Depleting fossil fuels and ever-increasing environmental have attracted much attention to the renewable energy resources. The Micro-Grid (MG) concept is an appropriate means for increasing the adaptation of these resources with current power system architecture. In this paper a new method is used to solve the problem of unit sizing in a grid-connected MG providing electrical and thermal loads ...

Nowadays, the high rates of energy consumption of buildings in contemporary societies, as well as in global problematics such as climate change, depletion of natural resources and environmental pollution, is widely recognized. In this context, energy efficiency of buildings has become a crucial aspect of national and international energy policies. Nevertheless, the design of high performance bu...
