It is located 650m above sea level along the boundary between the North Caribbean and Pacific slopes, near the Southern end of the volcanic Guanacaste mountain range. In the early 1980s the lake's main outlet was dammed and the outflow was diverted into Arenal Reservoir. Lake Cote was first studied in 1990-1991, and later in 2001, before it was again modified by raising its dam by one meter to ...

Water is scarce resource with uncertain availability. Hence finding an optimal production schedule for hydro producer is usually a complex task and it is necessary to carefully balance the timing of water use. This paper addresses the selfscheduling problem for a price-taker hydro producer. The goal is maximizing the profit of a hydro producer through participating in the day-ahead energy and a...

In this paper, a method for long-term optimal operation of hydropower station is proposed to control the frequency reservoir level fluctuation. We introduce integer variable which describes rise and fall level, number changes, state transition equation change fluctuation into dynamic programming method. This can obtain global solution under different numbers fall, thus improving controllability...

We present an \asset/liability" model for a hydropower producer operating in a deregulated electricity market. The focus in this modeling eeort is on the coordination of physical generation resources in the form of multiple hydropower reservoirs, with \paper" resources in the form of nancial instruments on electricity. These portfolio management instruments are available in functioning forward ...

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...

Inflow data plays an important role in water and energy resources planning and management. In general, due to the limited availability of historical inflow data, synthetic streamflow time series have been widely used for several applications such as midand long-term hydropower scheduling and the identification of hydrological processes. This paper explores the use of fuzzy inference systems for...

This paper presents part of the work carried out within the framework of a research project entitled Application of variable speed and intelligent control technologies to hydropower generation. Specifically, it is focused on the activities performed in order to achieve one of the main objectives of the project: the design of a water level control system for a low-head run-of-river variable spee...

Information is provided about the approach and experience in flood management in the Damodar river basin of India. This is achieved through a scheme for the integrated operation of a number of reservoirs on that river and on its tributaries for the purpose of irrigation, hydropower generation and flood protection. Of particular interest is the recent change in policy towards a multi-disciplinar...
