Abstract

The invention provides a wind - hydrogen coupling power generation system optimization method and device thereof. The method comprises the following steps: establishing an optimization model of a wind-hydrogen coupling power generation system based on the energy conversion of the wind-hydrogen coupling power generation system and a time recursive constraint of a hydrogen storage system; determining a daily operating profit model of the hydro-hydrogen coupling power generation system according to the established optimization model; optimizing a conversion of electric energy and hydrogen energy of power grid and hydrogen production system in wind-hydrogen coupling power generation system based on a run-day revenue model of wind-hydrogen coupling generation system; adjusting the wind - power output in the run-day revenue model of the wind - hydrogen coupling power generation system, analyzing a new energy consumption of the grid after the introduction of hydrogen production system, and an economic index of the wind-hydrogen coupling power generation system; optimizing system parameters according to the analysis of the new energy consumption of the grid after the introduction of hydrogen production system, and the economic index of the wind-hydrogen coupling power generation system; using hydrogen as a buffer hydrogen to be a by-product, balancing new energy output of each period, increasing system revenue, and improving the level of consumption.

Description

technical field [0001] The invention relates to electric power technology, in particular to an optimization method and device for a wind-hydrogen coupled power generation system. Background technique [0002] Wind power, as a clean and renewable energy that can be used in a large-scale centralized and decentralized manner, plays an important role in the national economy and energy supply. As of 2015, the total installed capacity of new energy grid-connected across the country reached 169.88 million kilowatts, of which the cumulative installed capacity of wind power reached 128.3 million kilowatts, accounting for 8.5% of the total installed capacity. %. [0003] During the rapid development of wind power, wind power accommodation faces many challenges. The characteristics of wind power, the geographical distribution of wind farms, and the transmission capacity of the power grid have intensified the problem of wind power accommodation to varying degrees. First, wind power o...
