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.

Dual Mode MPC for a Concentrated Solar Thermal Power Plant

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...

Supervisory 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...

A New Recurrent Fuzzy Neural Network Controller Design for Speed and Exhaust Temperature of a Gas Turbine Power Plant

In this paper, a recurrent fuzzy-neural network (RFNN) controller with neural network identifier in direct control model is designed to control the speed and exhaust temperature of the gas turbine in a combined cycle power plant. Since the turbine operation in combined cycle unit is considered, speed and exhaust temperature of the gas turbine should be simultaneously controlled by fuel command ...
