This paper deals with a model that comprises the pumped-storage hydro power plants in system reliability and availability calculations, as well of impact inflow deficiency water storage risks on operational planning such within framework systems for periods up to one year. The uncertainties is related characteristics watercourses where reservoirs are built, but also operation cycles possible mo...

In hierarchical distributed control systems for hydro power groups located over a large area, there are requirements for independent (autonomous) operation of control systems for each power group (or parts of the group), to solve local problems or in case of real-time faults over communication paths with upper levels. In this case, the control equipment for power groups may be defined as holons...

Micro-hydro-electric power is both an efficient and reliable formof clean source of renewable energy. It can be an excellent method of harnessing renewable energy from small rivers and streams. The micro-hydro project designed to be a run -of-river type, because it requires very little or no reservoir in order to power the turbine. The water will run straight through the turbine and back into t...

Mathematical models for the electricity portfolio management of a utility that owns a hydro-thermal generation system and trades on the power market often lead to complex stochastic optimization problems. We present a new approach to solving stochastic hydro-storage subproblems that occur when stochastic Lagrangian relaxation is applied to solving such models. The special structure of such hydr...

ABSRACT Sliding mode control has received much attention due to its major advantages such as guaranteed stability, robustness against parameter variations, fast dynamic response and simplicity in the implementation and therefore has been widely applied to control nonlinear systems. This paper discus the sliding mode control technic for controlling hydropower system and generalized a model which...

Objective: Rosa damascena mill L. (R. damascena) is a well-known plant with fragrant effects. Several therapeutic effects of this plant on respiratory, gastrointestinal and nervous systems have been reported. It is also suggested to have beneficial effect on cardiovascular system especially blood pressure regulation. The present study was carried out to evaluate acute cardiovascular effect of h...
