The Azad pumped storage power plant including the pumping and transformer cavern and surge tanks has been located in the Sanandaj-Sirjan formation with the alternation of slate and phyllite and meta sandstone.Due to the sensitivity and special use of these spaces, stability analysis and ensuring the safety of carven is very important.Nowadays, using the surface storage tanks is very costly; The...
It is very important, to optimize of clean electrical energy by employing of variable Speed pumped storage power plant (VSPSP). Variable speed machines are used extensively in wind power plants and pumped storage power plants. Therefore, the advantages of this technology are including: stability, reliability, fast dynamic responses, frequency control and high efficiency of power system. By usin...
The integration of renewable wind and pumped storage with thermal power generation allows for dispatch of wind energy by generation companies (GENCOs) interested in participation in energy and ancillary services markets. However, to realize the maximum economic profit, optimal coordination and accounting for reduction in cost for environmental emission is necessary. The goal of this study is to...
This work analyses the configuration and operation principles of hybrid wind-hydro power plants with pumped storage integrated into autonomous electric grid systems, in order to support high wind energy penetration. The plant consists of wind generation units, combined with a pumped-hydro storage system. It operates on a daily basis, storing the surplus wind production by pumping water in an el...
In a molten-salt solar power tower, liquid salt at 290oC (554oF) is pumped from a ‘cold’ storage tank through the receiver where it is heated to 565oC (1,049oF) and then on to a ‘hot’ tank for storage. When power is needed from the plant, hot salt is pumped to a steam generating system that produces superheated steam for a conventional Rankinecycle turbine/generator system. From the steam gener...
In this paper, a neural Pseudoderivative control (PDF) is applied to a nonlinear mathematical model of the Dinorwig pumped storage hydroelectric power station. The response of the system with this auto-tuning controller is compared with that of a classic controller, currently implemented on the system. The results show how the application of PDF control to a hydroelectric pumped-storage station...
The article presents simulation results of a developed model PSP Solina. was designed and executed in the Matlab – Simulink interface. A modular approach used to clearly distinguish characteristic elements model. Simulations performance were carried out for period 365 days. presented graphically. To simplify, form criteria defining on/off moments turbine/pump turbine operating mode adopted. All...
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...
