Output power in a hybrid power system is constant while the input power with variable characteristics that is generated by different sources. Using Hybrid Electrical Energy Storage (HEES) systems, is growing rapidly since there is an obvious need for clean energy. This paper introduces different parts of a HEES system and then proposes HEES systems which employ battery, ultracapacitor and f...

Abstract Different dynamics can be observed between the renewable and fossil energy markets, suggesting need for different approaches in theoretical practical field of security. However, context current transition, there is a geographic concentration production chains new clean energy-generating equipment, which creates dependencies inputs commercial partners. Consequently, security affected by...

from 60 decade  sustainability issues  and sustainable developing  have opened a way in scientific meetings associated with  environment and urbanization and architecture. sustainability goals are improving of environment situation , less pollution  and at least interference on  land and interaction of  natural and artificial environment , that most of these cases attracted attention in archite...

Nowadays, Most of the cities, especially metropolises of developing countries are engaged with environmental issues like air and water pollution, waste increase and etc., that lead to the environmental destruction. Meanwhile sustainable urban development, provides the balance between development and the environment, and supplies the current generation needs while keep its eyes on the next gener...

Clean and sustainable renewable energy technology is going to take responsibility of energy supply in electrical power systems. Using renewable sources improve the environment and reduce dependence on oil and other fossil fuels. In distribution power system, utilizing of wind and solar DGs comprises some advantages; consist of loss and emission reduction, and also improvement of voltage profile...
