In recent years, power grid infrastructures have paved way for decentralized topological layout where distributed power generations are surfaced at the point of consumption to gain higher sustainability factor while truncating power outage problems. In consequence, researches have begun infusing various methodologies with several advance heuristic optimization algorithms to provide superior power...
This paper is about economic dispatch with PV generation including transmission losses considering emission as constraint using particle swarm optimization. This objective consider the minimization of fuel cost with emissions constrained of thermal generating units with scheduling for sharing of different photo-voltaic generating units to fulfill the load demand in such a way to minimize the total...
The article provides a method of assessing the effectiveness of CHPP units based on differential-exergy method. Technical and economic indices of CHPP operating regime such as unit exergic efficiency electric power and thermal exergy delivering, technical and economic exergy efficiency, the specific costs of electrical energy and thermal exergy are considered. These indices can extend traditional...
In this paper, a fully-constrained five objective multi objective dynamic economic emission dispatch (MODEED) problem with thermal, wind, solar, line losses and emissions is considered. More accurate cubic cost functions for thermal, losses and emissions objectives and high potential renewable energy (RE) have been used. Modified Firefly Algorithm with Levy Flights and Derived Mutation (MFA-LF-DM)...
In this paper, we investigate the effect of the wind energy in electrical power system on economic dispatch. An economic dispatch problem considering wind power injection is formulated and solved by Simulated Annealing (SA). To show the advantages of the proposed algorithm, it has been applied for solving economic load dispatch problem in a 3-generator system with transmission losses and gas emission...
Hybrid renewable energy systems shows a great potential for electricity generation in Bangladesh. Hybrid renewable energy system can be set up such a way that the electricity will add to national grid connection and it will eventually reduce the pressure of electricity demand from national grid. Abundance of renewable energy sources in the form of solar energy provides opportunities of renewable energy...
Many renewable energy (RE) projects cannot compete with conventional energy projects in terms of economics alone. However, if externality costs of competing technologies are carefully evaluated and taken into account the renewable energy projects are likely to be selected on economic basis. But the problem is the evaluation of externality costs which are not always easy to assess. One way to overcome...
There is a broad variety of ecological audits, which can be considered in production or disposal processes. None of them have been adapted to inventory planning. In this paper an approach of combining sustainability aspects with spare parts ordering will be presented. It is investigated how costs for CO2 emission must change or have to be changed by governments in a way that sustainable spare parts...
Power utilities strive for optimal economic operation of their electric networks while considering the challenges of escalating fuel costs and increasing demand for electricity. The dynamic economic dispatch (DED) occupies a prominent place in a power system's operation and control. It aims to determine the optimal power outputs of on-line generating units in order to meet the load demand subject...
Decomposition analysis has been popular in the study on influencing factors of CO2 emissions. This paper analyzes the change of CO2 emission intensity in China over the period 1980-2007 based on a complete decomposition approach-the logarithmic mean divisia index (LMDI) method, and examines the factors driving the changes of CO2 emissions intensity. The research shows that energy intensity is the...
The UK Government plans that offshore wind power should play a major part in meeting the UK's renewable energy and carbon emission targets by 2020. The pioneer UK Round 1 offshore wind farm projects, based on sites let in 2001, were supported by the UK Department of Trade and Industry's “Offshore Wind Capital Grants Scheme”. This paper reviews the economic and operational performances of those farms...
Concern over global climate change has led policy makers to accept the importance of reducing greenhouse gas emissions. This in turn has led to a large growth in clean renewable generation for electricity production. Much emphasis has been on wind generation as it is among the most advanced forms of renewable generation, however, its variable and relatively unpredictable nature result in increased...
The MicroGrid concept using renewable energy sources is a building block towards the future energy networks for long-term viable solution of energy needs. The focus of the paper is centred around the encountered and foreseen issues, enabling technologies and economics for encouraging the deployment of MicroGrids in India. This paper presents state-of-the-art issues and feasible solutions associated...
A huge opportunity exists within the electricity generation industry to reduce greenhouse gas emissions, thus making a significant contribution to climate change mitigation. Under the European Union Emissions Trading Scheme (EU ETS), member countries are allocated national emission quotas which they further distribute among their individual industry sectors. Within the UK, the electricity generation...
