Capacity matching optimization method of wind power generation and photothermal power generation system

Abstract

The invention discloses a capacity matching optimization method of a wind power generation and photothermal power generation system. By the capacity matching optimization method, the problem of capacity optimization and configuration of the wind power generation and photothermal power generation system is solved, and the capacity matching optimization method is used for mathematical modeling and optimization target and rule setting by a unified power generation system and is an optimization and configuration calculation method developed on the basis of an Matlab platform. The capacity matchingoptimization method comprises the steps of (a), acquiring all-year wind speed data, system power generation target data and system constraint condition data; (b), calculating wind power generation power and photothermal power generation data of an initial power generation system per hour according to a unified power generation system mathematical model; (c), calculating a fluctuation rate according to the constraint condition, a target value and the optimization rule; (d) changing capacity of a wind power generation system and a photothermal power generation system according to the set step length, repeating the steps (b) and (c), stopping calculation until minimum fluctuation ratio is solved, and outputting the capacity of the wind power system, the capacity of the photothermal power generation system and a ratio value between the capacities. By the capacity matching optimization method, the capacity optimization and configuration under minimum unified output fluctuation of the windpower generation and photothermal power generation system can be achieved.

Description

technical field [0001] The invention relates to a method for optimizing the capacity ratio of wind power generation and photothermal power generation systems, which belongs to the field of mixed utilization of different renewable energy sources. Background technique [0002] As two forms of renewable energy utilization, wind power and solar thermal power can provide people with clean and pollution-free green electricity. [0003] At present, wind power has become a renewable energy with a large development scale, and its output fluctuates greatly, and is random and intermittent; while solar thermal power has become a very potential form of utilization due to its stable and adjustable advantages, and has become Good option for hybrid development with other renewable energy technologies. For wind power practitioners, the awareness of molten salt heat storage technology in the wind power field is not high. At present, wind power storage often considers battery technology, and ...
