  • Grid integration of renewables in Egypt

    Integration of large Amounts of Renewable Electricity in the Egyptian Energy Grid - Capacity Building for Management and Engineer-Technical Level (Egypt-RE-Grid). The electricity sector of the Arab Republic of Egypt produces large amounts of electricity through thermal and hydroelectric power stations. Egypt has diminishing proven oil reserves and declining production. Natural gas production is ...

  • GIVS: integrity validation for grid security

    In recent years, grid computing has been recognised as the next step in the evolution of distributed systems. However, only limited efforts have been made to address the security issues involved in these architectures. Questions like 'What happens if a user of the grid is interested in making the overall computation fail?' are still unanswered. In this paper, we address the problem of granting ...

  • Integration of embedded generation in local grid using STATCOM

    The renewable sources of energy are being connected to the local distribution system/local grid leading to embedded generation. As these sources are intermittent in nature, they impose technical challenges in the power system operation which include power quality related problems of local grid. The performance of the system has to be evaluated while connecting these sources to the local ...

  • A grid-based integrated surface–groundwater model (GISMOD)

    A distributed hydrological model, the Grid-based Integrated Surface-groundwater MODel (GISMOD), was developed to simulate hydrological processes by considering water interaction among different soil layers. The model integrates six modules. Basic information on catchment, such as the flow direction and the drainage network, can be obtained automatically from digital elevation model (DEM) data ...

  • An Action Plan to Integrate Plug-in Electric Vehicles with the U.S. Electrical Grid

    Executive Summary: Americans purchased almost 18,000 plug-in electric vehicles (PEVs) in 2011, a strong first year for these transformative vehicles. Recently, private industry and government have invested valuable resources in developing, promoting, and deploying PEVs. These vehicles offer an uncommon opportunity to address energy security, air quality, climate change, and economic growth. ...

  • What will it take to integrate renewables into the power grid? Ask a bicyclist.

    When it comes to fitting into the current system, bike commuters and electrons have a lot in common. There’s nothing quite like biking down clogged city streets, weaving in and out of traffic. For short distances, it’s faster than driving. It’s liberating. It’s fun. It also makes it painfully clear that most roads ...

  • Smarter grids, appliances, and consumers

    More and more utilities are beginning to realize that building large power plants just to handle peak daily and seasonal demand is a very costly way of managing an electricity system. Existing electricity grids are typically a patchwork of local grids that are simultaneously inefficient, wasteful, and dysfunctional in that they often are unable, for example, to move electricity surpluses to areas ...

  • A grid for subgrade stability

    With research to back up quantifiable benefits and recognized design standards, the use of geogrids may be ready for wider acceptance among North American railroads. A product with a 20-year plus track record is rarely referred to as "new." However, this is a label those involved with geogrids find themselves tagged with when it comes to the prod¬uct's use on North American railroads. While ...

  • Integration of wind-generating units into the Corsican electrical grid: determination of the maximal integration rate from a reliability analysis based on a stochastic process

    This paper investigates the potentiality of Wind Electric Conversion Systems (WECS) integrated into the islander electrical grid of Corsica. Probabilistic models for WECS and their use in the reliability studies of combined wind electric and conventional generation systems are discussed. The method, based on the evaluation of the Loss of Load Probability (LOLP), uses a Markov model applied to the ...

  • A comparative study on the grid integrated wind energy conversion systems (WECS) using different generator models

    A huge number of wind generators are going to be connected with the existing network in the near future. Therefore, it is necessary to analyse various models of wind energy conversion systems (WECS) for the purpose of studying the impacts upon grid. This paper presents comparative study on grid connected WECS having two different wind turbine generator systems (WTGS): model 1 [WTGS having doubly ...

  • Economics of large-scale intermittent RES-E integration into the European grids: analyses based on the simulation software GreenNet

    Market integration of Renewable Energy Technologies for Electricity (RES-E) generation is one of the core topics in the energy policy agenda of the European Commission (EC). However, legislation in this context still faces a variety of lacks (e.g. ignoring unbundling principles) in almost all countries of the European Union (EU). The recently finished EC-Project GreenNet addresses these existing ...

  • The design and prototype of RUDA, a distributed grid accounting system

    The grid environment contains a large and growing number of widely distributed sites with heterogeneous resources. It is a great challenge to dynamically manage and account for usage data of grid resources, such as computational, network, and storage resources. A distributed Resource Usage Data management and Accounting (RUDA) system is designed to perform accounting in the grid environment. RUDA ...

  • Hourly water demand forecasting for micro water grids

    Many countries have problems related to water scarcity and are thus seeking to promote greater water efficiency. A micro water grid (MWG) is a high-efficiency water management system that integrates information and communication technologies (ICT) for the water distribution systems in individual buildings. More accurate forecasting of hourly water demand is necessary if these systems are to ...

  • High Penetrations of Renewable Energy for Island Grids

    Island grids represent an overlooked opportunity for renewable power. In addition to geographical islands there are also many electrical islands, such as remote locations throughout the world, where interconnections with neighboring grids are not a practical option. Due to transportation issues and the lack of economies of scale, these grids typically rely on liquid fuel derived from petroleum. ...

  • Biomethane enters the gas grid article for energy world

    The Carbon Plan, published in 2011, aims to reduce UK carbon emissions by a quarter from 1990 levels. With the current policies in place, the UK is on target to reduce emissions by over a third by 2020 and with the introduction of new technologies this should increase to an 80% reduction by 2050. However, currently around half the UK’s carbon emissions result from heat related processes and ...
