Renewable energy subsidies in the form of feed-in tariffs implicitly give investors the possibility to shut down their renewable power plants temporarily or permanently. This real option is especially valuable for electricity from biomass, an important pillar of European renewable energy goals. The shut-down option is similar to a put on agricultural commodity prices, while the costs and benefi...

Improving the efficiency and flexibility of fossil-fired power plants remains a current challenging issue. In that regard, supercritical CO2 Brayton cycles offer promising potential. This paper aims to apply process synthesis approach design closed cycle using as working fluid with coal furnace heat source. The general methodology presented here for designing includes construction superstructur...

Energy generated by the force of water in hydropower can provide a more sustainable, non-polluting alternative to fossil fuels, along with other renewable sources of energy, such as wind, solar and tidal power, bio energy and geothermal energy. Small scale hydroelectricity in Iran is well suited for “off-grid” rural electricity applications, while other renewable energy sources, such as wind, s...

Dynamic simulation models using powerful personal digital computers are a very cost effective tool for studying the operating characteristics of power plants to improve the design and control strategy to meet stringent operational requirements. The required operating modes of large fossil fuelled generating plants call for continued operation after load rejection, and rapid, frequent and reliab...

The use of renewable energies, especially in metropolises has led to a reduction in environmental pollution and greater access to clean, renewable and sustainable energy. This paper evaluates the effectiveness of a national plan adopted by the Tehran city council for reducing air pollutions. This plan is designed to increase the share of renewable energies in residential buildings. This study a...

In many European countries, natural gas-fired power plants are considered a possibility to quickly compensate the expected shortfall in electric energy supply. Increasing gasfired generation capacity would also increase the couplings and interactions between gas and electricity systems. So far, gas power plants participate in two different markets gas and electricity. Coupling these markets by ...

Intensified industrialization in developing countries has recently resulted in huge electric power demand growth; however, electricity generation in these countries is still heavily reliant on inefficient and traditional non-renewable technologies. In this paper, we develop an integrated game-theoretic model for effective power systems planning thorough balancing between supply and demand for e...
