Embodiment Construction

[0016] The invention is a method for maximizing power generation optimization based on a static model of a CSP power station. Such as figure 1 As shown, the TSS charging and discharging control strategy inside the CSP power station can be optimized to achieve the purpose of improving the CSP power generation and overall operating efficiency. Aiming at the large lag link in the control process, the Smith predictor compensator is used to compensate, and the specific invention steps are as follows:

[0017] Step 1: Comprehensively analyze the typical static model and operation mode of the CSP power station, and obtain that the charging power P of the thermal storage subsystem (Thermal Storage Subsystem, TSS) can be optimized t S-T and heat release power P t T-P method to achieve the goal of optimizing the power generation of CSP power plants. After introducing the charging power coefficient α∈[0,1] and the discharging power coefficient β∈[0,1], the charging and discharging e...

Abstract

The invention discloses a static model-based photo-thermal power station generating capacity optimization method. The method comprises the steps of firstly analyzing a controllable part influencing the power station generating capacity in a static model; secondly, establishing an optimization mathematical model by taking the maximum generating capacity as a target function and the constraint condition of the static model, and proposing an optimization method; and finally, introducing a Smith pre-estimation compensation mechanism to reduce the influence of a large lag link appearing in the control system on the stability and accuracy of the system. The optimization method can effectively improve the generating capacity and the operation efficiency of the photo-thermal energy storage power station.

Description

technical field [0001] The invention relates to a power generation optimization method based on a static model of a photothermal energy storage power station. Background technique [0002] In recent years, the Concentrating Solar Power (CSP) method has become an important power generation method to solve new energy generation and power grid volatility and randomness by virtue of its advantages of rapid output adjustment. The existing ways to increase the power generation of solar thermal energy storage power plants mainly include improving heat storage media, optimizing heat storage methods, and control methods based on thermodynamic dynamic models, but none of the above methods are suitable for long-term scale of solar thermal energy storage power plants. optimization. Among them, the control method based on the thermodynamic dynamic model needs to detect too much, and the working environment of the detection element is relatively harsh, so it is not suitable for long-term...
