The growth of power generation based on natural gas fired power plants (NGFPPs) in the recent years has lead to increasing interactions between electricity and natural gas systems, which can be used as a competitive advantage for an agent operating in both markets. Therefore, the larger is NGFPPs consumption the larger is the interdependence between electricity and natural gas systems, and the analysis...
Greenhouse gas emissions (GHG) and the resulting global warming ignited an intensive debate and work on energy consumption, GHG emissions and the overall environmental impact assessment of the Telecom industry and the ICT sector. Initial studies focused on GHG emissions caused by the energy consumption during the use phase, followed by a more detailed analysis of GHG emissions during the complete...
The proposed system focusses on development of low power and low cost electric energy meter reader. The system consists of two modules, measurement and communication module. The measurement module measures the line current and voltage in order to measure wattage and finally energy. Current transformer (CT) senses the line current while the potential transformer (PT) measures the line voltage. The...
This work presents an evaluation of the new time-of-use tariff that is being implemented in the Brazilian electricity distribution segment, called White Tariff (WT). It is a three band tariff and is applied to low voltage consumers, who can choose to migrate to the new tariff. The assessment is in the context of expansion projects. The main question answered in the paper is about the possibility and...
With global energy market liberalization, the demand for electricity is essential information for electrical companies. The need for electricity is expressed with the demand for electric power in function of time. The purpose of this paper is to find a mathematical model for the relation between electric Power and Time, using linear regression through the programming language R. In order to find this...
The vehicle-to-grid (V2G) framework proposes integration of battery-powered electric drive vehicles into the grid, enabling them to be recharged as necessary and to act as suppliers in the ancillary service electricity markets. This is expected to create incentives for the production and adoption of electric vehicles in the automotive industry. V2G frameworks require that the utility company or a...
South African industries are facing worrying cost implications related to their electricity usage. These include carbon tax, increased reactive power charges, unavoidable tariff increases and the Energy Conservation Scheme (ECS). Some of these proposed schemes and increases are not enforced yet, but pose a threat to the financial well-being of large key customers such as the gold mining industry....
The East African region has been undergoing fast economic growth particularly as demonstrated by its resilience against the effects of World recession since 2008. This is particularly true for Uganda. Sustaining this growth will however require affordable and reliable power supply which is currently a major challenge. World-over the “smart grid” concept is poised to transform the way energy is generated,...
According to the technical progress and that of the New Information and Communication Technologies (N.I.C.T.), the increasing complexity of the production equipments, and the competitiveness world, which involve the research of the total quality and cost cutting, the traditional functionalities of the industrial company evolve to more flexible and interactive functionalities. The New information and...
Mobile Telephony Technology (MTT) has successfully diffused in Uganda with minimal government intervention, unlike Modern Energy Technologies (MET) that remain outside the reach of most Ugandans despite massive government interventions. Low access to MET seems to be contributing to Uganda's underdevelopment and unemployment. Projects initiated to spur MET diffusion haven't been very successful, and...
Like any other industry sector in Morocco, the electric power industry is facing challenges involved with the increasing demand for interconnected system operations and control under the restructured electrical industry due to deregulation of the electrical market and the trend of the Smart Grid (The Ministry of Energy, Mines, Water and Environment for Morocco has launched in 2011 a consultation for...
Currently there are actively developing services implementing Internet of Things [1]. Such services allow to delegate controlling and monitoring tasks over heterogeneous devices to the cloud. Because of interconnectivity, connecting devices to single cloud opens up new possibilities in controlling complex systems based on real-time data analysis, predicting accidents, etc. In this paper we will describe...
The paper suggests an energy efficiency benchmark for a high level monitoring in order to fulfill the energy efficiency goals of the federal government in Germany until 2020 and 2050. Based on statistical energy consumption data of the industrial sectors according to the NACE-Code classification, energy efficiency can be evaluated on different abstraction levels, resulting in aggregated indicators...
This paper presents a new methodology for enhancing the distribution system performance by minimizing both technical and non technical losses. Most of the utility companies in developing countries are victims of major revenue losses due to technical and non technical energy losses. The non technical losses are like electricity theft, unauthorized connections, irregular billing and the technical losses...
The energy portfolio and production planning problem for multiple companies under energy constraints is formulated as a mixed integer nonlinear programming problem. A new Lagrangian decomposition and coordination approach is proposed to solve the problem effectively. In this paper, we propose efficient computation algorithms for lower bound and upper bound. The lower bound is computed by relaxing...
This paper presents a small urban plug-in hybrid electric vehicle whose propulsion architecture includes a conventional internal combustion engine connected with a continuously variable transmission in the front wheels and two in-wheel electric machines in the rear wheels. Various operation modes, including zero emission vehicle mode, boost mode, and regenerative braking mode, are possible with this...
The development of an innovative waste-to-energy plant in rural South Africa is now underway. A plan to construct a test unit that uses chicken droppings from a nearby chicken farm as a fuel source is presented. This waste-to-energy plant offers an opportunity to provide economic development and community empowerment. The system is based on two critical components: (1) a power generation plant which...
Because of global warming and shortage of fossil fuels, much attention has been paid to plug-in electric vehicles (PEVs) worldwide in recent years. With possibly millions of PEVs on road in the future, it is essential for power network operators, especially distribution network operators, to implement coordinated PEV charging. In this paper, an optimal charging method is proposed for PEVs to maximize...
The project consists of the installation of an environmentally sustainable habitation module for a vulnerable sector (In this case “Kyrios”, Rehabilitation Center); the module was built with waste plastic materials from different companies' packaging processes. A photovoltaic system and a solar collector were included as well to meet electricity and thermal energy demands respectively. To guarantee...
Private houses are more and more enabled with devices that can produce renewable energy, and the not so remote chance of selling the surplus energy makes them new players in the energy market. This market is likely to become deregulated since each energy home-producer can negotiate the energy price with consumers, typically by means of an auction; on the other hand, consumers can always rely on energy...
