Abstract
This paper presents the design and evaluation of a dynamic simulator for an ISCC (integrated solar combined cycle) plant. The design of the simulator is based on the phenomenological equations for both a combined cycle plant and a solar plant. The simulator incorporates a regulatory control strategy based on PI (proportional-integral) controllers and was developed in the MATLAB/Simulink® environment. A MPC (model predictive control) strategy established at a supervisory level is presented. The intent of the strategy is to regulate the steam pressure of the superheater of the ISCC plant. The combined use of the simulator and the supervisory control strategy allows for the quantification of the reduction in fuel consumption that can be achieved when integrated solar collectors are used in a combined cycle plant. The ISCC plant simulator is suitable for designing, evaluating and testing control strategies and for planning the integration of solar and combined cycle plants.
Highlights
The construction of integrated solar combined cycle (ISCC) power plants has provided a remarkable technological contribution toward sustainable power generation [7]
This paper presents a new 128 and, to the best of our knowledge, unique contribution to ISCC plant design because no other dynamic simulator of this type has yet been reported in the literature. 130
The overshoot is lower with the supervisory controller compared with the PI 438 control strategy
Summary
The construction of integrated solar combined cycle (ISCC) power plants has provided a remarkable technological contribution toward sustainable power generation [7]. An ISCC power plant features three main components: a CC thermal power plant, a distributed collector field and a solar steam generator. The solar steam generator is the component that connects the solar collector plant to the combined cycle plant and allows for the transfer of energy between them. Preheated feed water is extracted from the high-pressure preheater, evaporated and slightly superheated in the solar steam generator. It goes to the boiler, and together with the steam from the conventional evaporator, it is superheated to reach the steam temperature. It goes to the boiler, and together with the steam from the conventional evaporator, it is superheated to reach the steam temperature. 48
