Supervisory Fuzzy Predictive Control for a Concentrated Solar Power Plant
نویسندگان
چکیده
This paper deals with the design and evaluation of the performance of fuzzy predictive controller in supervisory mode for a solar-concentration-based power plant, with cylindrical-parabolic solar collectors. For the design of the controller, the inner control loops present in this solar platform are included in the model of the plant. That is, a control loop consisting of a PI plus a feed-forward controller is considered for modeling the closed-loop behavior of the plant. With this purpose, an ARIX and a Takagi-Sugeno model are compared. As expected, the Takagi-Sugeno model performs better than the ARIX model. Therefore, Takagi-Sugeno model is used for designing the supervisory control strategy. The proposed control scheme is tested in the ACUREX simulator (the simulator of the Almeria Solar Platform). The tests included in this paper are: set-point changes, variations in the solar radiation, and modifications in the parameters of the inner control loop.

A model predictive control strategy for a concentrated solar thermal power plant is proposed. Design of the proposed controller is based on an estimated linear time-invariant state space model around a nominal operating point. The model is estimated directly from inputoutput data using the subspace identification method and taking into account the frequency response of the plant. Input-output d...
متن کاملSupervisory Control of a Hybrid AC/DC Micro-Grid with Load Shedding Based on the Bankruptcy Problem
In this paper, a supervisory controller is proposed to manage the power flow in a hybrid AC/DC micro-grid for both grid-connected and disconnected modes. When the hybrid AC/DC micro-grid is connected to the utility grid, power surplus or shortage leads to power trade between the micro-grid and the utility grid. In the grid-disconnected mode, the renewable power sources (wind and solar generatio...
