Today, the widespread use of fossil fuels is caused many problems in the world, which include: Ozone depletion, the increase carbon dioxide in the atmosphere, growing recognition of climate change impacts and decreasing fossil fuel resources. These issues have led to an increased interest in the mass generation of electricity from renewable sources such tidal energy. The Khowr-e Musa Estuary, l...

The growth of population, rising fossil fuel prices (limited and decreasing day by day), pollution problem due to use of fossil fuels and increasing electrical demand are important factors that encourage the use of green and renewable energy technologies. Among the different renewable energy technologies, hydro power generation (large and small scale) is the prime choice in terms of contributio...

This letter introduces a method to manage energy storage in electricity grids. Starting from the stochastic characterization of electricity generation and demand, we propose an equation that relates the storage level for every time-step as a function of its previous state and the realized surplus/deficit of electricity. Therefrom, we can obtain the probability that, in the next time-step: (i) t...

In recent years, energy predicament and environmental problems in the world caused by fossil fuels combustion make us to pay serious attention to optimizing energy consumption and using renewable energies. One of the potential renewable energies which can be helpful in electricity generation is harness wind and water energy or using these two kinds of energy simultaneously. In this study, to pr...

This paper investigates three models to implement Tradable Green Certificates (TGC) system with aid of game theory approach. In particular, the competition between thermal and renewable power plants is formulated in three models: namely cooperative, Nash and Stackelberg game models. The price of TGC is assumed to be determined by the legislative body (government) which is fixed. Numerical examp...

Hydro-electric power utilities convert the potential energy of water to electricity through the operation of generation turbines. Each turbine unit has an operating range and incurs a fixed start-up cost. The problem of determining which turbines should be operating at any point during the day whilst ensuring that the demand for electricity is satisfied is known as the unit commitment problem. ...

This paper examines the effect of subsidized entry of electricity generation capacity on the outcome of centralized capacity auctions. Subsidized entry suppresses capacity prices and induces an inefficient allocation of capacity. Subsidized entry also alters the generation portfolio determined by the capacity auction, leading to lower expected electricity prices in subsequent market interaction...

In this paper, we analyze the potential for solar photovoltaics (PV) to be deployed on a very large scale and provide a large fraction of a system’s electricity. We explicitly examine how the hourly availability of PV interacts with the limited flexibility of traditional electricity generation plants. We find that under high penetration levels and existing grid-operation procedures and rules, t...

The 2003 Indian Electricity Act incentivizes captive power production through open access in an attempt to harness all sources of generation. Yet, we observe that only some firms self-generate while others do not. In this paper we give a transaction cost explanation for such divergent behavior. Using a primary survey of 107 firms from India, we construct a distinct variable to measure the trans...

All over the world Distributed Generation is seen as a valuable help to get cleaner and more efficient electricity. Under this context distributed generators, owned by different decentralized players can provide a significant amount of the electricity generation. To get negotiation power and advantages of scale economy, these players can be aggregated giving place to a new concept: the Virtual ...
