  • Gas distribution network for households in Saudi Arabia: economic and demand estimation studies

    This study evaluates the economics of establishing a residential natural gas network in Saudi Arabia's Eastern Province (EP) to cater to the household demand for natural gas. The paper focuses primarily on household use of natural gas for cooking. Additional economic analysis of other household uses – as air conditioning, space and water heating – is incorporated. Demand streams of various ...

  • Life-cycle assessment of common water main materials in water distribution networks

    This paper examines the economy-wide environmental impacts linked to the manufacturing of PVC and ductile iron (DI) pipes, steel tanks, and to the generation of electricity for pumping in water distribution network optimization. The non-dominated sorting genetic algorithm (NSGA-II) is used to generate Pareto-optimal solutions of the benchmark ‘Anytown’ network expansion problem. Selected ...

  • Adaptive locally constrained genetic algorithm for least-cost water distribution network design

    This paper describes the development of an adaptive locally constrained genetic algorithm (ALCO-GA) and its application to the problem of least cost water distribution network design. Genetic algorithms have been used widely for the optimisation of both theoretical and real-world nonlinear optimisation problems, including water system design and maintenance problems. In this work we propose a ...

  • Energy efficiency in water distribution systems – a path to an ideal network: AGS experience

    Infrastructure asset management (IAM) gave a step forward in Portuguese water utilities due to recent legal obligations in developing IAM plans. An effort was made by AGS (Administração e Gestão de Sistemas de Salubridade, S.A.), private operator in 17 water utilities, to achieve a higher level of managing data. Data management was an important hurdle to be overcome in order ...

  • Developing Decentralised Distributed Generation in Africa

    Many countries in the developed world created power generation networks based upon large centralised power generation stations with significant investment in power transmission and distribution networks. From the African context this has not happened yet there is a huge need to increase power generation capacity. The thought of addressing this through a small number of large gas, ...

  • Distributed Measurements Unlock the Future of Design

    The next generations of materials and design will require sensing technologies that can monitor beyond the scope of point sensors such as thermocouples and strain gauges. New sensing platforms based on optical fibers can obtain spatially continuous, real time data, giving developers detailed insight across broad areas into how their materials and designs behave. Such systems also can sense ...

  • The Need for a Total View of Water Networks

    The water industry is not short of software offerings, and so the arguments in favour of yet another software program had better be very good indeed. In this article we examine how one very significant community of users – operations managers, engineers and planners - have largely had their specific needs overlooked; we identify the type of system needed to fulfil their requirements and the ...

  • An efficient coupled GA and load flow algorithm for optimal placement and sizing of distributed generators

    A genetic algorithm is used in conjunction with an efficient load flow programme to determine the optimal locations and sizing of the predefined DGs within MATLAB software. The best location for the DGs and the sizing of the DGs are determined using the genetic algorithm. The branch electrical loss is considered as the objective function and the system total loss represent the fitness evaluation ...

  • Reducing life-cycle carbon footprints in the redesign of water distribution systems

    Water distribution systems (WDSs) contribute to undesirable greenhouse gas (GHG) emissions that are generated through their component fabrication, construction, operation and disposal processes. The concentration of GHGs in the atmosphere is strongly associated with global warming and climate change. In order to meet the consequent challenge of limiting GHG emissions, the problem of WDS redesign ...

  • Water network sectorization based on a genetic algorithm and minimum dissipated power paths

    Water Network Sectorization (WNS) consists of dividing a water system into sectors with an independent water supply. When each district is supplied by its only water source the districts can be defined as i-DMAs (isolated District Meter Areas) because they are completely cut off from the rest of the water network. This isolation of the i-DMAs may decrease hydraulic performance of the water ...

  • Discussing the Impact of the Various Catastrophic Tornadoes on the Transmission & Distribution Systems

    Utility preparations for outage response and restoration are an ongoing, consistent problem. Through the year, storms cause disruption to the delivery of power and ultimately cost the utility industry money through lost revenue and system repair. Much of this preparation is focused on weather damage that may occur from hurricanes, thunderstorms, ice storms and various other natural events. Pam ...

  • Energy recovery potential using micro hydropower in water supply networks in the UK and Ireland

    The supply and treatment of water is a highly energy intensive process, resulting in large amounts of greenhouse gas emissions as well as incurring large economic costs. Both governments and water service providers worldwide recognise the need for more sustainable water supply systems. In recent years, the use of hydropower turbines within water supply networks has been shown as a viable option ...

  • Background: EU electricity and gas directives

    3.rd Energy Market Package, proposed September 2007 September 2007 the EU Commission proposed a revision of the electricity and gas market directives with amendmets of the directives on electricity and gas markets and the directives on cross-border trade of electricity and gas. The main changes are that all countries must have independant regulators of the electricity and gas markets, that these ...

  • Gas reticulation optimisation for domestic sector in Malaysia

    Gas distribution has become increasingly important in Malaysia as most of the new housing areas have installed this piping system. A gas network analysis and design computer program with the determination of coincident factor has been developed to optimise the gas distribution system. The optimum and practical gas coincident factor are determined from gas consumption data of several residential ...

  • Italy Oil and Gas Report Q1 2013

    Aside from the country’s well-publicized economic woes, Italy is at a crossroads in terms of energy market development. The public has rejected state efforts to revive its nuclear strategy, leaving the way clear for gas volumes to rise steadily higher – forcing the import bill up at the same pace. Domestic oil and gas volumes are significant, with some upside potential, while ...

  • Identifying Leaks from Natural Gas Pipelines at a Safe Distance

    The use of natural gas, of which methane is the principle component, is increasing worldwide. According to the American Petroleum Institute methane meets 24% of U.S. energy demand and heats over 50% of all U.S. households. It also has many industrial uses, such as the manufacture of chemicals like ammonia, methanol, butane, ethane, propane and acetic acid; it is also an ingredient in products as ...
