For over the past several decades, there has been a great concern about energy crisis and lackof non-renewable resources. Residential buildings take more than 25% of the total energy consumption and morethan 75% of energy consumption in these buildings is for heating, cooling and hot sanitary water. On the other hand,traditional buildings of Iran were designed according to ecological conditions...

concerns related to climate change and security of energy supply is pushing various countries to make strategic energy planning decisions. in this regard, energy system modelling is an appropriate method to find out the utilization of current declining non-renewable energy resources and other possible scenarios. consequently, it is available to consider various aspects of energy system decision...

With the larger penetration of variable renewable energy resources, the role of energy storage in the power system is becoming increasingly important. The flexibility of operation of hydro and pumped-storage power plants and the variety of ancillary services that they provide to the grid enable better utilization of variable renewable resources and more efficient and reliable operation of the e...

The continuous use of fuels like petroleum is recognized as unsustainable because of their natural exhaustion and contribution to the pollution in the environment. Not only for the environmental perspective but also for the economic sustainability, we necessarily need to develop alternative, renewable and pollution free fuels. Harvesting energy from the sun (solar energy), earth (geothermal ene...

biomass co-firing with lignite represents an attractive solution for operating lignite-fired thermalpower plants (tpp) with the dual advantage of using local renewable resources and simultaneously reducingemissions. the subject of this study is technical and environmental investigation of the feasibility of the cofiring of soma lignite with some dried agricultural residues in the soma thermal p...

The leading cause of climate change today is the burning of fossil fuels related to energy production. One approach to reducing greenhouse gas emissions, therefore, is to more actively switch to renewable technologies in the production of electricity, and reduce the use of fossil fuels in electricity production. This is the goal of renewable portfolio standard (RPS) legislation, currently in ef...

Power plants experience distinct dynamic behaviors according to the primary source of energy. Whereas thermal power plants have a slow dynamic, modern renewables such as wind and solar PV are subject to very fast variations, due to environmental factors. Therefore, their availability is not guaranteed. Consequently, it is opportune to take advantage of the intrinsic flexibility of hydropower pl...
