Benchmarking photovoltaic plant based evaluation method for light and power abandonment amount of large photovoltaic power generation cluster

Abstract

The invention discloses a benchmarking photovoltaic plant based evaluation method for a light and power abandonment amount of a large photovoltaic power generation cluster. The method comprises: setting a statistic time period, a collection time interval and a statistic range of a photovoltaic cluster, wherein the statistic time is longer than the collection time interval; at the beginning of the statistic time, obtaining an average force-voltage factor of all benchmarking photovoltaic plants within the collection time interval; within the statistic time period, according to the obtained average force-voltage factor and by taking the collection time interval as a statistic unit, making statistics on the light and power abandonment amount of the photovoltaic cluster based on each benchmarking photovoltaic plant; and at the end of the statistic time period, obtaining the light and power abandonment amount of the photovoltaic cluster based on all benchmarking photovoltaic plants within the statistic time period. According to the scheme, the shortcomings in the prior art of complicated processing process, small applicable range, difficulty in obtaining calculation data, low calculation accuracy and the like can be overcome, so that the advantages of simple processing process, wide applicable range, rapidness for calculation and high calculation accuracy can be realized.

Description

technical field [0001] The present invention relates to the technical field of photovoltaic power generation abandoned light quantity evaluation technology, in particular, relates to a large-scale photovoltaic power generation cluster waste light quantity assessment method based on a benchmark photovoltaic power station. Background technique [0002] Photovoltaic power station abandoned photovoltaic power refers to the power that can be generated by photovoltaic power stations but cannot be generated due to factors such as grid transmission channel restrictions, grid peak regulation needs, grid safety and stability operation needs, and grid equipment maintenance and failures. [0003] Light abandonment is a common phenomenon in the process of large-scale development of photovoltaic power generation, similar to water abandonment in the process of hydropower generation. Large-scale photovoltaic power generation bases cover a wide area and generally include multiple photovoltai...
