Embodiment Construction

[0073] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0074] Please refer to figure 1 , the present invention provides a wind-hydrogen system joint optimization modeling method based on chance constrained programming, characterized in that it includes the following steps:

[0075] Step S1: Obtain the time series wind resource status of the wind farm, fit the time series of wind farm output, hydrogen system cost parameters, power transmission project parameters, and wind power feed-in price parameters to provide data support for modeling optimization;

[0076] Step S2: According to the obtained wind farm output time series, with the goal of maximizing the profit rate of capital, and satisfying the preset constraints, construct a chance-constrained programming model of the wind farm, and configure the output capacity of the wind farm and the capacity of each unit of the hydrogen system;

[0077] Step S3: Ac...

Abstract

The invention relates to a wind-hydrogen system joint optimization modeling method based on opportunity constraint planning, and the method comprises the steps: starting from the perspective of benefits of wind-hydrogen system investors, applying equal electric quantity-equal electric quantity; according to the method, the wind power fluctuation cost before and after optimization is calculated, the investment project capital profit margin (ROE) maximization is taken as the target, the uncertainty of wind power is considered, and an opportunity constraint planning model of wind power plant power transmission project and hydrogen system configuration joint optimization is constructed.

Description

technical field [0001] The invention relates to the technical field of electric power system, in particular to a joint optimization modeling method of wind-hydrogen system based on chance constraint programming. Background technique [0002] As the focus of energy development in countries around the world shifts to clean energy, renewable energy is developing rapidly. Wind power is the main utilization method of renewable energy. Its rapid and large-scale development and the randomness and intermittency of wind power make it difficult for the grid to absorb wind power, resulting in the decline of power quality, the reduction of wind power utilization rate, and the high wind abandonment rate. And then affect the economic efficiency of the whole industry. The combination of wind power and hydrogen energy storage can effectively solve the problems encountered by current wind power. On the one hand, it can solve the problem of wind power consumption by absorbing excess wind pow...
