proper operations of transformer have several issues such as; preventing of unscheduled removal’s, increasing of reliability and continues supply of consumer demand. this result would be obtained that load and harmonic orders of sensitivity transformer at intervals appropriate for next hours and days is predicted to by selecting optimal utilization coefficient, reduction life of transformer is ...

in the present work, the simultaneous effects of fuel injection rate and injection of air jet into the combustion chamber on exhaust emissions, combustion process and performance parameters in a direct injection diesel engine were investigated. in order to create an air jet, a design was presented in which a secondary chamber (air cell) was created inside the cylinder and was joined to the main...

in this paper, a novel control method for photovoltaic converter connection to the national gridis presented, so in addition to the injection control by solar arrays to the grid, this method cancompensate reactive power and harmonics in the load current. the system will be connected inparallel between the grid and load. the proposed system supplies all load power consumption(including active po...

In recent years several catastrophic power systems blackouts have occurred worldwide. Various reasons have been declared for these failures. Economical limitations due to power system restructuring restrictions, inadvertent operation of protective relays and inefficient design of conventional load shedding schemes are of the most important reasons causing these blackouts. In fact, due to both e...

In the field of power systems there is an active research on methods to limit the peak load of power demand. Recently, a new approach to the automatic management of electric loads has been proposed, which is based on scheduling techniques derived from real-time computing systems. The research on real-time scheduling encompasses several aspects, including scheduling algorithms and analysis techn...

Borealis is a distributed stream processing engine that has been developed at Brandeis University, Brown University, and MIT. It extends the first generation of data stream processing systems with advanced capabilities such as distributed operation, scalability with timevarying load, high availability against failures, and dynamic data and query modifications. In this paper, we focus on aspects...

Any use of energy in industrial productive activities is combined with various environment impacts. Withintransportation, this fact was not only found among land transport, railways and maritime transport, but also in the air transport industry. An effective climate protection requires strategies and measures for reducing all greenhouses gas emissions, in particular carbon dioxide, and must tak...

Several peak load management strategies are being widely employed in the residential sector, due to increased energy consumption and peak demand. The residential peak demand is very prominent and largely depends on the interaction between occupant’s energy consumption behaviour and appliance usage, hence the need to address end-use appliance usage based on consumer utilization pattern. This pap...
