Embodiment Construction

[0057] The present invention will be further described below in conjunction with the accompanying drawings and examples.

[0058] like figure 1 A new energy consumption restriction evaluation method based on combination weighting-gray correlation is shown, which specifically includes the following steps:

[0059] Step 1: Establish a comprehensive evaluation index system for new energy consumption constraints, which includes 4 types of first-level indicators and 8 second-level indicators. Step 1 is now further explained:

[0060] According to the actual experience of power grid operation and related theoretical research results, the main factors restricting the capacity of new energy consumption are grid transmission capacity, new energy penetration rate, power grid regulation capacity and load characteristics. Apply the idea of ​​hierarchical classification to establish an index system, and build a comprehensive evaluation index system for new energy consumption constraints ...

Abstract

The invention discloses a new energy consumption restriction factor evaluation method and system based on combination empowerment grey correlation. The method comprises the steps of establishing a newenergy consumption restriction factor comprehensive evaluation index system in a layered manner; performing quantitative evaluation on the secondary indexes by adopting a combined weighting method toobtain a combined weight; evaluating the index system by adopting a gray correlation method, and obtaining the influence degree of the first-level indexes. According to the combined weighting methodadopted by the invention, subjective and objective weights can be fully combined, the internal relation between index data is analyzed while expert knowledge and experience are used for reference, andthe new energy consumption evaluation index weight selection is more scientific and accurate.

Description

technical field [0001] The invention belongs to the technical field of electric power system evaluation, and in particular relates to an evaluation method and system for new energy consumption restriction factors based on combination weighting-gray correlation. Background technique [0002] Affected by unstable natural conditions such as wind speed and light intensity, both wind power and photovoltaic power generation have obvious uncertainties, difficult controllability, and temporal and spatial distribution characteristics, and their large-scale connection also brings a series of urgent problems to the power system. question. New energy consumption is a systematic project, which is closely related to various factors such as electricity demand, grid structure, peak-shaving capability, and system stability. [0003] After large-scale new energy is connected to the grid, the fundamental reason restricting its consumption capacity is insufficient system regulation capacity. T...
