Embodiment Construction

[0032] Such as figure 1 As shown, the photothermal photovoltaic bundling power generation system of the present invention is composed of a photothermal photovoltaic sub-system 1 and a photovoltaic sub-system 2 . The photothermal power generation sub-system 1 is composed of three parts: a heat absorption tower 3 , a heat storage device 4 and a power generation device 5 . Photovoltaic power generation subsystem 2 is composed of photovoltaic array and inverter. The characteristic of this system is that due to the existence of the heat storage device in the energy exchange subsystem, the photothermal power generation sub-system has the characteristics of energy time shift, which can effectively reduce the output fluctuation of photovoltaic power generation, improve the power quality of the system, and ensure the stable supply of power.

[0033] Such as figure 2 As shown, the present invention is a method for configuring the capacity of a photothermal photovoltaic bundling power...

Abstract

Based on the capacity allocation method of the solar-thermal photovoltaic bundled power generation system based on the cuckoo search, aiming at the output fluctuation problem of the photovoltaic power station, a matching solar-thermal power station is established to form a solar-thermal photovoltaic bundled power generation system. Based on the historical data of solar radiation intensity, a method of improving system capacity allocation through cuckoo search is proposed on the basis of fully consuming photovoltaic power generation, with the goal of minimizing the output standard deviation of the solar-thermal photovoltaic bundled power generation system.

Description

technical field [0001] The invention relates to a capacity configuration method of a photothermal photovoltaic bundling power generation system based on cuckoo search. Background technique [0002] Due to the year-by-year reduction of fossil energy and the increasing environmental pollution, it is extremely urgent to develop new power generation technologies. Photothermal power generation has attracted widespread attention due to its superior power generation characteristics, and is about to usher in a period of rapid development. Compared with other new energy power generation technologies, the adjustment ability of solar thermal power generation can be compared with that of thermal power units, and it can realize "consuming renewable energy with renewable energy". Key technical means. [0003] The output of photovoltaic power generation is easily affected by weather conditions and is random and volatile. Photothermal power generation is equipped with a corresponding hea...
