Abstract The presence of mineral sediments in water led to significant erosion damage a power plant the Chilean Andes. is operated by Enel and equipped with three vertical Francis units, approximately 25 MW each operating under net head around 120 m. overall machine condition reported on turbine caused modernization project runner replacement output efficiency increase. In order ensure proper s...

In this paper we analyze whether real-time compensation of wind power plant deviation penalties is profitable by means of the coordinated optimization of the wind power plant with a pumped-storage hydro-plant. We shall make use of optimal control techniques to carry out the optimization. We shall also analyze another possible solution based on compensation carried out a posteriori, instead of i...

This study addresses a stochastic structure for generation companies (GenCoʼs) that participate in hydro-thermal self-scheduling with a wind power plant on short-term scheduling for simultaneous reserve energy and energy market. In stochastic scheduling of HTSS with a wind power plant, in addition to various types of uncertainties such as energy price, spinning /non-spinning reserve prices, unc...

The excitation system of the hydro unit is a static self-excitation that uses thyristor rectifiers in three-phase fully controllable bridge connection with digital two-channel regulation characterized by very fast response (eng. high initial ratio). powered an transformer connected to busbars aggregate transmission ratio 14.4/0.42 kV. aim this project show characteristics old ABB UNITROL 5000 a...

The three renewable energy technologies discussed in this paper are based on water, but differ markedly in terms of the size of the available potential resource, the maturity of the associated conversion technologies, the extent to which they have been exploited to date, and the current research effort being devoted to their future development. Hydro-electricity and tidal power are both very ma...

The human demand for electricity and fresh water is ever increasing. Due to the nature of hydropower and its economic, social, and environmental benefits, hydropower will be an important contributor to the energy mix of the future. Isolated areas, severely underdeveloped regions, disaster-stricken zones, and remote military outposts have one common need: readily available and efficient means of...
