Performance evaluation and optimisation of operating parameters of gas power plants are the key challenges for the researchers and the power plant designers. Traditional performance evaluation techniques being utilised operate on the first law of thermodynamics. Exhaustive studies in this area suggest scope of improvement in view of power output, thermal efficiency and cost effectiveness through more valuable evaluation techniques as second law analysis, exergoeconomic analysis and evolutionary algorithms. In this perspective, energy, exergy and exergoeconomic investigations of the gas power plant are executed in context with 1st and 2nd laws of thermodynamics. The multi-objective optimisation is also performed using NSGA-II and MOPSOCD evolutionary algorithms in MATLAB 9.2 in order to explore best input parameters and to find best trade off amongst two challenging objectives. The validation of the present work is done by correlating the obtained outcomes with 137 MW running gas power plant, Faridabad, India. The analysis illustrates a considerable enhancement in exergy efficiency of the power plant (around 18%) with a drop-in cost of the fuel and product as 15.72% and 13.24% respectively. However, total capital cost is increased by 10.61%.

In the present context, renewable energy sources are recognised as the best alternative of fossil fuels in order to fulfil the ever increasing demand with minimum harmful impact on environment. The combination of renewable energy sources can also be used in grid connected environment. This will help in reducing the burden of increasing demand on grid. Also, utility grid can supply deficit demand in case available generation from renewable energy sources becomes less than the demand. In the present paper, intelligent modelling of grid connected hybrid system has been carried out. Further, the total net present cost (NPC) of the considered system is optimised under the constraints of power reliability, storage limit on battery, etc. Finally, a comparative analysis has also been performed between the grid connected and standalone hybrid system based on the size and cost of components.

Smart metering, a subset of the smart grid architecture has evolved over the years as power system infrastructure demand efficient energy management initiative. The basic challenge of inefficient energy utilisation and energy wastage in consumer premise in an energy saving driven society has led to the development of smart metering solutions. This paper therefore provides a review on smart metering technology, its' design requirements, protocols and challenges, policy issues.

The objective of this study is to provide empirical evidence on the relationship between rural and urban population on electricity consumption in five Sub-Saharan countries between 1971 and 2013. Results from the autoregressive distributed lag (ARDL)-bounds testing approach indicate that rural population plays a larger role in electricity consumption than the urban population in Cote d'Ivoire, Congo Republic and Zambia. In Congo Republic, a 1% growth in rural population resulted in a 29.4% decline in growth of electricity consumption in the long run. Growth in rural and urban population does not affect electricity use in Kenya and South Africa.

Iran has always been the importer of gasoline over the last decade and international sanctions have made imports of this commodity potentially constraint. This condition as a supply constraint can damage the production of other economic sectors through rising in production prices and changing Iranian household welfare. Thus, a key question in this regard is how Iranian household expenditures will be affected in different consumer groups if the gasoline supply is constrained. To answer this question, the mixed-variable input-output price model and a symmetric Iran 38 × 38 input-output table for the year 2005 were employed. The results showed that most of the poor urban groups, especially the first eight groups, show a high sensitivity to the rise in gasoline prices and reduction in their overall expenditures. Nevertheless, rural households, unlike urban households, are heavily dependent on gasoline consumption, and do not reduce their expenditures in response to price changes.

Energy intensity level in Indonesia is decreasing, which is a sign of energy efficiency improvement. However, with the presence of rebound effect, energy consumption becomes challenging to reduce. With a general equilibrium (CGE) model application, this study analyses a rebound effect existence in Indonesia and whether the energy subsidy and income tax reduction could lessen the rebound effect. While it confirms the rebound effect presence, energy subsidy reduction policy could play an important part in determining its level. The policy is believed to reduce rebound effect on fuel oil while elevates it when it comes to electricity and gas. Furthermore, it leads to a positive effect on the economy. However, the other policy such as income tax reduction, indicates contrarily.

Projections of long-term wind-powered electricity by the Energy Information Administration in the past may have been too conservative. We generate alternative projections for China, USA, India, Canada, Japan and South Korea, and compare them against the projections made by the Energy Information Administration (EIA) for the years 2020, 2030 and 2040. Although our projections are much higher than the EIA's for five of the countries, the exception being Japan, our projections are supported by several projections made by other organisations. Implications from our findings will be discussed.

The British Isles are blessed with one of the largest resources of offshore wind energy in the world. A scenario simulation is used to demonstrate that not only can each society within the British Isles area in a matter of a few decades (say around 2050) develop an energy system to satisfy all energy demands with 100% renewable energy, but there are further export opportunities to cover more than the entire electricity needs of the continental European Union (EU). The political implication of this is that it would be very foolish of the European Union not to use the Brexit negotiations to establish a friendly relationship with the UK that can open for the electricity imports without which it will be very difficult for the continental EU to reach an emission-free and sustainable energy system.

This paper focuses on the intelligent techniques used for tracking the maximum power point of the solar photovoltaic (SPV) system for varying environmental conditions. The most widely used perturb and observe (P&O) maximum power point tracking (MPPT) technique is discussed briefly for the comparison with the intelligent techniques. The paper proposes control technique for the SPV system by using fuzzy logic controller (FLC)-based MPPT algorithm and the optimisation of its various parameters by genetic algorithm (GA). The performance of the FLC optimised with GA is compared with the P&O and the fuzzy-based MPPT technique. MATLAB/simulink software is used to design the different stages of the MPPT controllers. Simulation results reported that GA optimised FLC perform much better than the P&O and fuzzy logic-based MPPT controllers.

The Middle East is one of the biggest suppliers of energy resources in the world. Through electricity production, transportation, oil and gas industries, industrial heating, the quality of air, environment and the whole economy at large is being affected. It is on this premise, this study examine the long-run equilibrium relationship and Granger causality interaction between CO2 emissions, income per capita and energy use caused by these traffics. We employ second generation panel approach that account for cross-sectional dependency, panel bootstrap cointegration testing as introduced by Westerlund and Edgerton (2007) and Granger causality testing procedure as proposed by Dumitrescu and Hurlin (2012). These econometrics techniques are robust for panel cointegration and panel Granger causality analysis. From our empirical results, we found evidence in support of a long-run equilibrium relationship among the variables, a bidirectional causality running from CO2 to energy use, and unidirectional causality running from CO2 emissions to income per capita. However, between income per capita and CO2 emissions, income per capita to energy use and energy use to income per capita all without a feedback in the long-run. We propose significant policy implications based on our empirical results.
