parabolic solar cooker with its focus inside cooker, is investigated experimentally. Experiments were done at roof top of Renewable Energy Lab, Department of Mechanical Engineering, Institute of Technology, Banaras Hindu University (BHU), Varanasi, India. For comparison, these two cookers were kept on a single platform to ensure the same solar conditions. The first cooker is flat plate box type solar cooker (SBC) made of steel. The second cooker namely solar parabolic cooker (SPC) consists of acrylic mirror sheet with reflectivity of 0.75. The energy and exergy efficiencies of both the cookers were experimentally evaluated and found similar to previous studies.
