the use of renewable energy in power generation and sudden changes in load and fault in power transmission lines  may cause a voltage drop in the system and challenge the reliability of the system. one way to compensate the changing nature of renewable energies in the short term without the need to disconnect loads or turn on other plants, is the use of renewable energy storage. the use of ener...

Recent studies have shown that the Information and Communication Technology (ICT) industry is responsible for about 2% of the global emission of CO2 and this percentage is expected to increase as the internet expands in bandwidth and reach. In this paper we propose a hybrid-power IP over WDM network where renewable energy is used to reduce the CO2 emission of IP overWDM networks. ALinear Progra...

Nowadays energy is one of the most essential needs of human being and it can be considered as the basic prerequisite of social and economic development.  Hence, many of the correlations and legislations of a country are affected by it. Since Iran has huge source of gas and oil, it has turned to a fossil fuel oriented county. But as oil and gas sources are non-renewable ones and cannot be replac...

Introduction Improvement of the energy industry in developing countries is the major basis of the process of techno-economic and socio-cultural development. This improvement requires the transfer of energy technology which is dominated by non-renewable energy systems. Natural resources which are mostly non-renewable, on the other hand, face various threats caused by such a process of developmen...

The probably biggest challenge for climate change mitigation is to find a secure low-carbon energy supply, which especially is difficult as the supply of renewable sources underlies strong volatility and storage possibilities are limited. We therefore consider the energy sector of a small country that optimizes a portfolio consisting of fossil and/or renewable energy to cover a given energy dem...
