The proposition of Power Quality Intelligent Information System provide an effect ive platform for the monitoring, analysis and processing to all kinds of power quality problems in Smart Grid.However,with the acceleration of Smart Grid construction,continue increasing of the amount of power quality monitoring sites and gradually improving of the system,various types of monitoring and calculatin...
Cloud Computing, the long-held dream of computing as a utility, has the potential to transform a large part of the IT industry, making software even more attractive as a service and shaping the way IT hardware is designed and purchased. Virtualization technology forms a key concept for new cloud computing architectures. The data centers are used to provide cloud services burdening a significant...
Growing demand for electricity and the reduction of fossil fuels have made it essential to consider alternative and renewable energy sources, such as solar and wind, to generate electricity. In this paper, by computing levelized output energy cost and levelized cost of electricity, the prices of electricity generated from the different combined cycle, wind, and photovoltaic power plants are com...
in this paper power system model is represented in a new domain that relates to multi-resolution analysis (mra) space. by developing mathematical model of elements in this space using galerkin method, a new alternative method for power system simulation in nonsinusoidal and periodic conditions is developed. the mathematical formulation and characteristics of new proposed space is expressed. als...
power transformers are important equipments in power systems. thus there is a large number of researches devoted of power transformers. however, there is still a demand for future investigations, especially in the field of diagnosis of transformer failures. in order to fulfill the demand, the first part reports a study case in which four main types of failures on the active part are investigate...
in this paper the problem of minimizing the total transmitting power subject to a fixedtotal bit rate in ofdm systems is considered. upper bounds on transmitting power and bit rate ofeach subcarrier can also be taken into account. in practice, the number of bits of each subcarriershould be integer and nonnegative. in this paper an analytical optimal solution is derived for thecase of assuming t...
it’s not long since the advent of pervasive computing by mark weiser and one of its main usages is in healthcare systems. as this technology has been introduced only recently in this field and because we are dealing with peoples’ lives and their data, providing a high level of privacy and security is of great importance. various studies have been performed in which a certain method has been use...
to evaluate and predict component-based software security, a two-dimensional model of software security is proposed by stochastic petri net in this paper. in this approach, the software security is modeled by graphical presentation ability of petri nets, and the quantitative prediction is provided by the evaluation capability of stochastic petri net and the computing power of markov chain. each...
