Many renewable energy sources are not able to provide the demanded electrical energy during the day. This problem is getting more important with the increase of power plants which are based on renewable energy. The proposed method for overcoming the aforementioned problem is the building of hybrid power plants with two or three different energy sources. The most common hybrid power plants are solar-wind...
Renewable energy sources in addition to all the advantages over the non-renewable energy sources have a lot of limitations, where the biggest of them are the price and the inability of constant electricity generation. One way of overcoming the problem of inability of constant electricity generation is to build hybrid power plants with renewable energy sources. This primarily highlights hybrid solar...
This paper proposes a new closed-loop frequency based method for parametric identification of Hammerstein type plants with a transport delay. The method is a generalization of Ziegler Nichols' (ZN) experiment, with relay added in the control loop. It provides a simultaneous estimation of the parametric model of the plant dynamic, value of the time delay and a point by point relationship between input...
This paper proposes a new closed loop frequency based method for a parametric identification of some types of Wiener-type nonlinear plants. It provides a parametric model of the linear part of the plant, and a point by point relationship between input and output of the nonlinear part of the plant. Two approaches are proposed for the identification of the nonlinear part. The first approach is slower,...
This paper proposes a closed-loop frequency-based method for parametric identification of Wiener type plants with a transport delay in the linear part using a relay feedback. The method is a generalization of Ziegler Nichols' (ZN) experiment, with relay added in the control loop. It provides a simultaneous estimation of the linear plant dynamic, value of the time delay and approximate model of the...
