In this paper aspects related to handling of intraday imbalances for hydro and wind power are addressed. The definition imbalance cost is established used describe the potential benefits shifting from plant-specific schedules a common load requirement hydropower units in same price area. Nordpool pay-as-bid market has been basis evaluation imbalances, some main characteristics described. We con...

The development of fluorescent probes for superoxide and the hydroxyl radical is a central problem in the field of chemical biology. Superoxide and the hydroxyl radical play a significant role in a variety of inflammatory diseases, and probes that can detect these reactive oxygen species (ROS) have tremendous potential as medical diagnostics and research tools. Fluorescent sensors for superoxid...

This paper proposes a robust optimization model for optimal self scheduling of a hydro-thermal generating company. The proposed model is suitable for price taker Gencos which seeks the optimal schedule of its thermal and hydro generating units for a given operating horizon. The uncertainties of electricity prices are modeled using robust optimization approach to make it more practical. It consi...

This paper considers a condition-based maintenance (i.e. CBM) model for the hydro generating unit in the deregulated power system. As the downtime cost of the generating unit varies according to the time-varying electricity price, the economic dependence among the critical component of the generating unit is dynamic. In this paper, the proposed DynamicEconomic-Dependence and proportional hazard...

This article presents a distributed real-time control system for the southern grid of the Cameroon power system. The southern grid, which supplies over 90 % of the power output in Cameroon, incorporates two remotely located hydro-electric generating stations, a power distribution center, several thermal plants and hundreds of kilometers of transmission lines. The proposed distributed control sy...

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...

We investigate the surface gravity and hydro-acoustic wave fields, generated by the 2011 Tohoku-Oki tsunamigenic event using a numerical model based on a computationally efficient depth-integrated equations for a compressible water column coupled to a dissipative sedimentary layers. Spectral analysis of bottom pressure time series obtained in deep water revealed the role of underlying layer on ...

nowadays,it is important to consider environmental issues,as ecological problems and their severe effect intensify in iran,particularly in khuzestan province.the environmental effects of hydroelectric plants are highly regarded due to their significant impact on an extensive area.the lack of safe path for fish passing through the turbines is one of these damages. in order to deal with these cha...

The HYDRO mini-application has been successfully used as a research vehicle in previous PRACE projects [6]. In this paper, we evaluate the benefits of the tasking model introduced in recent OpenMP standards [9]. We have developed a new version of HYDRO using the concept of OpenMP tasks and this implementation is compared to already existing and optimized OpenMP versions of HYDRO.
