To enable power supply in rural areas and to exploit clean energy, fully renewable systems consisting of cascaded run-of-the-river hydropower volatile energies such as pv wind are built around the world. In islanded operation mode, primary secondary frequency control, i.e., hydro governors automatic generation control (AGC), responsible for stability. However, due limited water storage capacity...

introduction despite the abundant renewable energy sources, the iranian energy sector relies almost entirely on fossil fuel energy resources. power sector is dominant source of co2emissions and responsible for about 35% of total co2 emissions in the country. additionally, long-term electricity demand of iran is expected to grow quickly, which in turn requires extensive investment to meet the gr...

Renewable energy resources have played an important role to meet increasing energy demand in the world. Among the renewable energy resources, especially, wind energy is of interest due to some advantages, such as being clean, environmental friendly etc. However, the intermittent nature of wind creates several problems to the power system operation and new approaches based on the combined use of...

Renewable energy is a source of energy derived from natural resources such as sunlight, wind, water, tides, hot dry rocks, magma, hot water springs, fire wood, animal manure, and crop residues and waste. These renewable energy technologies are called with its source such as solar power, wind power, hydropower, geothermal and biomass. Energy resources are so important in perspective of economics...

the renewable energy sources and plug-in electric vehicles (pevs) are becoming very popular because of the combination of high fuel costs and concerns about emission issues. this paper presents modelling and control of a building integrated fuel cell and plug-in electric vehicles (bifc-pev) in smart distribution systems. in bifc-pev system, conventional building elements could be replaced by sp...

The benefits of potential electric power transfers between the Pacific Northwest (PNW) and California (CA) are evaluated using a linked set of hydrologic, reservoir, and power demand simulation models for the Columbia River and the Sacramento–San Joaquin reservoir systems. The models provide a framework for evaluating climate-related variations and long-range predictability of regional electric...

River tributaries have a key role in the biophysical functioning of the Mekong Basin. Of particular interest are the Sesan, Srepok, and Sekong (3S) rivers, which contribute nearly a quarter of the total Mekong discharge. Forty two dams are proposed in the 3S, and once completed they will exceed the active storage of China’s large dam cascade in the Upper Mekong. Given their proximity to the Low...

The Mekong River in Southeast Asia stands at the crossroads. As discussed in Ambio Special Issue (Kummu et al. 2008), the crossroads is ultimately about the way the river and its abundant resources should be used, with the most heated debate evolving around the issue of large hydropower dams. A relatively pristine river with an estimated hydropower potential of 53000MW in the basin, the Mekong ...

In this paper we discuss how three different public policy measures affect water storage controlled by hydropower producing firms. In particular we discuss measures to promote competition, increase transmission capacity and rationing. The analysis is conducted within the framework of an oligopoly model where 2 hydro producing firms engage in dynamic Bertrand competition. We extend this model to...
